The first +are what you _would_ commit by running `git commit`; the second and +third are what you _could_ commit by running 'git add' before running +`git commit`. + +OPTIONS +------- + +-s:: +--short:: + Give the output in the short-format. + +-b:: +--branch:: + Show the branch and tracking info even in short-format. + +--show-stash:: + Show the number of entries currently stashed away. + +--porcelain[=<version>]:: + Give the output in an easy-to-parse format for scripts. + This is similar to the short output, but will remain stable + across Git versions and regardless of user configuration. See + below for details. ++ +The version parameter is used to specify the format version. +This is optional and defaults to the original version 'v1' format. + +--long:: + Give the output in the long-format. This is the default. + +-v:: +--verbose:: + In addition to the names of files that have been changed, also + show the textual changes that are staged to be committed + (i.e., like the output of `git diff --cached`). If `-v` is specified + twice, then also show the changes in the working tree that + have not yet been staged (i.e., like the output of `git diff`). + +-u[<mode>]:: +--untracked-files[=<mode>]:: + Show untracked files. ++ +The mode parameter is used to specify the handling of untracked files. +It is optional: it defaults to 'all', and if specified, it must be +stuck to the option (e.g. `-uno`, but not `-u no`). ++ +The possible options are: ++ + - 'no' - Show no untracked files. + - 'normal' - Shows untracked files and directories. + - 'all' - Also shows individual files in untracked directories. ++ +When `-u` option is not used, untracked files and directories are +shown (i.e. the same as specifying `normal`), to help you avoid +forgetting to add newly created files. Because it takes extra work +to find untracked files in the filesystem, this mode may take some +time in a large working tree. +Consider enabling untracked cache and split index if supported (see +`git update-index --untracked-cache` and `git update-index +--split-index`), Otherwise you can use `no` to have `git status` +return more quickly without showing untracked files. ++ +The default can be changed using the status.showUntrackedFiles +configuration variable documented in linkgit:git-config[1]. + +--ignore-submodules[=<when>]:: + Ignore changes to submodules when looking for changes. <when> can be + either "none", "untracked", "dirty" or "all", which is the default. + Using "none" will consider the submodule modified when it either contains + untracked or modified files or its HEAD differs from the commit recorded + in the superproject and can be used to override any settings of the + 'ignore' option in linkgit:git-config[1] or linkgit:gitmodules[5]. When + "untracked" is used submodules are not considered dirty when they only + contain untracked content (but they are still scanned for modified + content). Using "dirty" ignores all changes to the work tree of submodules, + only changes to the commits stored in the superproject are shown (this was + the behavior before 1.7.0). Using "all" hides all changes to submodules + (and suppresses the output of submodule summaries when the config option + `status.submoduleSummary` is set). + +--ignored[=<mode>]:: + Show ignored files as well. ++ +The mode parameter is used to specify the handling of ignored files. +It is optional: it defaults to 'traditional'. ++ +The possible options are: ++ + - 'traditional' - Shows ignored files and directories, unless + --untracked-files=all is specified, in which case + individual files in ignored directories are + displayed. + - 'no' - Show no ignored files. + - 'matching' - Shows ignored files and directories matching an + ignore pattern. ++ +When 'matching' mode is specified, paths that explicitly match an +ignored pattern are shown. If a directory matches an ignore pattern, +then it is shown, but not paths contained in the ignored directory. If +a directory does not match an ignore pattern, but all contents are +ignored, then the directory is not shown, but all contents are shown. + +-z:: + Terminate entries with NUL, instead of LF. This implies + the `--porcelain=v1` output format if no other format is given. + +--column[=<options>]:: +--no-column:: + Display untracked files in columns. See configuration variable + column.status for option syntax.`--column` and `--no-column` + without options are equivalent to 'always' and 'never' + respectively. + +--ahead-behind:: +--no-ahead-behind:: + Display or do not display detailed ahead/behind counts for the + branch relative to its upstream branch. Defaults to true. + +--renames:: +--no-renames:: + Turn on/off rename detection regardless of user configuration. + See also linkgit:git-diff[1] `--no-renames`. + +--find-renames[=<n>]:: + Turn on rename detection, optionally setting the similarity + threshold. + See also linkgit:git-diff[1] `--find-renames`. + +<pathspec>...:: + See the 'pathspec' entry in linkgit:gitglossary[7]. + +OUTPUT +------ +The output from this command is designed to be used as a commit +template comment. +The default, long format, is designed to be human readable, +verbose and descriptive. Its