  16DESCRIPTION
  17-----------
  18This command updates the index using the current content found in
  19the working tree, to prepare the content staged for the next commit.
  20It typically adds the current content of existing paths as a whole,
  21but with some options it can also be used to add content with
  22only part of the changes made to the working tree files applied, or
  23remove paths that do not exist in the working tree anymore.
  24
  25The "index" holds a snapshot of the content of the working tree, and it
  26is this snapshot that is taken as the contents of the next commit.  Thus
  27after making any changes to the working directory, and before running
  28the commit command, you must use the `add` command to add any new or
  29modified files to the index.
  30
  31This command can be performed multiple times before a commit.  It only
  32adds the content of the specified file(s) at the time the add command is
  33run; if you want subsequent changes included in the next commit, then
  34you must run `git add` again to add the new content to the index.
  35
  36The `git status` command can be used to obtain a summary of which
  37files have changes that are staged for the next commit.
  38
  39The `git add` command will not add ignored files by default.  If any
  40ignored files were explicitly specified on the command line, `git add`
  41will fail with a list of ignored files.  Ignored files reached by
  42directory recursion or filename globbing performed by Git (quote your
  43globs before the shell) will be silently ignored.  The 'git add' command can
  44be used to add ignored files with the `-f` (force) option.
  45
  46Please see linkgit:git-commit[1] for alternative ways to add content to a
  47commit.

  50OPTIONS
  51-------
  52<pathspec>...::
  53        Files to add content from.  Fileglobs (e.g. `*.c`) can
  54        be given to add all matching files.  Also a
  55        leading directory name (e.g. `dir` to add `dir/file1`
  56        and `dir/file2`) can be given to update the index to
  57        match the current state of the directory as a whole (e.g.
  58        specifying `dir` will record not just a file `dir/file1`
  59        modified in the working tree, a file `dir/file2` added to
  60        the working tree, but also a file `dir/file3` removed from
  61        the working tree.  Note that older versions of Git used
  62        to ignore removed files; use `--no-all` option if you want
  63        to add modified or new files but ignore removed ones.
  64
  65-n::
  66--dry-run::
  67        Don't actually add the file(s), just show if they exist and/or will
  68        be ignored.
  69
  70-v::
  71--verbose::
  72        Be verbose.
  73
  74-f::
  75--force::
  76        Allow adding otherwise ignored files.
  77
  78-i::
  79--interactive::
  80        Add modified contents in the working tree interactively to
  81        the index. Optional path arguments may be supplied to limit
  82        operation to a subset of the working tree. See ``Interactive
  83        mode'' for details.
  84
  85-p::
  86--patch::
  87        Interactively choose hunks of patch between the index and the
  88        work tree and add them to the index. This gives the user a chance
  89        to review the difference before adding modified contents to the
  90        index.
  91+
  92This effectively runs `add --interactive`, but bypasses the
  93initial command menu and directly jumps to the `patch` subcommand.
  94See ``Interactive mode'' for details.
  95
  96-e, \--edit::
  97        Open the diff vs. the index in an editor and let the user
  98        edit it.  After the editor was closed, adjust the hunk headers
  99        and apply the patch to the index.
 100+
 101The intent of this option is to pick and choose lines of the patch to
 102apply, or even to modify the contents of lines to be staged. This can be
 103quicker and more flexible than using the interactive hunk selector.
 104However, it is easy to confuse oneself and create a patch that does not
 105apply to the index. See EDITING PATCHES below.
 106
 107-u::
 108--update::
 109        Update the index just where it already has an entry matching
 110        <pathspec>.  This removes as well as modifies index entries to
 111        match the working tree, but adds no new files.
 112+
 113If no <pathspec> is given when `-u` option is used, all
 114tracked files in the entire working tree are updated (old versions
 115of Git used to limit the update to the current directory and its
 116subdirectories).
 117
 118-A::
 119--all::
 120--no-ignore-removal::
 121        Update the index not only where the working tree has a file
 122        matching <pathspec> but also where the index already has an
 123        entry.  This adds, modifies, and removes index entries to
 124        match the working tree.
 125+
 126If no <pathspec> is given when `-A` option is used, all
 127files in the entire working tree are updated (old versions
 128of Git used to limit the update to the current directory and its
 129subdirectories).
 130
 131--no-all::
 132--ignore-removal::
 133        Update the index by adding new files that are unknown to the
 134        index and files modified in the working tree, but ignore
 135        files that have been removed from the working tree.  This
 136        option is a no-op when no <pathspec> is used.
