Thus +after making any changes to the working tree, and before running +the commit command, you must use the `add` command to add any new or +modified files to the index. + +This command can be performed multiple times before a commit. It only +adds the content of the specified file(s) at the time the add command is +run; if you want subsequent changes included in the next commit, then +you must run `git add` again to add the new content to the index. + +The `git status` command can be used to obtain a summary of which +files have changes that are staged for the next commit. + +The `git add` command will not add ignored files by default. If any +ignored files were explicitly specified on the command line, `git add` +will fail with a list of ignored files. Ignored files reached by +directory recursion or filename globbing performed by Git (quote your +globs before the shell) will be silently ignored. The 'git add' command can +be used to add ignored files with the `-f` (force) option. + +Please see linkgit:git-commit[1] for alternative ways to add content to a +commit. + + +OPTIONS +------- +...:: + Files to add content from. Fileglobs (e.g. `*.c`) can + be given to add all matching files. Also a + leading directory name (e.g. `dir` to add `dir/file1` + and `dir/file2`) can be given to update the index to + match the current state of the directory as a whole (e.g. + specifying `dir` will record not just a file `dir/file1` + modified in the working tree, a file `dir/file2` added to + the working tree, but also a file `dir/file3` removed from + the working tree). Note that older versions of Git used + to ignore removed files; use `--no-all` option if you want + to add modified or new files but ignore removed ones. ++ +For more details about the syntax, see the 'pathspec' entry +in linkgit:gitglossary[7]. + +-n:: +--dry-run:: + Don't actually add the file(s), just show if they exist and/or will + be ignored. + +-v:: +--verbose:: + Be verbose. + +-f:: +--force:: + Allow adding otherwise ignored files. + +--sparse:: + Allow updating index entries outside of the sparse-checkout cone. + Normally, `git add` refuses to update index entries whose paths do + not fit within the sparse-checkout cone, since those files might + be removed from the working tree without warning. See + linkgit:git-sparse-checkout[1] for more details. + +-i:: +--interactive:: + Add modified contents in the working tree interactively to + the index. Optional path arguments may be supplied to limit + operation to a subset of the working tree. See ``Interactive + mode'' for details. + +-p:: +--patch:: + Interactively choose hunks of patch between the index and the + work tree and add them to the index. This gives the user a chance + to review the difference before adding modified contents to the + index. ++ +This effectively runs `add --interactive`, but bypasses the +initial command menu and directly jumps to the `patch` subcommand. +See ``Interactive mode'' for details. + +-e:: +--edit:: + Open the diff vs. the index in an editor and let the user + edit it. After the editor was closed, adjust the hunk headers + and apply the patch to the index. ++ +The intent of this option is to pick and choose lines of the patch to +apply, or even to modify the contents of lines to be staged. This can be +quicker and more flexible than using the interactive hunk selector. +However, it is easy to confuse oneself and create a patch that does not +apply to the index. See EDITING PATCHES below. + +-u:: +--update:: + Update the index just where it already has an entry matching + . This removes as well as modifies index entries to + match the working tree, but adds no new files. ++ +If no is given when `-u` option is used, all +tracked files in the entire working tree are updated (old versions +of Git used to limit the update to the current directory and its +subdirectories). + +-A:: +--all:: +--no-ignore-removal:: + Update the index not only where the working tree has a file + matching but also where the index already has an + entry. This adds, modifies, and removes index entries to + match the working tree. ++ +If no is given when `-A` option is used, all +files in the entire working tree are updated (old versions +of Git used to limit the update to the current directory and its +subdirectories). + +--no-all:: +--ignore-removal:: + Update the index by adding new files that are unknown to the + index and files modified in the working tree, but ignore + files that have been removed from the working tree. This + option is a no-op when no is used. ++ +This option is primarily to help users who are used to older +versions of Git, whose "git add ..." was a synonym +for "git add --no-all ...", i.e. ignored removed files. + +-N:: +--intent-to-add:: + Record only the fact that the path will be added later. An entry + for the path is placed in the index with no content. This is + useful for, among other things, showing the unstaged content of + such files with `git diff` and committing them with `git commit + -a`. + +--refresh:: + Don't