contents and format are subject to change +at any time. + +The paths mentioned in the output, unlike many other Git commands, are +made relative to the current directory if you are working in a +subdirectory (this is on purpose, to help cutting and pasting). See +the status.relativePaths config option below. + +Short Format +~~~~~~~~~~~~ + +In the short-format, the status of each path is shown as one of these +forms + + XY PATH + XY ORIG_PATH -> PATH + +where `ORIG_PATH` is where the renamed/copied contents came +from. `ORIG_PATH` is only shown when the entry is renamed or +copied. The `XY` is a two-letter status code. + +The fields (including the `->`) are separated from each other by a +single space. If a filename contains whitespace or other nonprintable +characters, that field will be quoted in the manner of a C string +literal: surrounded by ASCII double quote (34) characters, and with +interior special characters backslash-escaped. + +For paths with merge conflicts, `X` and `Y` show the modification +states of each side of the merge. For paths that do not have merge +conflicts, `X` shows the status of the index, and `Y` shows the status +of the work tree. For untracked paths, `XY` are `??`. Other status +codes can be interpreted as follows: + +* ' ' = unmodified +* 'M' = modified +* 'A' = added +* 'D' = deleted +* 'R' = renamed +* 'C' = copied +* 'U' = updated but unmerged + +Ignored files are not listed, unless `--ignored` option is in effect, +in which case `XY` are `!!`. + +.... +X Y Meaning +------------------------------------------------- + [AMD] not updated +M [ MD] updated in index +A [ MD] added to index +D deleted from index +R [ MD] renamed in index +C [ MD] copied in index +[MARC] index and work tree matches +[ MARC] M work tree changed since index +[ MARC] D deleted in work tree +[ D] R renamed in work tree +[ D] C copied in work tree +------------------------------------------------- +D D unmerged, both deleted +A U unmerged, added by us +U D unmerged, deleted by them +U A unmerged, added by them +D U unmerged, deleted by us +A A unmerged, both added +U U unmerged, both modified +------------------------------------------------- +? ? untracked +! ! ignored +------------------------------------------------- +.... + +Submodules have more state and instead report + M the submodule has a different HEAD than + recorded in the index + m the submodule has modified content + ? the submodule has untracked files +since modified content or untracked files in a submodule cannot be added +via `git add` in the superproject to prepare a commit. + +'m' and '?' are applied recursively. For example if a nested submodule +in a submodule contains an untracked file, this is reported as '?' as well. + +If -b is used the short-format status is preceded by a line + + ## branchname tracking info + +Porcelain Format Version 1 +~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Version 1 porcelain format is similar to the short format, but is guaranteed +not to change in a backwards-incompatible way between Git versions or +based on user configuration. This makes it ideal for parsing by scripts. +The description of the short format above also describes the porcelain +format, with a few exceptions: + +1. The user's color.status configuration is not respected; color will + always be off. + +2. The user's status.relativePaths configuration is not respected; paths + shown will always be relative to the repository root. + +There is also an alternate -z format recommended for machine parsing. In +that format, the status field is the same, but some other things +change. First, the '\->' is omitted from rename entries and the field +order is reversed (e.g 'from \-> to' becomes 'to from'). Second, a NUL +(ASCII 0) follows each filename, replacing space as a field separator +and the terminating newline (but a space still separates the status +field from the first filename). Third, filenames containing special +characters are not specially formatted; no quoting or +backslash-escaping is performed. + +Any submodule changes are reported as modified `M` instead of `m` or single `?`. + +Porcelain Format Version 2 +~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Version 2 format adds more detailed information about the state of +the worktree and changed items. Version 2 also defines an extensible +set of easy to parse optional headers. + +Header lines start with "#" and are added in response to specific +command line arguments. Parsers should ignore headers they +don't recognize. + +Branch Headers +^^^^^^^^^^^^^^ + +If `--branch` is given, a series of header lines are printed with +information about the current branch. + +.... +Line Notes +------------------------------------------------------------ +# branch.oid <commit> | (initial) Current commit. +# branch.head <branch> | (detached) Current branch. +# branch.upstream <upstream_branch> If upstream is set. +# branch.ab +<ahead> -<behind> If upstream is set and + the commit is present. +------------------------------------------------------------ +.... + +Changed Tracked Entries +^^^^^^^^^^^^^^^^^^^^^^^ + +Following the headers, a series of lines are printed for tracked +entries. One of three different line formats may be used to describe +an entry depending on the type of change. Tracked entries are printed +in an undefined order; parsers should allow for a mixture of the 3 +line types in any order. + +Ordinary changed entries have the following format: + + 1 <XY> <sub> <mH> <mI> <mW> <hH> <hI> <path> + +Renamed or copied entries have the following format: + + 2 <XY> <sub> <mH> <mI> <mW> <hH> <hI> <X><score> <path><sep><origPath> + +.... +Field Meaning +-------------------------------------------------------- +<XY> A 2 character field containing the staged and + unstaged XY values described in the short format, + with unchanged indicated by a "." rather than + a space. +<sub> A 4 character field describing the submodule state. + "N..." when the entry is not a submodule. + "S<c><m><u>" when the entry is a submodule. + <c> is "C" if the commit changed; otherwise ".". + <m> is "M" if it has tracked changes; otherwise ".". + <u> is "U" if there are untracked changes; otherwise ".". +<mH> The octal file mode in HEAD. +<mI> The octal file mode in the index. +<mW> The octal file mode in the worktree. +<hH> The object name in HEAD. +<hI> The object name in the index. +<X><score> The rename or copy score (denoting the percentage + of similarity between the source and target of the + move or copy). For example "R100" or "C75". +<path> The pathname. In a renamed/copied entry, this + is the target path. +<sep> When the `-z` option is used, the 2 pathnames are separated + with a NUL (ASCII 0x00) byte; otherwise, a tab (ASCII 0x09) + byte separates them. +<origPath> The pathname in the commit at HEAD or in the index. + This is only present in a renamed/copied entry, and + tells where the renamed/copied contents came from. +-------------------------------------------------------- +.... + +Unmerged entries have the following format; the first character is +a "u" to distinguish from ordinary changed entries. + + u <xy> <sub> <m1> <m2> <m3> <mW> <h1> <h2> <h3> <path> + +.... +Field Meaning +-------------------------------------------------------- +<XY> A 2 character field describing the conflict type + as described in the short format. +<sub> A 4 character field describing the submodule state + as described above. +<m1> The octal file mode in stage 1. +<m2> The octal file mode in stage 2. +<m3> The octal file mode in stage 3. +<mW> The octal file mode in the worktree. +<h1> The object name in stage 1. +<h2> The object name in stage 2. +<h3> The object name in stage 3. +<path> The pathname. +-------------------------------------------------------- +.... + +Other Items +^^^^^^^^^^^ + +Following the tracked entries (and if requested), a series of +lines will be printed for untracked and then ignored items +found in the worktree. + +Untracked items have the following format: + + ? <path> + +Ignored items have the following format: + + ! <path> + +Pathname Format Notes and -z +^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +When the `-z` option is given, pathnames are printed as is and +without any quoting and lines are terminated with a NUL (ASCII 0x00) +byte. + +Without the `-z` option, pathnames with "unusual" characters are +quoted as explained for the configuration variable `core.quotePath` +(see linkgit:git-config[1]). + + +CONFIGURATION +------------- + +The command honors `color.status` (or `status.color` -- they +mean the same thing and the latter is kept for backward +compatibility) and `color.status.<slot>` configuration variables +to colorize its output. + +If the config variable `status.relativePaths` is set to false, then all +paths shown are relative to the repository root, not to the current +directory. + +If `status.submoduleSummary` is set to a non zero number or true (identical +to -1 or an unlimited number), the submodule summary will be enabled for +the long format and a summary of commits for modified submodules will be +shown (see --summary-limit option of linkgit:git-submodule[1]). Please note +that the summary output from the status command will be suppressed for all +submodules when `diff.ignoreSubmodules` is set to 'all' or only for those +submodules where `submodule.<name>.ignore=all`. To also view the summary for +ignored submodules you can either use the --ignore-submodules=dirty command +line option or the 'git submodule summary' command, which shows a similar +output but does not honor these settings. + +BACKGROUND REFRESH +------------------ + +By default, `git status` will automatically refresh the index, updating +the cached stat information from the working tree and writing out the +result. Writing out the updated index is an optimization that isn't +strictly necessary (`status` computes the values for itself, but writing +them out is just to save subsequent programs from repeating our +computation). When `status` is run in the background, the lock held +during the write may conflict with other simultaneous processes, causing +them to fail. Scripts running `status` in the background should consider +using `git --no-optional-locks status` (see linkgit:git[1] for details). + +SEE ALSO +-------- +linkgit:gitignore[5] + +GIT +--- +Part of the linkgit:git[1] suite |
