1CONFIGURATION FILE 2------------------ 3 4The git configuration file contains a number of variables that affect 5the git command's behavior. `.git/config` file for each repository 6is used to store the information for that repository, and 7`$HOME/.gitconfig` is used to store per user information to give 8fallback values for `.git/config` file. The file `/etc/gitconfig` 9can be used to store system-wide defaults. 10 11They can be used by both the git plumbing 12and the porcelains. The variables are divided into sections, where 13in the fully qualified variable name the variable itself is the last 14dot-separated segment and the section name is everything before the last 15dot. The variable names are case-insensitive and only alphanumeric 16characters are allowed. Some variables may appear multiple times. 17 18Syntax 19~~~~~~ 20 21The syntax is fairly flexible and permissive; whitespaces are mostly 22ignored. The '#' and ';' characters begin comments to the end of line, 23blank lines are ignored. 24 25The file consists of sections and variables. A section begins with 26the name of the section in square brackets and continues until the next 27section begins. Section names are not case sensitive. Only alphanumeric 28characters, '`-`' and '`.`' are allowed in section names. Each variable 29must belong to some section, which means that there must be section 30header before first setting of a variable. 31 32Sections can be further divided into subsections. To begin a subsection 33put its name in double quotes, separated by space from the section name, 34in the section header, like in example below: 35 36-------- 37 [section "subsection"] 38 39-------- 40 41Subsection names can contain any characters except newline (doublequote 42'`"`' and backslash have to be escaped as '`\"`' and '`\\`', 43respectively) and are case sensitive. Section header cannot span multiple 44lines. Variables may belong directly to a section or to a given subsection. 45You can have `[section]` if you have `[section "subsection"]`, but you 46don't need to. 47 48There is also (case insensitive) alternative `[section.subsection]` syntax. 49In this syntax subsection names follow the same restrictions as for section 50name. 51 52All the other lines are recognized as setting variables, in the form 53'name = value'. If there is no equal sign on the line, the entire line 54is taken as 'name' and the variable is recognized as boolean "true". 55The variable names are case-insensitive and only alphanumeric 56characters and '`-`' are allowed. There can be more than one value 57for a given variable; we say then that variable is multivalued. 58 59Leading and trailing whitespace in a variable value is discarded. 60Internal whitespace within a variable value is retained verbatim. 61 62The values following the equals sign in variable assign are all either 63a string, an integer, or a boolean. Boolean values may be given as yes/no, 640/1 or true/false. Case is not significant in boolean values, when 65converting value to the canonical form using '--bool' type specifier; 66'git-config' will ensure that the output is "true" or "false". 67 68String values may be entirely or partially enclosed in double quotes. 69You need to enclose variable value in double quotes if you want to 70preserve leading or trailing whitespace, or if variable value contains 71beginning of comment characters (if it contains '#' or ';'). 72Double quote '`"`' and backslash '`\`' characters in variable value must 73be escaped: use '`\"`' for '`"`' and '`\\`' for '`\`'. 74 75The following escape sequences (beside '`\"`' and '`\\`') are recognized: 76'`\n`' for newline character (NL), '`\t`' for horizontal tabulation (HT, TAB) 77and '`\b`' for backspace (BS). No other char escape sequence, nor octal 78char sequences are valid. 79 80Variable value ending in a '`\`' is continued on the next line in the 81customary UNIX fashion. 82 83Some variables may require special value format. 84 85Example 86~~~~~~~ 87 88 # Core variables 89 [core] 90 ; Don't trust file modes 91 filemode = false 92 93 # Our diff algorithm 94 [diff] 95 external = /usr/local/bin/diff-wrapper 96 renames = true 97 98 [branch "devel"] 99 remote = origin 100 merge = refs/heads/devel 101 102 # Proxy settings 103 [core] 104 gitProxy="ssh" for "kernel.org" 105 gitProxy=default-proxy ; for the rest 106 107Variables 108~~~~~~~~~ 109 110Note that this list is non-comprehensive and not necessarily complete. 111For command-specific variables, you will find a more detailed description 112in the appropriate manual page. You will find a description of non-core 113porcelain configuration variables in the respective porcelain documentation. 114 115core.fileMode:: 116 If false, the executable bit differences between the index and 117 the working copy are ignored; useful on broken filesystems like FAT. 118 See linkgit:git-update-index[1]. True by default. 119 120core.ignoreCygwinFSTricks:: 121 This option is only used by Cygwin implementation of Git. If false, 122 the Cygwin stat() and lstat() functions are used. This may be useful 123 if your repository consists of a few separate directories joined in 124 one hierarchy using Cygwin mount. If true, Git uses native Win32 API 125 whenever it is possible and falls back to Cygwin functions only to 126 handle symbol links. The native mode is more than twice faster than 127 normal Cygwin l/stat() functions. True by default, unless core.filemode 128 is true, in which case ignoreCygwinFSTricks is ignored as Cygwin's 129 POSIX emulation is required to support core.filemode. 130 131core.trustctime:: 132 If false, the ctime differences between the index and the 133 working copy are ignored; useful when the inode change time 134 is regularly modified by something outside Git (file system 135 crawlers and some backup systems). 136 See linkgit:git-update-index[1]. True by default. 137 138core.quotepath:: 139 The commands that output paths (e.g. 'ls-files', 140 'diff'), when not given the `-z` option, will quote 141 "unusual" characters in the pathname by enclosing the 142 pathname in a double-quote pair and with backslashes the 143 same way strings in C source code are quoted. If this 144 variable is set to false, the bytes higher than 0x80 are 145 not quoted but output as verbatim. Note that double 146 quote, backslash and control characters are always 147 quoted without `-z` regardless of the setting of this 148 variable. 149 150core.autocrlf:: 151 If true, makes git convert `CRLF` at the end of lines in text files to 152 `LF` when reading from the filesystem, and convert in reverse when 153 writing to the filesystem. The variable can be set to 154 'input', in which case the conversion happens only while 155 reading from the filesystem but files are written out with 156 `LF` at the end of lines. Currently, which paths to consider 157 "text" (i.e. be subjected to the autocrlf mechanism) is 158 decided purely based on the contents. 