 137+
 138This option is primarily to help users who are used to older
 139versions of Git, whose "git add <pathspec>..." was a synonym
 140for "git add --no-all <pathspec>...", i.e. ignored removed files.
 141
 142-N::
 143--intent-to-add::
 144        Record only the fact that the path will be added later. An entry
 145        for the path is placed in the index with no content. This is
 146        useful for, among other things, showing the unstaged content of
 147        such files with `git diff` and committing them with `git commit
 148        -a`.
 149
 150--refresh::
 151        Don't add the file(s), but only refresh their stat()
 152        information in the index.
 153
 154--ignore-errors::
 155        If some files could not be added because of errors indexing
 156        them, do not abort the operation, but continue adding the
 157        others. The command shall still exit with non-zero status.
 158        The configuration variable `add.ignoreErrors` can be set to
 159        true to make this the default behaviour.
 160
 161--ignore-missing::
 162        This option can only be used together with --dry-run. By using
 163        this option the user can check if any of the given files would
 164        be ignored, no matter if they are already present in the work
 165        tree or not.
 166
 167\--::
 168        This option can be used to separate command-line options from
 169        the list of files, (useful when filenames might be mistaken
 170        for command-line options).
 171
 172
 173Configuration
 174-------------
 175
 176The optional configuration variable `core.excludesfile` indicates a path to a
 177file containing patterns of file names to exclude from git-add, similar to
 178$GIT_DIR/info/exclude.  Patterns in the exclude file are used in addition to
 179those in info/exclude.  See linkgit:gitignore[5].
 180
 181
 182EXAMPLES
 183--------
 184
 185* Adds content from all `*.txt` files under `Documentation` directory
 186and its subdirectories:
 187+
 188------------
 189$ git add Documentation/\*.txt
 190------------
 191+
 192Note that the asterisk `*` is quoted from the shell in this
 193example; this lets the command include the files from
 194subdirectories of `Documentation/` directory.
 195
 196* Considers adding content from all git-*.sh scripts:
 197+
 198------------
 199$ git add git-*.sh
 200------------
 201+
 202Because this example lets the shell expand the asterisk (i.e. you are
 203listing the files explicitly), it does not consider
 204`subdir/git-foo.sh`.
 205
 206Interactive mode
 207----------------
 208When the command enters the interactive mode, it shows the
 209output of the 'status' subcommand, and then goes into its
 210interactive command loop.
 211
 212The command loop shows the list of subcommands available, and
 213gives a prompt "What now> ".  In general, when the prompt ends
 214with a single '>', you can pick only one of the choices given
 215and type return, like this:
 216
 217------------
 218    *** Commands ***
 219      1: status       2: update       3: revert       4: add untracked
 220      5: patch        6: diff         7: quit         8: help
 221    What now> 1
 222------------
 223
 224You also could say `s` or `sta` or `status` above as long as the
 225choice is unique.
 226
 227The main command loop has 6 subcommands (plus help and quit).
 228
 229status::
 230
 231   This shows the change between HEAD and index (i.e. what will be
 232   committed if you say `git commit`), and between index and
 233   working tree files (i.e. what you could stage further before
 234   `git commit` using `git add`) for each path.  A sample output
 235   looks like this:
 236+
 237------------
 238              staged     unstaged path
 239     1:       binary      nothing foo.png
 240     2:     +403/-35        +1/-1 git-add--interactive.perl
 241------------
 242+
 243It shows that foo.png has differences from HEAD (but that is
 244binary so line count cannot be shown) and there is no
 245difference between indexed copy and the working tree
 246version (if the working tree version were also different,
 247'binary' would have been shown in place of 'nothing').  The
 248other file, git-add{litdd}interactive.perl, has 403 lines added
 249and 35 lines deleted if you commit what is in the index, but
 250working tree file has further modifications (one addition and
 251one deletion).
 252
 253update::
 254
 255   This shows the status information and issues an "Update>>"
 256   prompt.  When the prompt ends with double '>>', you can
 257   make more than one selection, concatenated with whitespace or
 258   comma.  Also you can say ranges.  E.g. "2-5 7,9" to choose
 259   2,3,4,5,7,9 from the list.  If the second number in a range is
 260   omitted, all remaining patches are taken.  E.g. "7-" to choose
 261   7,8,9 from the list.  You can say '*' to choose everything.