add the file(s), but only refresh their stat() + information in the index. + +--ignore-errors:: + If some files could not be added because of errors indexing + them, do not abort the operation, but continue adding the + others. The command shall still exit with non-zero status. + The configuration variable `add.ignoreErrors` can be set to + true to make this the default behaviour. + +--ignore-missing:: + This option can only be used together with --dry-run. By using + this option the user can check if any of the given files would + be ignored, no matter if they are already present in the work + tree or not. + +--no-warn-embedded-repo:: + By default, `git add` will warn when adding an embedded + repository to the index without using `git submodule add` to + create an entry in `.gitmodules`. This option will suppress the + warning (e.g., if you are manually performing operations on + submodules). + +--renormalize:: + Apply the "clean" process freshly to all tracked files to + forcibly add them again to the index. This is useful after + changing `core.autocrlf` configuration or the `text` attribute + in order to correct files added with wrong CRLF/LF line endings. + This option implies `-u`. Lone CR characters are untouched, thus + while a CRLF cleans to LF, a CRCRLF sequence is only partially + cleaned to CRLF. + +--chmod=(+|-)x:: + Override the executable bit of the added files. The executable + bit is only changed in the index, the files on disk are left + unchanged. + +--pathspec-from-file=:: + Pathspec is passed in `` instead of commandline args. If + `` is exactly `-` then standard input is used. Pathspec + elements are separated by LF or CR/LF. Pathspec elements can be + quoted as explained for the configuration variable `core.quotePath` + (see linkgit:git-config[1]). See also `--pathspec-file-nul` and + global `--literal-pathspecs`. + +--pathspec-file-nul:: + Only meaningful with `--pathspec-from-file`. Pathspec elements are + separated with NUL character and all other characters are taken + literally (including newlines and quotes). + +\--:: + This option can be used to separate command-line options from + the list of files, (useful when filenames might be mistaken + for command-line options). + + +EXAMPLES +-------- + +* Adds content from all `*.txt` files under `Documentation` directory + and its subdirectories: ++ +------------ +$ git add Documentation/\*.txt +------------ ++ +Note that the asterisk `*` is quoted from the shell in this +example; this lets the command include the files from +subdirectories of `Documentation/` directory. + +* Considers adding content from all git-*.sh scripts: ++ +------------ +$ git add git-*.sh +------------ ++ +Because this example lets the shell expand the asterisk (i.e. you are +listing the files explicitly), it does not consider +`subdir/git-foo.sh`. + +INTERACTIVE MODE +---------------- +When the command enters the interactive mode, it shows the +output of the 'status' subcommand, and then goes into its +interactive command loop. + +The command loop shows the list of subcommands available, and +gives a prompt "What now> ". In general, when the prompt ends +with a single '>', you can pick only one of the choices given +and type return, like this: + +------------ + *** Commands *** + 1: status 2: update 3: revert 4: add untracked + 5: patch 6: diff 7: quit 8: help + What now> 1 +------------ + +You also could say `s` or `sta` or `status` above as long as the +choice is unique. + +The main command loop has 6 subcommands (plus help and quit). + +status:: + + This shows the change between HEAD and index (i.e. what will be + committed if you say `git commit`), and between index and + working tree files (i.e. what you could stage further before + `git commit` using `git add`) for each path. A sample output + looks like this: ++ +------------ + staged unstaged path + 1: binary nothing foo.png + 2: +403/-35 +1/-1 git-add--interactive.perl +------------ ++ +It shows that foo.png has differences from HEAD (but that is +binary so line count cannot be shown) and there is no +difference between indexed copy and the working tree +version (if the working tree version were also different, +'binary' would have been shown in place of 'nothing'). The +other file, git-add{litdd}interactive.perl, has 403 lines added +and 35 lines deleted if you commit what is in the index, but +working tree file has further modifications (one addition and +one deletion). + +update:: + + This shows the status information and issues an "Update>>" + prompt. When the prompt ends with double '>>', you can + make more than one selection, concatenated with whitespace or + comma. Also you can say ranges. E.g. "2-5 7,9" to choose + 2,3,4,5,7,9 from the list. If the second number in a range is + omitted, all remaining patches are taken. E.g. "7-" to choose + 7,8,9 from the list. You can say '*' to choose everything. ++ +What you chose are then highlighted with '*', +like this: ++ +------------ + staged unstaged path + 1: binary nothing foo.png +* 2: +403/-35 +1/-1 