159 160core.safecrlf:: 161 If true, makes git check if converting `CRLF` as controlled by 162 `core.autocrlf` is reversible. Git will verify if a command 163 modifies a file in the work tree either directly or indirectly. 164 For example, committing a file followed by checking out the 165 same file should yield the original file in the work tree. If 166 this is not the case for the current setting of 167 `core.autocrlf`, git will reject the file. The variable can 168 be set to "warn", in which case git will only warn about an 169 irreversible conversion but continue the operation. 170+ 171CRLF conversion bears a slight chance of corrupting data. 172autocrlf=true will convert CRLF to LF during commit and LF to 173CRLF during checkout. A file that contains a mixture of LF and 174CRLF before the commit cannot be recreated by git. For text 175files this is the right thing to do: it corrects line endings 176such that we have only LF line endings in the repository. 177But for binary files that are accidentally classified as text the 178conversion can corrupt data. 179+ 180If you recognize such corruption early you can easily fix it by 181setting the conversion type explicitly in .gitattributes. Right 182after committing you still have the original file in your work 183tree and this file is not yet corrupted. You can explicitly tell 184git that this file is binary and git will handle the file 185appropriately. 186+ 187Unfortunately, the desired effect of cleaning up text files with 188mixed line endings and the undesired effect of corrupting binary 189files cannot be distinguished. In both cases CRLFs are removed 190in an irreversible way. For text files this is the right thing 191to do because CRLFs are line endings, while for binary files 192converting CRLFs corrupts data. 193+ 194Note, this safety check does not mean that a checkout will generate a 195file identical to the original file for a different setting of 196`core.autocrlf`, but only for the current one. For example, a text 197file with `LF` would be accepted with `core.autocrlf=input` and could 198later be checked out with `core.autocrlf=true`, in which case the 199resulting file would contain `CRLF`, although the original file 200contained `LF`. However, in both work trees the line endings would be 201consistent, that is either all `LF` or all `CRLF`, but never mixed. A 202file with mixed line endings would be reported by the `core.safecrlf` 203mechanism. 204 205core.symlinks:: 206 If false, symbolic links are checked out as small plain files that 207 contain the link text. linkgit:git-update-index[1] and 208 linkgit:git-add[1] will not change the recorded type to regular 209 file. Useful on filesystems like FAT that do not support 210 symbolic links. True by default. 211 212core.gitProxy:: 213 A "proxy command" to execute (as 'command host port') instead 214 of establishing direct connection to the remote server when 215 using the git protocol for fetching. If the variable value is 216 in the "COMMAND for DOMAIN" format, the command is applied only 217 on hostnames ending with the specified domain string. This variable 218 may be set multiple times and is matched in the given order; 219 the first match wins. 220+ 221Can be overridden by the 'GIT_PROXY_COMMAND' environment variable 222(which always applies universally, without the special "for" 223handling). 224 225core.ignoreStat:: 226 If true, commands which modify both the working tree and the index 227 will mark the updated paths with the "assume unchanged" bit in the 228 index. These marked files are then assumed to stay unchanged in the 229 working copy, until you mark them otherwise manually - Git will not 230 detect the file changes by lstat() calls. This is useful on systems 231 where those are very slow, such as Microsoft Windows. 232 See linkgit:git-update-index[1]. 233 False by default. 234 235core.preferSymlinkRefs:: 236 Instead of the default "symref" format for HEAD 237 and other symbolic reference files, use symbolic links. 238 This is sometimes needed to work with old scripts that 239 expect HEAD to be a symbolic link. 240 241core.bare:: 242 If true this repository is assumed to be 'bare' and has no 243 working directory associated with it. If this is the case a 244 number of commands that require a working directory will be 245 disabled, such as linkgit:git-add[1] or linkgit:git-merge[1]. 246+ 247This setting is automatically guessed by linkgit:git-clone[1] or 248linkgit:git-init[1] when the repository was created. By default a 249repository that ends in "/.git" is assumed to be not bare (bare = 250false), while all other repositories are assumed to be bare (bare 251= true). 252 253core.worktree:: 254 Set the path to the working tree. The value will not be 255 used in combination with repositories found automatically in 256 a .git directory (i.e. $GIT_DIR is not set). 257 This can be overridden by the GIT_WORK_TREE environment 258 variable and the '--work-tree' command line option. It can be 259 a absolute path or relative path to the directory specified by 260 --git-dir or GIT_DIR. 261 Note: If --git-dir or GIT_DIR are specified but none of 262 --work-tree, GIT_WORK_TREE and core.worktree is specified, 263 the current working directory is regarded as the top directory 264 of your working tree. 265 266core.logAllRefUpdates:: 267 Enable the reflog. Updates to a ref <ref> is logged to the file 268 "$GIT_DIR/logs/<ref>", by appending the new and old 269 SHA1, the date/time and the reason of the update, but 270 only when the file exists. If this configuration 271 variable is set to true, missing "$GIT_DIR/logs/<ref>" 272 file is automatically created for branch heads. 273+ 274This information can be used to determine what commit 275was the tip of a branch "2 days ago". 276+ 277This value is true by default in a repository that has 278a working directory associated with it, and false by 279default in a bare repository. 280 281core.repositoryFormatVersion:: 282 Internal variable identifying the repository format and layout 283 version. 284 285core.sharedRepository:: 286 When 'group' (or 'true'), the repository is made shareable between 287 several users in a group (making sure all the files and objects are 288 group-writable). When 'all' (or 'world' or 'everybody'), the 289 repository will be readable by all users, additionally to being 290 group-shareable. When 'umask' (or 'false'), git will use permissions 291 reported by umask(2). When '0xxx', where '0xxx' is an octal number, 292 files in the repository will have this mode value. '0xxx' will override 293 user's umask value, and thus, users with a safe umask (0077) can use 294 this option. Examples: '0660' is equivalent to 'group'. '0640' is a 295 repository that is group-readable but not group-writable. 296 See linkgit:git-init[1]. False by default. 297 298core.warnAmbiguousRefs:: 299 If true, git will warn you if the ref name you passed it is ambiguous 300 and might match multiple refs in the .git/refs/ tree. True by default. 