  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.

  49
  50OPTIONS
  51-------
  52<filepattern>...::
  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 add all files in the
  57        directory, recursively.
  58
  59-n::
  60--dry-run::
  61        Don't actually add the file(s), just show if they exist and/or will
  62        be ignored.
  63
  64-v::
  65--verbose::
  66        Be verbose.
  67
  68-f::
  69--force::
  70        Allow adding otherwise ignored files.
  71
  72-i::
  73--interactive::
  74        Add modified contents in the working tree interactively to
  75        the index. Optional path arguments may be supplied to limit
  76        operation to a subset of the working tree. See ``Interactive
  77        mode'' for details.
  78
  79-p::
  80--patch::
  81        Interactively choose hunks of patch between the index and the
  82        work tree and add them to the index. This gives the user a chance
  83        to review the difference before adding modified contents to the
  84        index.
  85+
  86This effectively runs `add --interactive`, but bypasses the
  87initial command menu and directly jumps to the `patch` subcommand.
  88See ``Interactive mode'' for details.
  89
  90-e, \--edit::
  91        Open the diff vs. the index in an editor and let the user
  92        edit it.  After the editor was closed, adjust the hunk headers
  93        and apply the patch to the index.
  94+
  95The intent of this option is to pick and choose lines of the patch to
  96apply, or even to modify the contents of lines to be staged. This can be
  97quicker and more flexible than using the interactive hunk selector.
  98However, it is easy to confuse oneself and create a patch that does not
  99apply to the index. See EDITING PATCHES below.
 100
 101-u::
 102--update::
 103        Only match <filepattern> against already tracked files in
 104        the index rather than the working tree. That means that it
 105        will never stage new files, but that it will stage modified
 106        new contents of tracked files and that it will remove files
 107        from the index if the corresponding files in the working tree
 108        have been removed.
 109+
 110If no <filepattern> is given, default to "."; in other words,
 111update all tracked files in the current directory and its
 112subdirectories.
 113
 114-A::
 115--all::
 116        Like `-u`, but match <filepattern> against files in the
 117        working tree in addition to the index. That means that it
 118        will find new files as well as staging modified content and
 119        removing files that are no longer in the working tree.
 120
 121-N::
 122--intent-to-add::
 123        Record only the fact that the path will be added later. An entry
 124        for the path is placed in the index with no content. This is
 125        useful for, among other things, showing the unstaged content of
 126        such files with `git diff` and committing them with `git commit
 127        -a`.
 128
 129--refresh::
 130        Don't add the file(s), but only refresh their stat()
 131        information in the index.
 132
 133--ignore-errors::
 134        If some files could not be added because of errors indexing
 135        them, do not abort the operation, but continue adding the
 136        others. The command shall still exit with non-zero status.
 137        The configuration variable `add.ignoreErrors` can be set to
 138        true to make this the default behaviour.
 139
 140--ignore-missing::
 141        This option can only be used together with --dry-run. By using
 142        this option the user can check if any of the given files would
 143        be ignored, no matter if they are already present in the work
 144        tree or not.
 145
 146\--::
 147        This option can be used to separate command-line options from
 148        the list of files, (useful when filenames might be mistaken
 149        for command-line options).
 150
 151
 152Configuration
 153-------------
 154
 155The optional configuration variable `core.excludesfile` indicates a path to a
 156file containing patterns of file names to exclude from git-add, similar to
 157$GIT_DIR/info/exclude.  Patterns in the exclude file are used in addition to
 158those in info/exclude.  See linkgit:gitrepository-layout[5].
 159
 160
 161EXAMPLES
 162--------
 163
 164* Adds content from all `*.txt` files under `Documentation` directory
 165and its subdirectories:
 166+
 167------------
 168$ git add Documentation/\*.txt
 169------------
 170+
 171Note that the asterisk `*` is quoted from the shell in this
 172example; this lets the command include the files from
 173subdirectories of `Documentation/` directory.
 174
 175* Considers adding content from all git-*.sh scripts:
 176+
 177------------
 178$ git add git-*.sh
 179------------
 180+
 181Because this example lets the shell expand the asterisk (i.e. you are
 182listing the files explicitly), it does not consider
 183`subdir/git-foo.sh`.
 184
 185Interactive mode
 186----------------
 187When the command enters the interactive mode, it shows the
 188output of the 'status' subcommand, and then goes into its
 189interactive command loop.
 190
 191The command loop shows the list of subcommands available, and
 192gives a prompt "What now> ".  In general, when the prompt ends
 193with a single '>', you can pick only one of the choices given
 194and type return, like this:
 195
 196------------
 197    *** Commands ***
 198      1: status       2: update       3: revert       4: add untracked
 199      5: patch        6: diff         7: quit         8: help
 200    What now> 1
 201------------
 202
 203You also could say `s` or `sta` or `status` above as long as the
 204choice is unique.
 205
 206The main command loop has 6 subcommands (plus help and quit).
 207
 208status::
 209
 210   This shows the change between HEAD and index (i.e. what will be
 211   committed if you say `git commit`), and between index and
 212   working tree files (i.e. what you could stage further before
 213   `git commit` using `git add`) for each path.  A sample output
 214   looks like this:
 215+
 216------------
 217              staged     unstaged path
 218     1:       binary      nothing foo.png
 219     2:     +403/-35        +1/-1 git-add--interactive.perl
 220------------
 221+
 222It shows that foo.png has differences from HEAD (but that is
 223binary so line count cannot be shown) and there is no
 224difference between indexed copy and the working tree
 225version (if the working tree version were also different,
 226'binary' would have been shown in place of 'nothing').  The
 227other file, git-add{litdd}interactive.perl, has 403 lines added
 228and 35 lines deleted if you commit what is in the index, but
 229working tree file has further modifications (one addition and
 230one deletion).