 262+
 263What you chose are then highlighted with '*',
 264like this:
 265+
 266------------
 267           staged     unstaged path
 268  1:       binary      nothing foo.png
 269* 2:     +403/-35        +1/-1 git-add--interactive.perl
 270------------
 271+
 272To remove selection, prefix the input with `-`
 273like this:
 274+
 275------------
 276Update>> -2
 277------------
 278+
 279After making the selection, answer with an empty line to stage the
 280contents of working tree files for selected paths in the index.
 281
 282revert::
 283
 284  This has a very similar UI to 'update', and the staged
 285  information for selected paths are reverted to that of the
 286  HEAD version.  Reverting new paths makes them untracked.
 287
 288add untracked::
 289
 290  This has a very similar UI to 'update' and
 291  'revert', and lets you add untracked paths to the index.
 292
 293patch::
 294
 295  This lets you choose one path out of a 'status' like selection.
 296  After choosing the path, it presents the diff between the index
 297  and the working tree file and asks you if you want to stage
 298  the change of each hunk.  You can select one of the following
 299  options and type return:
 300
 301       y - stage this hunk
 302       n - do not stage this hunk
 303       q - quit; do not stage this hunk or any of the remaining ones
 304       a - stage this hunk and all later hunks in the file
 305       d - do not stage this hunk or any of the later hunks in the file
 306       g - select a hunk to go to
 307       / - search for a hunk matching the given regex
 308       j - leave this hunk undecided, see next undecided hunk
 309       J - leave this hunk undecided, see next hunk
 310       k - leave this hunk undecided, see previous undecided hunk
 311       K - leave this hunk undecided, see previous hunk
 312       s - split the current hunk into smaller hunks
 313       e - manually edit the current hunk
 314       ? - print help
 315+
 316After deciding the fate for all hunks, if there is any hunk
 317that was chosen, the index is updated with the selected hunks.
 318+
 319You can omit having to type return here, by setting the configuration
 320variable `interactive.singlekey` to `true`.
 321
 322diff::
 323
 324  This lets you review what will be committed (i.e. between
 325  HEAD and index).
 326
 327
 328EDITING PATCHES
 329---------------
 330
 331Invoking `git add -e` or selecting `e` from the interactive hunk
 332selector will open a patch in your editor; after the editor exits, the
 333result is applied to the index. You are free to make arbitrary changes
 334to the patch, but note that some changes may have confusing results, or
 335even result in a patch that cannot be applied.  If you want to abort the
 336operation entirely (i.e., stage nothing new in the index), simply delete
 337all lines of the patch. The list below describes some common things you
 338may see in a patch, and which editing operations make sense on them.
 339
 340--
 341added content::
 342
 343Added content is represented by lines beginning with "{plus}". You can
 344prevent staging any addition lines by deleting them.
 345
 346removed content::
 347
 348Removed content is represented by lines beginning with "-". You can
 349prevent staging their removal by converting the "-" to a " " (space).
 350
 351modified content::
 352
 353Modified content is represented by "-" lines (removing the old content)
 354followed by "{plus}" lines (adding the replacement content). You can
 355prevent staging the modification by converting "-" lines to " ", and
 356removing "{plus}" lines. Beware that modifying only half of the pair is
 357likely to introduce confusing changes to the index.
 358--
 359
 360There are also more complex operations that can be performed. But beware
 361that because the patch is applied only to the index and not the working
 362tree, the working tree will appear to "undo" the change in the index.
 363For example, introducing a new line into the index that is in neither
 364the HEAD nor the working tree will stage the new line for commit, but
 365the line will appear to be reverted in the working tree.
 366
 367Avoid using these constructs, or do so with extreme caution.
 368
 369--
 370removing untouched content::
 371
 372Content which does not differ between the index and working tree may be
 373shown on context lines, beginning with a " " (space).  You can stage
 374context lines for removal by converting the space to a "-". The
 375resulting working tree file will appear to re-add the content.
 376
 377modifying existing content::
 378
 379One can also modify context lines by staging them for removal (by
 380converting " " to "-") and adding a "{plus}" line with the new content.
 381Similarly, one can modify "{plus}" lines for existing additions or
 382modifications. In all cases, the new modification will appear reverted
 383in the working tree.
 384
 385new content::
 386
 387You may also add new content that does not exist in the patch; simply
 388add new lines, each starting with "{plus}". The addition will appear
 389reverted in the working tree.
 390--
 391
 392There are also several operations which should be avoided entirely, as
 393they will make the patch impossible to apply:
 394
 395* adding context (" ") or removal ("-") lines
 396* deleting context or removal lines
 397* modifying the contents of context or removal lines