301 302core.compression:: 303 An integer -1..9, indicating a default compression level. 304 -1 is the zlib default. 0 means no compression, 305 and 1..9 are various speed/size tradeoffs, 9 being slowest. 306 If set, this provides a default to other compression variables, 307 such as 'core.loosecompression' and 'pack.compression'. 308 309core.loosecompression:: 310 An integer -1..9, indicating the compression level for objects that 311 are not in a pack file. -1 is the zlib default. 0 means no 312 compression, and 1..9 are various speed/size tradeoffs, 9 being 313 slowest. If not set, defaults to core.compression. If that is 314 not set, defaults to 1 (best speed). 315 316core.packedGitWindowSize:: 317 Number of bytes of a pack file to map into memory in a 318 single mapping operation. Larger window sizes may allow 319 your system to process a smaller number of large pack files 320 more quickly. Smaller window sizes will negatively affect 321 performance due to increased calls to the operating system's 322 memory manager, but may improve performance when accessing 323 a large number of large pack files. 324+ 325Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32 326MiB on 32 bit platforms and 1 GiB on 64 bit platforms. This should 327be reasonable for all users/operating systems. You probably do 328not need to adjust this value. 329+ 330Common unit suffixes of 'k', 'm', or 'g' are supported. 331 332core.packedGitLimit:: 333 Maximum number of bytes to map simultaneously into memory 334 from pack files. If Git needs to access more than this many 335 bytes at once to complete an operation it will unmap existing 336 regions to reclaim virtual address space within the process. 337+ 338Default is 256 MiB on 32 bit platforms and 8 GiB on 64 bit platforms. 339This should be reasonable for all users/operating systems, except on 340the largest projects. You probably do not need to adjust this value. 341+ 342Common unit suffixes of 'k', 'm', or 'g' are supported. 343 344core.deltaBaseCacheLimit:: 345 Maximum number of bytes to reserve for caching base objects 346 that multiple deltafied objects reference. By storing the 347 entire decompressed base objects in a cache Git is able 348 to avoid unpacking and decompressing frequently used base 349 objects multiple times. 350+ 351Default is 16 MiB on all platforms. This should be reasonable 352for all users/operating systems, except on the largest projects. 353You probably do not need to adjust this value. 354+ 355Common unit suffixes of 'k', 'm', or 'g' are supported. 356 357core.excludesfile:: 358 In addition to '.gitignore' (per-directory) and 359 '.git/info/exclude', git looks into this file for patterns 360 of files which are not meant to be tracked. See 361 linkgit:gitignore[5]. 362 363core.editor:: 364 Commands such as `commit` and `tag` that lets you edit 365 messages by launching an editor uses the value of this 366 variable when it is set, and the environment variable 367 `GIT_EDITOR` is not set. The order of preference is 368 `GIT_EDITOR` environment, `core.editor`, `VISUAL` and 369 `EDITOR` environment variables and then finally `vi`. 370 371core.pager:: 372 The command that git will use to paginate output. Can 373 be overridden with the `GIT_PAGER` environment 374 variable. Note that git sets the `LESS` environment 375 variable to `FRSX` if it is unset when it runs the 376 pager. One can change these settings by setting the 377 `LESS` variable to some other value. Alternately, 378 these settings can be overridden on a project or 379 global basis by setting the `core.pager` option. 380 Setting `core.pager` has no affect on the `LESS` 381 environment variable behaviour above, so if you want 382 to override git's default settings this way, you need 383 to be explicit. For example, to disable the S option 384 in a backward compatible manner, set `core.pager` 385 to "`less -+$LESS -FRX`". This will be passed to the 386 shell by git, which will translate the final command to 387 "`LESS=FRSX less -+FRSX -FRX`". 388 389core.whitespace:: 390 A comma separated list of common whitespace problems to 391 notice. 'git-diff' will use `color.diff.whitespace` to 392 highlight them, and 'git-apply --whitespace=error' will 393 consider them as errors. You can prefix `-` to disable 394 any of them (e.g. `-trailing-space`): 395+ 396* `trailing-space` treats trailing whitespaces at the end of the line 397 as an error (enabled by default). 398* `space-before-tab` treats a space character that appears immediately 399 before a tab character in the initial indent part of the line as an 400 error (enabled by default). 401* `indent-with-non-tab` treats a line that is indented with 8 or more 402 space characters as an error (not enabled by default). 403* `cr-at-eol` treats a carriage-return at the end of line as 404 part of the line terminator, i.e. with it, `trailing-space` 405 does not trigger if the character before such a carriage-return 406 is not a whitespace (not enabled by default). 407 408core.fsyncobjectfiles:: 409 This boolean will enable 'fsync()' when writing object files. 410+ 411This is a total waste of time and effort on a filesystem that orders 412data writes properly, but can be useful for filesystems that do not use 413journalling (traditional UNIX filesystems) or that only journal metadata 414and not file contents (OS X's HFS+, or Linux ext3 with "data=writeback"). 415 416core.preloadindex:: 417 Enable parallel index preload for operations like 'git diff' 418+ 419This can speed up operations like 'git diff' and 'git status' especially 420on filesystems like NFS that have weak caching semantics and thus 421relatively high IO latencies. With this set to 'true', git will do the 422index comparison to the filesystem data in parallel, allowing 423overlapping IO's. 424 425alias.*:: 426 Command aliases for the linkgit:git[1] command wrapper - e.g. 427 after defining "alias.last = cat-file commit HEAD", the invocation 428 "git last" is equivalent to "git cat-file commit HEAD". To avoid 429 confusion and troubles with script usage, aliases that 430 hide existing git commands are ignored. Arguments are split by 431 spaces, the usual shell quoting and escaping is supported. 432 quote pair and a backslash can be used to quote them. 433+ 434If the alias expansion is prefixed with an exclamation point, 435it will be treated as a shell command. For example, defining 436"alias.new = !gitk --all --not ORIG_HEAD", the invocation 437"git new" is equivalent to running the shell command 438"gitk --all --not ORIG_HEAD". 439 440apply.whitespace:: 441 Tells 'git-apply' how to handle whitespaces, in the same way 442 as the '--whitespace' option. See linkgit:git-apply[1]. 