 231
 232update::
 233
 234   This shows the status information and issues an "Update>>"
 235   prompt.  When the prompt ends with double '>>', you can
 236   make more than one selection, concatenated with whitespace or
 237   comma.  Also you can say ranges.  E.g. "2-5 7,9" to choose
 238   2,3,4,5,7,9 from the list.  If the second number in a range is
 239   omitted, all remaining patches are taken.  E.g. "7-" to choose
 240   7,8,9 from the list.  You can say '*' to choose everything.
 241+
 242What you chose are then highlighted with '*',
 243like this:
 244+
 245------------
 246           staged     unstaged path
 247  1:       binary      nothing foo.png
 248* 2:     +403/-35        +1/-1 git-add--interactive.perl
 249------------
 250+
 251To remove selection, prefix the input with `-`
 252like this:
 253+
 254------------
 255Update>> -2
 256------------
 257+
 258After making the selection, answer with an empty line to stage the
 259contents of working tree files for selected paths in the index.
 260
 261revert::
 262
 263  This has a very similar UI to 'update', and the staged
 264  information for selected paths are reverted to that of the
 265  HEAD version.  Reverting new paths makes them untracked.
 266
 267add untracked::
 268
 269  This has a very similar UI to 'update' and
 270  'revert', and lets you add untracked paths to the index.
 271
 272patch::
 273
 274  This lets you choose one path out of a 'status' like selection.
 275  After choosing the path, it presents the diff between the index
 276  and the working tree file and asks you if you want to stage
 277  the change of each hunk.  You can say:
 278
 279       y - stage this hunk
 280       n - do not stage this hunk
 281       q - quit; do not stage this hunk nor any of the remaining ones
 282       a - stage this hunk and all later hunks in the file
 283       d - do not stage this hunk nor any of the later hunks in the file
 284       g - select a hunk to go to
 285       / - search for a hunk matching the given regex
 286       j - leave this hunk undecided, see next undecided hunk
 287       J - leave this hunk undecided, see next hunk
 288       k - leave this hunk undecided, see previous undecided hunk
 289       K - leave this hunk undecided, see previous hunk
 290       s - split the current hunk into smaller hunks
 291       e - manually edit the current hunk
 292       ? - print help
 293+
 294After deciding the fate for all hunks, if there is any hunk
 295that was chosen, the index is updated with the selected hunks.
 296
 297diff::
 298
 299  This lets you review what will be committed (i.e. between
 300  HEAD and index).
 301
 302
 303EDITING PATCHES
 304---------------
 305
 306Invoking `git add -e` or selecting `e` from the interactive hunk
 307selector will open a patch in your editor; after the editor exits, the
 308result is applied to the index. You are free to make arbitrary changes
 309to the patch, but note that some changes may have confusing results, or
 310even result in a patch that cannot be applied.  If you want to abort the
 311operation entirely (i.e., stage nothing new in the index), simply delete
 312all lines of the patch. The list below describes some common things you
 313may see in a patch, and which editing operations make sense on them.
 314
 315--
 316added content::
 317
 318Added content is represented by lines beginning with "{plus}". You can
 319prevent staging any addition lines by deleting them.
 320
 321removed content::
 322
 323Removed content is represented by lines beginning with "-". You can
 324prevent staging their removal by converting the "-" to a " " (space).
 325
 326modified content::
 327
 328Modified content is represented by "-" lines (removing the old content)
 329followed by "{plus}" lines (adding the replacement content). You can
 330prevent staging the modification by converting "-" lines to " ", and
 331removing "{plus}" lines. Beware that modifying only half of the pair is
 332likely to introduce confusing changes to the index.
 333--
 334
 335There are also more complex operations that can be performed. But beware
 336that because the patch is applied only to the index and not the working
 337tree, the working tree will appear to "undo" the change in the index.
 338For example, introducing a new line into the index that is in neither
 339the HEAD nor the working tree will stage the new line for commit, but
 340the line will appear to be reverted in the working tree.
 341
 342Avoid using these constructs, or do so with extreme caution.
 343
 344--
 345removing untouched content::
 346
 347Content which does not differ between the index and working tree may be
 348shown on context lines, beginning with a " " (space).  You can stage
 349context lines for removal by converting the space to a "-". The
 350resulting working tree file will appear to re-add the content.
 351
 352modifying existing content::
 353
 354One can also modify context lines by staging them for removal (by
 355converting " " to "-") and adding a "{plus}" line with the new content.
 356Similarly, one can modify "{plus}" lines for existing additions or
 357modifications. In all cases, the new modification will appear reverted
 358in the working tree.
 359
 360new content::
 361
 362You may also add new content that does not exist in the patch; simply
 363add new lines, each starting with "{plus}". The addition will appear
 364reverted in the working tree.
 365--
 366
 367There are also several operations which should be avoided entirely, as
 368they will make the patch impossible to apply:
 369
 370* adding context (" ") or removal ("-") lines
 371* deleting context or removal lines
 372* modifying the contents of context or removal lines