git-add--interactive.perl +------------ ++ +To remove selection, prefix the input with `-` +like this: ++ +------------ +Update>> -2 +------------ ++ +After making the selection, answer with an empty line to stage the +contents of working tree files for selected paths in the index. + +revert:: + + This has a very similar UI to 'update', and the staged + information for selected paths are reverted to that of the + HEAD version. Reverting new paths makes them untracked. + +add untracked:: + + This has a very similar UI to 'update' and + 'revert', and lets you add untracked paths to the index. + +patch:: + + This lets you choose one path out of a 'status' like selection. + After choosing the path, it presents the diff between the index + and the working tree file and asks you if you want to stage + the change of each hunk. You can select one of the following + options and type return: + + y - stage this hunk + n - do not stage this hunk + q - quit; do not stage this hunk or any of the remaining ones + a - stage this hunk and all later hunks in the file + d - do not stage this hunk or any of the later hunks in the file + g - select a hunk to go to + / - search for a hunk matching the given regex + j - leave this hunk undecided, see next undecided hunk + J - leave this hunk undecided, see next hunk + k - leave this hunk undecided, see previous undecided hunk + K - leave this hunk undecided, see previous hunk + s - split the current hunk into smaller hunks + e - manually edit the current hunk + ? - print help ++ +After deciding the fate for all hunks, if there is any hunk +that was chosen, the index is updated with the selected hunks. ++ +You can omit having to type return here, by setting the configuration +variable `interactive.singleKey` to `true`. + +diff:: + + This lets you review what will be committed (i.e. between + HEAD and index). + + +EDITING PATCHES +--------------- + +Invoking `git add -e` or selecting `e` from the interactive hunk +selector will open a patch in your editor; after the editor exits, the +result is applied to the index. You are free to make arbitrary changes +to the patch, but note that some changes may have confusing results, or +even result in a patch that cannot be applied. If you want to abort the +operation entirely (i.e., stage nothing new in the index), simply delete +all lines of the patch. The list below describes some common things you +may see in a patch, and which editing operations make sense on them. + +-- +added content:: + +Added content is represented by lines beginning with "{plus}". You can +prevent staging any addition lines by deleting them. + +removed content:: + +Removed content is represented by lines beginning with "-". You can +prevent staging their removal by converting the "-" to a " " (space). + +modified content:: + +Modified content is represented by "-" lines (removing the old content) +followed by "{plus}" lines (adding the replacement content). You can +prevent staging the modification by converting "-" lines to " ", and +removing "{plus}" lines. Beware that modifying only half of the pair is +likely to introduce confusing changes to the index. +-- + +There are also more complex operations that can be performed. But beware +that because the patch is applied only to the index and not the working +tree, the working tree will appear to "undo" the change in the index. +For example, introducing a new line into the index that is in neither +the HEAD nor the working tree will stage the new line for commit, but +the line will appear to be reverted in the working tree. + +Avoid using these constructs, or do so with extreme caution. + +-- +removing untouched content:: + +Content which does not differ between the index and working tree may be +shown on context lines, beginning with a " " (space). You can stage +context lines for removal by converting the space to a "-". The +resulting working tree file will appear to re-add the content. + +modifying existing content:: + +One can also modify context lines by staging them for removal (by +converting " " to "-") and adding a "{plus}" line with the new content. +Similarly, one can modify "{plus}" lines for existing additions or +modifications. In all cases, the new modification will appear reverted +in the working tree. + +new content:: + +You may also add new content that does not exist in the patch; simply +add new lines, each starting with "{plus}". The addition will appear +reverted in the working tree. +-- + +There are also several operations which should be avoided entirely, as +they will make the patch impossible to apply: + +* adding context (" ") or removal ("-") lines +* deleting context or removal lines +* modifying the contents of context or removal lines + +CONFIGURATION +------------- + +include::includes/cmd-config-section-all.txt[] + +include::config/add.txt[] + +SEE ALSO +-------- +linkgit:git-status[1] +linkgit:git-rm[1] +linkgit:git-reset[1] +linkgit:git-mv[1] +linkgit:git-commit[1] +linkgit:git-update-index[1] + +GIT +--- +Part of the linkgit:git[1] suite -- cgit v1.2.3