443 444branch.autosetupmerge:: 445 Tells 'git-branch' and 'git-checkout' to setup new branches 446 so that linkgit:git-pull[1] will appropriately merge from the 447 starting point branch. Note that even if this option is not set, 448 this behavior can be chosen per-branch using the `--track` 449 and `--no-track` options. The valid settings are: `false` -- no 450 automatic setup is done; `true` -- automatic setup is done when the 451 starting point is a remote branch; `always` -- automatic setup is 452 done when the starting point is either a local branch or remote 453 branch. This option defaults to true. 454 455branch.autosetuprebase:: 456 When a new branch is created with 'git-branch' or 'git-checkout' 457 that tracks another branch, this variable tells git to set 458 up pull to rebase instead of merge (see "branch.<name>.rebase"). 459 When `never`, rebase is never automatically set to true. 460 When `local`, rebase is set to true for tracked branches of 461 other local branches. 462 When `remote`, rebase is set to true for tracked branches of 463 remote branches. 464 When `always`, rebase will be set to true for all tracking 465 branches. 466 See "branch.autosetupmerge" for details on how to set up a 467 branch to track another branch. 468 This option defaults to never. 469 470branch.<name>.remote:: 471 When in branch <name>, it tells 'git-fetch' which remote to fetch. 472 If this option is not given, 'git-fetch' defaults to remote "origin". 473 474branch.<name>.merge:: 475 When in branch <name>, it tells 'git-fetch' the default 476 refspec to be marked for merging in FETCH_HEAD. The value is 477 handled like the remote part of a refspec, and must match a 478 ref which is fetched from the remote given by 479 "branch.<name>.remote". 480 The merge information is used by 'git-pull' (which at first calls 481 'git-fetch') to lookup the default branch for merging. Without 482 this option, 'git-pull' defaults to merge the first refspec fetched. 483 Specify multiple values to get an octopus merge. 484 If you wish to setup 'git-pull' so that it merges into <name> from 485 another branch in the local repository, you can point 486 branch.<name>.merge to the desired branch, and use the special setting 487 `.` (a period) for branch.<name>.remote. 488 489branch.<name>.mergeoptions:: 490 Sets default options for merging into branch <name>. The syntax and 491 supported options are equal to that of linkgit:git-merge[1], but 492 option values containing whitespace characters are currently not 493 supported. 494 495branch.<name>.rebase:: 496 When true, rebase the branch <name> on top of the fetched branch, 497 instead of merging the default branch from the default remote when 498 "git pull" is run. 499 *NOTE*: this is a possibly dangerous operation; do *not* use 500 it unless you understand the implications (see linkgit:git-rebase[1] 501 for details). 502 503browser.<tool>.cmd:: 504 Specify the command to invoke the specified browser. The 505 specified command is evaluated in shell with the URLs passed 506 as arguments. (See linkgit:git-web--browse[1].) 507 508browser.<tool>.path:: 509 Override the path for the given tool that may be used to 510 browse HTML help (see '-w' option in linkgit:git-help[1]) or a 511 working repository in gitweb (see linkgit:git-instaweb[1]). 512 513clean.requireForce:: 514 A boolean to make git-clean do nothing unless given -f 515 or -n. Defaults to true. 516 517color.branch:: 518 A boolean to enable/disable color in the output of 519 linkgit:git-branch[1]. May be set to `always`, 520 `false` (or `never`) or `auto` (or `true`), in which case colors are used 521 only when the output is to a terminal. Defaults to false. 522 523color.branch.<slot>:: 524 Use customized color for branch coloration. `<slot>` is one of 525 `current` (the current branch), `local` (a local branch), 526 `remote` (a tracking branch in refs/remotes/), `plain` (other 527 refs). 528+ 529The value for these configuration variables is a list of colors (at most 530two) and attributes (at most one), separated by spaces. The colors 531accepted are `normal`, `black`, `red`, `green`, `yellow`, `blue`, 532`magenta`, `cyan` and `white`; the attributes are `bold`, `dim`, `ul`, 533`blink` and `reverse`. The first color given is the foreground; the 534second is the background. The position of the attribute, if any, 535doesn't matter. 536 537color.diff:: 538 When set to `always`, always use colors in patch. 539 When false (or `never`), never. When set to `true` or `auto`, use 540 colors only when the output is to the terminal. Defaults to false. 541 542color.diff.<slot>:: 543 Use customized color for diff colorization. `<slot>` specifies 544 which part of the patch to use the specified color, and is one 545 of `plain` (context text), `meta` (metainformation), `frag` 546 (hunk header), `old` (removed lines), `new` (added lines), 547 `commit` (commit headers), or `whitespace` (highlighting 548 whitespace errors). The values of these variables may be specified as 549 in color.branch.<slot>. 550 551color.interactive:: 552 When set to `always`, always use colors for interactive prompts 553 and displays (such as those used by "git-add --interactive"). 554 When false (or `never`), never. When set to `true` or `auto`, use 555 colors only when the output is to the terminal. Defaults to false. 556 557color.interactive.<slot>:: 558 Use customized color for 'git-add --interactive' 559 output. `<slot>` may be `prompt`, `header`, or `help`, for 560 three distinct types of normal output from interactive 561 programs. The values of these variables may be specified as 562 in color.branch.<slot>. 563 564color.pager:: 565 A boolean to enable/disable colored output when the pager is in 566 use (default is true). 567 568color.status:: 569 A boolean to enable/disable color in the output of 570 linkgit:git-status[1]. May be set to `always`, 571 `false` (or `never`) or `auto` (or `true`), in which case colors are used 572 only when the output is to a terminal. Defaults to false. 573 574color.status.<slot>:: 575 Use customized color for status colorization. `<slot>` is 576 one of `header` (the header text of the status message), 577 `added` or `updated` (files which are added but not committed), 578 `changed` (files which are changed but not added in the index), 579 `untracked` (files which are not tracked by git), or 580 `nobranch` (the color the 'no branch' warning is shown in, defaulting 581 to red). The values of these variables may be specified as in 582 color.branch.<slot>. 583 584color.ui:: 585 When set to `always`, always use colors in all git commands which 586 are capable of colored output. When false (or `never`), never. When 587 set to `true` or `auto`, use colors only when the output is to the 588 terminal. When more specific variables of color.* are set, they always 589 take precedence over this setting. Defaults to false. 590 591commit.template:: 592 Specify a file to use as the template for new commit messages. 593 594diff.autorefreshindex:: 595 When using 'git-diff' to compare with work tree 596 files, do not consider stat-only change as changed. 597 Instead, silently run `git update-index --refresh` to 598 update the cached stat information for paths whose 599 contents in the work tree match the contents in the 600 index. This option defaults to true. Note that this 601 affects only 'git-diff' Porcelain, and not lower level 602 'diff' commands, such as 'git-diff-files'. 603 604diff.suppress-blank-empty:: 605 A boolean to inhibit the standard behavior of printing a space 606 before each empty output line. Defaults to false. 607 608diff.external:: 609 If this config variable is set, diff generation is not 610 performed using the internal diff machinery, but using the 611 given command. Can be overridden with the `GIT_EXTERNAL_DIFF' 612 environment variable. The command is called with parameters 613 as described under "git Diffs" in linkgit:git[1]. Note: if 614 you want to use an external diff program only on a subset of 615 your files, you might want to use linkgit:gitattributes[5] instead. 616 617diff.mnemonicprefix:: 618 If set, 'git-diff' uses a prefix pair that is different from the 619 standard "a/" and "b/" depending on what is being compared. When 620 this configuration is in effect, reverse diff output also swaps 621 the order of the prefixes: 622'git-diff';; 623 compares the (i)ndex and the (w)ork tree; 624'git-diff HEAD';; 625 compares a (c)ommit and the (w)ork tree; 626'git diff --cached';; 627 compares a (c)ommit and the (i)ndex; 628'git-diff HEAD:file1 file2';; 629 compares an (o)bject and a (w)ork tree entity; 630'git diff --no-index a b';; 631 compares two non-git things (1) and (2). 632 633diff.renameLimit:: 634 The number of files to consider when performing the copy/rename 635 detection; equivalent to the 'git-diff' option '-l'. 636 637diff.renames:: 638 Tells git to detect renames. If set to any boolean value, it 639 will enable basic rename detection. If set to "copies" or 640 "copy", it will detect copies, as well. 641 642fetch.unpackLimit:: 643 If the number of objects fetched over the git native 644 transfer is below this 645 limit, then the objects will be unpacked into loose object 646 files. However if the number of received objects equals or 647 exceeds this limit then the received pack will be stored as 648 a pack, after adding any missing delta bases. Storing the 649 pack from a push can make the push operation complete faster, 650 especially on slow filesystems. If not set, the value of 651 `transfer.unpackLimit` is used instead. 652 653format.numbered:: 654 A boolean which can enable or disable sequence numbers in patch 655 subjects. It defaults to "auto" which enables it only if there 656 is more than one patch. It can be enabled or disabled for all 657 messages by setting it to "true" or "false". See --numbered 658 option in linkgit:git-format-patch[1]. 659 660format.headers:: 661 Additional email headers to include in a patch to be submitted 662 by mail. See linkgit:git-format-patch[1]. 663 664format.suffix:: 665 The default for format-patch is to output files with the suffix 666 `.patch`. Use this variable to change that suffix (make sure to 667 include the dot if you want it). 668 669format.pretty:: 670 The default pretty format for log/show/whatchanged command, 671 See linkgit:git-log[1], linkgit:git-show[1], 672 linkgit:git-whatchanged[1]. 673 674gc.aggressiveWindow:: 675 The window size parameter used in the delta compression 676 algorithm used by 'git-gc --aggressive'. This defaults 677 to 10. 678 679gc.auto:: 680 When there are approximately more than this many loose 681 objects in the repository, `git gc --auto` will pack them. 682 Some Porcelain commands use this command to perform a 683 light-weight garbage collection from time to time. The 684 default value is 6700. Setting this to 0 disables it. 685 686gc.autopacklimit:: 687 When there are more than this many packs that are not 688 marked with `*.keep` file in the repository, `git gc 689 --auto` consolidates them into one larger pack. The 690 default value is 50. Setting this to 0 disables it. 691 692gc.packrefs:: 693 'git-gc' does not run `git pack-refs` in a bare repository by 694 default so that older dumb-transport clients can still fetch 695 from the repository. Setting this to `true` lets 'git-gc' 696 to run `git pack-refs`. Setting this to `false` tells 697 'git-gc' never to run `git pack-refs`. The default setting is 698 `notbare`. Enable it only when you know you do not have to 699 support such clients. The default setting will change to `true` 700 at some stage, and setting this to `false` will continue to 701 prevent `git pack-refs` from being run from 'git-gc'. 702 703gc.pruneexpire:: 704 When 'git-gc' is run, it will call 'prune --expire 2.weeks.ago'. 705 Override the grace period with this config variable. 706 707gc.reflogexpire:: 708 'git-reflog expire' removes reflog entries older than 709 this time; defaults to 90 days. 710 711gc.reflogexpireunreachable:: 712 'git-reflog expire' removes reflog entries older than 713 this time and are not reachable from the current tip; 714 defaults to 30 days. 715 716gc.rerereresolved:: 717 Records of conflicted merge you resolved earlier are 718 kept for this many days when 'git-rerere gc' is run. 719 The default is 60 days. See linkgit:git-rerere[1]. 720 721gc.rerereunresolved:: 722 Records of conflicted merge you have not resolved are 723 kept for this many days when 'git-rerere gc' is run. 724 The default is 15 days. See linkgit:git-rerere[1]. 725 726gitcvs.enabled:: 727 Whether the CVS server interface is enabled for this repository. 728 See linkgit:git-cvsserver[1]. 729 730gitcvs.logfile:: 731 Path to a log file where the CVS server interface well... logs 732 various stuff. See linkgit:git-cvsserver[1]. 733 734gitcvs.usecrlfattr:: 735 If true, the server will look up the `crlf` attribute for 736 files to determine the '-k' modes to use. If `crlf` is set, 737 the '-k' mode will be left blank, so cvs clients will 738 treat it as text. If `crlf` is explicitly unset, the file 739 will be set with '-kb' mode, which suppresses any newline munging 740 the client might otherwise do. If `crlf` is not specified, 741 then 'gitcvs.allbinary' is used. See linkgit:gitattributes[5]. 742 743gitcvs.allbinary:: 744 This is used if 'gitcvs.usecrlfattr' does not resolve 745 the correct '-kb' mode to use. If true, all 746 unresolved files are sent to the client in 747 mode '-kb'. This causes the client to treat them 748 as binary files, which suppresses any newline munging it 749 otherwise might do. Alternatively, if it is set to "guess", 750 then the contents of the file are examined to decide if 751 it is binary, similar to 'core.autocrlf'. 752 753gitcvs.dbname:: 754 Database used by git-cvsserver to cache revision information 755 derived from the git repository. The exact meaning depends on the 756 used database driver, for SQLite (which is the default driver) this 757 is a filename. Supports variable substitution (see 758 linkgit:git-cvsserver[1] for details). May not contain semicolons (`;`). 759 Default: '%Ggitcvs.%m.sqlite' 760 761gitcvs.dbdriver:: 762 Used Perl DBI driver. You can specify any available driver 763 for this here, but it might not work. git-cvsserver is tested 764 with 'DBD::SQLite', reported to work with 'DBD::Pg', and 765 reported *not* to work with 'DBD::mysql'. Experimental feature. 766 May not contain double colons (`:`). Default: 'SQLite'. 767 See linkgit:git-cvsserver[1]. 768 769gitcvs.dbuser, gitcvs.dbpass:: 770 Database user and password. Only useful if setting 'gitcvs.dbdriver', 771 since SQLite has no concept of database users and/or passwords. 772 'gitcvs.dbuser' supports variable substitution (see 773 linkgit:git-cvsserver[1] for details). 774 775gitcvs.dbTableNamePrefix:: 776 Database table name prefix. Prepended to the names of any 777 database tables used, allowing a single database to be used 778 for several repositories. Supports variable substitution (see 779 linkgit:git-cvsserver[1] for details). Any non-alphabetic 780 characters will be replaced with underscores. 781 782All gitcvs variables except for 'gitcvs.usecrlfattr' and 783'gitcvs.allbinary' can also be specified as 784'gitcvs.<access_method>.<varname>' (where 'access_method' 785is one of "ext" and "pserver") to make them apply only for the given 786access method. 787 788gui.commitmsgwidth:: 789 Defines how wide the commit message window is in the 790 linkgit:git-gui[1]. "75" is the default. 791 792gui.diffcontext:: 793 Specifies how many context lines should be used in calls to diff 794 made by the linkgit:git-gui[1]. The default is "5". 795 796gui.encoding:: 797 Specifies the default encoding to use for displaying of 798 file contents in linkgit:git-gui[1] and linkgit:gitk[1]. 799 It can be overridden by setting the 'encoding' attribute 800 for relevant files (see linkgit:gitattributes[5]). 801 If this option is not set, the tools default to the 802 locale encoding. 803 804gui.matchtrackingbranch:: 805 Determines if new branches created with linkgit:git-gui[1] should 806 default to tracking remote branches with matching names or 807 not. Default: "false". 808 809gui.newbranchtemplate:: 810 Is used as suggested name when creating new branches using the 811 linkgit:git-gui[1]. 812 813gui.pruneduringfetch:: 814 "true" if linkgit:git-gui[1] should prune tracking branches when 815 performing a fetch. The default value is "false". 816 817gui.trustmtime:: 818 Determines if linkgit:git-gui[1] should trust the file modification 819 timestamp or not. By default the timestamps are not trusted. 820 821gui.spellingdictionary:: 822 Specifies the dictionary used for spell checking commit messages in 823 the linkgit:git-gui[1]. When set to "none" spell checking is turned 824 off. 825 826gui.fastcopyblame:: 827 If true, 'git gui blame' uses '-C' instead of '-C -C' for original 828 location detection. It makes blame significantly faster on huge 829 repositories at the expense of less thorough copy detection. 830 831gui.copyblamethreshold:: 832 Specifies the threshold to use in 'git gui blame' original location 833 detection, measured in alphanumeric characters. See the 834 linkgit:git-blame[1] manual for more information on copy detection. 835 836gui.blamehistoryctx:: 837 Specifies the radius of history context in days to show in 838 linkgit:gitk[1] for the selected commit, when the `Show History 839 Context` menu item is invoked from 'git gui blame'. If this 840 variable is set to zero, the whole history is shown. 841 842help.browser:: 843 Specify the browser that will be used to display help in the 844 'web' format. See linkgit:git-help[1]. 845 846help.format:: 847 Override the default help format used by linkgit:git-help[1]. 848 Values 'man', 'info', 'web' and 'html' are supported. 'man' is 849 the default. 'web' and 'html' are the same. 850 851help.autocorrect:: 852 Automatically correct and execute mistyped commands after 853 waiting for the given number of deciseconds (0.1 sec). If more 854 than one command can be deduced from the entered text, nothing 855 will be executed. If the value of this option is negative, 856 the corrected command will be executed immediately. If the 857 value is 0 - the command will be just shown but not executed. 858 This is the default. 859 860http.proxy:: 861 Override the HTTP proxy, normally configured using the 'http_proxy' 862 environment variable (see linkgit:curl[1]). This can be overridden 863 on a per-remote basis; see remote.<name>.proxy 864 865http.sslVerify:: 866 Whether to verify the SSL certificate when fetching or pushing 867 over HTTPS. Can be overridden by the 'GIT_SSL_NO_VERIFY' environment 868 variable. 869 870http.sslCert:: 871 File containing the SSL certificate when fetching or pushing 872 over HTTPS. Can be overridden by the 'GIT_SSL_CERT' environment 873 variable. 874 875http.sslKey:: 876 File containing the SSL private key when fetching or pushing 877 over HTTPS. Can be overridden by the 'GIT_SSL_KEY' environment 878 variable. 879 880http.sslCAInfo:: 881 File containing the certificates to verify the peer with when 882 fetching or pushing over HTTPS. Can be overridden by the 883 'GIT_SSL_CAINFO' environment variable. 884 885http.sslCAPath:: 886 Path containing files with the CA certificates to verify the peer 887 with when fetching or pushing over HTTPS. Can be overridden 888 by the 'GIT_SSL_CAPATH' environment variable. 889 890http.maxRequests:: 891 How many HTTP requests to launch in parallel. Can be overridden 892 by the 'GIT_HTTP_MAX_REQUESTS' environment variable. Default is 5. 893 894http.lowSpeedLimit, http.lowSpeedTime:: 895 If the HTTP transfer speed is less than 'http.lowSpeedLimit' 896 for longer than 'http.lowSpeedTime' seconds, the transfer is aborted. 897 Can be overridden by the 'GIT_HTTP_LOW_SPEED_LIMIT' and 898 'GIT_HTTP_LOW_SPEED_TIME' environment variables. 899 900http.noEPSV:: 901 A boolean which disables using of EPSV ftp command by curl. 902 This can helpful with some "poor" ftp servers which don't 903 support EPSV mode. Can be overridden by the 'GIT_CURL_FTP_NO_EPSV' 904 environment variable. Default is false (curl will use EPSV). 905 906i18n.commitEncoding:: 907 Character encoding the commit messages are stored in; git itself 908 does not care per se, but this information is necessary e.g. when 909 importing commits from emails or in the gitk graphical history 910 browser (and possibly at other places in the future or in other 911 porcelains). See e.g. linkgit:git-mailinfo[1]. Defaults to 'utf-8'. 912 913i18n.logOutputEncoding:: 914 Character encoding the commit messages are converted to when 915 running 'git-log' and friends. 916 917imap:: 918 The configuration variables in the 'imap' section are described 919 in linkgit:git-imap-send[1]. 920 921instaweb.browser:: 922 Specify the program that will be used to browse your working 923 repository in gitweb. See linkgit:git-instaweb[1]. 924 925instaweb.httpd:: 926 The HTTP daemon command-line to start gitweb on your working 927 repository. See linkgit:git-instaweb[1]. 928 929instaweb.local:: 930 If true the web server started by linkgit:git-instaweb[1] will 931 be bound to the local IP (127.0.0.1). 932 933instaweb.modulepath:: 934 The module path for an apache httpd used by linkgit:git-instaweb[1]. 935 936instaweb.port:: 937 The port number to bind the gitweb httpd to. See 938 linkgit:git-instaweb[1]. 939 940log.date:: 941 Set default date-time mode for the log command. Setting log.date 942 value is similar to using 'git-log'\'s --date option. The value is one of the 943 following alternatives: {relative,local,default,iso,rfc,short}. 944 See linkgit:git-log[1]. 945 946log.showroot:: 947 If true, the initial commit will be shown as a big creation event. 948 This is equivalent to a diff against an empty tree. 949 Tools like linkgit:git-log[1] or linkgit:git-whatchanged[1], which 950 normally hide the root commit will now show it. True by default. 951 952man.viewer:: 953 Specify the programs that may be used to display help in the 954 'man' format. See linkgit:git-help[1]. 955 956man.<tool>.cmd:: 957 Specify the command to invoke the specified man viewer. The 958 specified command is evaluated in shell with the man page 959 passed as argument. (See linkgit:git-help[1].) 960 961man.<tool>.path:: 962 Override the path for the given tool that may be used to 963 display help in the 'man' format. See linkgit:git-help[1]. 964 965include::merge-config.txt[] 966 967mergetool.<tool>.path:: 968 Override the path for the given tool. This is useful in case 969 your tool is not in the PATH. 970 971mergetool.<tool>.cmd:: 972 Specify the command to invoke the specified merge tool. The 973 specified command is evaluated in shell with the following 974 variables available: 'BASE' is the name of a temporary file 975 containing the common base of the files to be merged, if available; 976 'LOCAL' is the name of a temporary file containing the contents of 977 the file on the current branch; 'REMOTE' is the name of a temporary 978 file containing the contents of the file from the branch being 979 merged; 'MERGED' contains the name of the file to which the merge 980 tool should write the results of a successful merge. 981 982mergetool.<tool>.trustExitCode:: 983 For a custom merge command, specify whether the exit code of 984 the merge command can be used to determine whether the merge was 985 successful. If this is not set to true then the merge target file 986 timestamp is checked and the merge assumed to have been successful 987 if the file has been updated, otherwise the user is prompted to 988 indicate the success of the merge. 989 990mergetool.keepBackup:: 991 After performing a merge, the original file with conflict markers 992 can be saved as a file with a `.orig` extension. If this variable 993 is set to `false` then this file is not preserved. Defaults to 994 `true` (i.e. keep the backup files). 995 996pack.window:: 997 The size of the window used by linkgit:git-pack-objects[1] when no 998 window size is given on the command line. Defaults to 10. 9991000pack.depth::1001 The maximum delta depth used by linkgit:git-pack-objects[1] when no1002 maximum depth is given on the command line. Defaults to 50.10031004pack.windowMemory::1005 The window memory size limit used by linkgit:git-pack-objects[1]1006 when no limit is given on the command line. The value can be1007 suffixed with "k", "m", or "g". Defaults to 0, meaning no1008 limit.10091010pack.compression::1011 An integer -1..9, indicating the compression level for objects1012 in a pack file. -1 is the zlib default. 0 means no1013 compression, and 1..9 are various speed/size tradeoffs, 9 being1014 slowest. If not set, defaults to core.compression. If that is1015 not set, defaults to -1, the zlib default, which is "a default1016 compromise between speed and compression (currently equivalent1017 to level 6)."10181019pack.deltaCacheSize::1020 The maximum memory in bytes used for caching deltas in1021 linkgit:git-pack-objects[1].1022 A value of 0 means no limit. Defaults to 0.10231024pack.deltaCacheLimit::1025 The maximum size of a delta, that is cached in1026 linkgit:git-pack-objects[1]. Defaults to 1000.10271028pack.threads::1029 Specifies the number of threads to spawn when searching for best1030 delta matches. This requires that linkgit:git-pack-objects[1]1031 be compiled with pthreads otherwise this option is ignored with a1032 warning. This is meant to reduce packing time on multiprocessor1033 machines. The required amount of memory for the delta search window1034 is however multiplied by the number of threads.1035 Specifying 0 will cause git to auto-detect the number of CPU's1036 and set the number of threads accordingly.10371038pack.indexVersion::1039 Specify the default pack index version. Valid values are 1 for1040 legacy pack index used by Git versions prior to 1.5.2, and 2 for1041 the new pack index with capabilities for packs larger than 4 GB1042 as well as proper protection against the repacking of corrupted1043 packs. Version 2 is the default. Note that version 2 is enforced1044 and this config option ignored whenever the corresponding pack is1045 larger than 2 GB.1046+1047If you have an old git that does not understand the version 2 `{asterisk}.idx` file,1048cloning or fetching over a non native protocol (e.g. "http" and "rsync")1049that will copy both `{asterisk}.pack` file and corresponding `{asterisk}.idx` file from the1050other side may give you a repository that cannot be accessed with your1051older version of git. If the `{asterisk}.pack` file is smaller than 2 GB, however,1052you can use linkgit:git-index-pack[1] on the *.pack file to regenerate1053the `{asterisk}.idx` file.10541055pack.packSizeLimit::1056 The default maximum size of a pack. This setting only affects1057 packing to a file, i.e. the git:// protocol is unaffected. It1058 can be overridden by the `\--max-pack-size` option of1059 linkgit:git-repack[1].10601061pager.<cmd>::1062 Allows turning on or off pagination of the output of a1063 particular git subcommand when writing to a tty. If1064 `\--paginate` or `\--no-pager` is specified on the command line,1065 it takes precedence over this option. To disable pagination for1066 all commands, set `core.pager` or 'GIT_PAGER' to "`cat`".10671068pull.octopus::1069 The default merge strategy to use when pulling multiple branches1070 at once.10711072pull.twohead::1073 The default merge strategy to use when pulling a single branch.10741075receive.fsckObjects::1076 If it is set to true, git-receive-pack will check all received1077 objects. It will abort in the case of a malformed object or a1078 broken link. The result of an abort are only dangling objects.1079 Defaults to false.10801081receive.unpackLimit::1082 If the number of objects received in a push is below this1083 limit then the objects will be unpacked into loose object1084 files. However if the number of received objects equals or1085 exceeds this limit then the received pack will be stored as1086 a pack, after adding any missing delta bases. Storing the1087 pack from a push can make the push operation complete faster,1088 especially on slow filesystems. If not set, the value of1089 `transfer.unpackLimit` is used instead.10901091receive.denyDeletes::1092 If set to true, git-receive-pack will deny a ref update that deletes1093 the ref. Use this to prevent such a ref deletion via a push.10941095receive.denyCurrentBranch::1096 If set to true or "refuse", receive-pack will deny a ref update1097 to the currently checked out branch of a non-bare repository.1098 Such a push is potentially dangerous because it brings the HEAD1099 out of sync with the index and working tree. If set to "warn",1100 print a warning of such a push to stderr, but allow the push to1101 proceed. If set to false or "ignore", allow such pushes with no1102 message. Defaults to "warn".11031104receive.denyNonFastForwards::1105 If set to true, git-receive-pack will deny a ref update which is1106 not a fast forward. Use this to prevent such an update via a push,1107 even if that push is forced. This configuration variable is1108 set when initializing a shared repository.11091110remote.<name>.url::1111 The URL of a remote repository. See linkgit:git-fetch[1] or1112 linkgit:git-push[1].11131114remote.<name>.proxy::1115 For remotes that require curl (http, https and ftp), the URL to1116 the proxy to use for that remote. Set to the empty string to1117 disable proxying for that remote.11181119remote.<name>.fetch::1120 The default set of "refspec" for linkgit:git-fetch[1]. See1121 linkgit:git-fetch[1].11221123remote.<name>.push::1124 The default set of "refspec" for linkgit:git-push[1]. See1125 linkgit:git-push[1].11261127remote.<name>.mirror::1128 If true, pushing to this remote will automatically behave1129 as if the `\--mirror` option was given on the command line.11301131remote.<name>.skipDefaultUpdate::1132 If true, this remote will be skipped by default when updating1133 using the update subcommand of linkgit:git-remote[1].11341135remote.<name>.receivepack::1136 The default program to execute on the remote side when pushing. See1137 option \--receive-pack of linkgit:git-push[1].11381139remote.<name>.uploadpack::1140 The default program to execute on the remote side when fetching. See1141 option \--upload-pack of linkgit:git-fetch-pack[1].11421143remote.<name>.tagopt::1144 Setting this value to \--no-tags disables automatic tag following when1145 fetching from remote <name>11461147remotes.<group>::1148 The list of remotes which are fetched by "git remote update1149 <group>". See linkgit:git-remote[1].11501151repack.usedeltabaseoffset::1152 By default, linkgit:git-repack[1] creates packs that use1153 delta-base offset. If you need to share your repository with1154 git older than version 1.4.4, either directly or via a dumb1155 protocol such as http, then you need to set this option to1156 "false" and repack. Access from old git versions over the1157 native protocol are unaffected by this option.11581159rerere.autoupdate::1160 When set to true, `git-rerere` updates the index with the1161 resulting contents after it cleanly resolves conflicts using1162 previously recorded resolution. Defaults to false.11631164rerere.enabled::1165 Activate recording of resolved conflicts, so that identical1166 conflict hunks can be resolved automatically, should they1167 be encountered again. linkgit:git-rerere[1] command is by1168 default enabled if you create `rr-cache` directory under1169 `$GIT_DIR`, but can be disabled by setting this option to false.11701171showbranch.default::1172 The default set of branches for linkgit:git-show-branch[1].1173 See linkgit:git-show-branch[1].11741175status.relativePaths::1176 By default, linkgit:git-status[1] shows paths relative to the1177 current directory. Setting this variable to `false` shows paths1178 relative to the repository root (this was the default for git1179 prior to v1.5.4).11801181status.showUntrackedFiles::1182 By default, linkgit:git-status[1] and linkgit:git-commit[1] show1183 files which are not currently tracked by Git. Directories which1184 contain only untracked files, are shown with the directory name1185 only. Showing untracked files means that Git needs to lstat() all1186 all the files in the whole repository, which might be slow on some1187 systems. So, this variable controls how the commands displays1188 the untracked files. Possible values are:1189+1190--1191 - 'no' - Show no untracked files1192 - 'normal' - Shows untracked files and directories1193 - 'all' - Shows also individual files in untracked directories.1194--1195+1196If this variable is not specified, it defaults to 'normal'.1197This variable can be overridden with the -u|--untracked-files option1198of linkgit:git-status[1] and linkgit:git-commit[1].11991200tar.umask::1201 This variable can be used to restrict the permission bits of1202 tar archive entries. The default is 0002, which turns off the1203 world write bit. The special value "user" indicates that the1204 archiving user's umask will be used instead. See umask(2) and1205 linkgit:git-archive[1].12061207transfer.unpackLimit::1208 When `fetch.unpackLimit` or `receive.unpackLimit` are1209 not set, the value of this variable is used instead.1210 The default value is 100.12111212url.<base>.insteadOf::1213 Any URL that starts with this value will be rewritten to1214 start, instead, with <base>. In cases where some site serves a1215 large number of repositories, and serves them with multiple1216 access methods, and some users need to use different access1217 methods, this feature allows people to specify any of the1218 equivalent URLs and have git automatically rewrite the URL to1219 the best alternative for the particular user, even for a1220 never-before-seen repository on the site. When more than one1221 insteadOf strings match a given URL, the longest match is used.12221223user.email::1224 Your email address to be recorded in any newly created commits.1225 Can be overridden by the 'GIT_AUTHOR_EMAIL', 'GIT_COMMITTER_EMAIL', and1226 'EMAIL' environment variables. See linkgit:git-commit-tree[1].12271228user.name::1229 Your full name to be recorded in any newly created commits.1230 Can be overridden by the 'GIT_AUTHOR_NAME' and 'GIT_COMMITTER_NAME'1231 environment variables. See linkgit:git-commit-tree[1].12321233user.signingkey::1234 If linkgit:git-tag[1] is not selecting the key you want it to1235 automatically when creating a signed tag, you can override the1236 default selection with this variable. This option is passed1237 unchanged to gpg's --local-user parameter, so you may specify a key1238 using any method that gpg supports.12391240web.browser::1241 Specify a web browser that may be used by some commands.1242 Currently only linkgit:git-instaweb[1] and linkgit:git-help[1]1243 may use it.
