Continue listing the history of a file beyond renames (works only for a single file).

Print out the ref names of any commits that are shown. If short is specified, the ref name prefixes refs/heads/, refs/tags/ and refs/remotes/ will not be printed. If full is specified, the full ref name (including prefix) will be printed. If auto is specified, then if the output is going to a terminal, the ref names are shown as if short were given, otherwise no ref names are shown. The default option is short.

Print out the ref name given on the command line by which each commit was reached.

Use mailmap file to map author and committer names and email addresses to canonical real names and email addresses. See git-shortlog[1].

Without this flag, git log -p <path>... shows commits that touch the specified paths, and diffs about the same specified paths. With this, the full diff is shown for commits that touch the specified paths; this means that "<path>…​" limits only commits, and doesn’t limit diff for those commits.

Include a line “log size <number>” in the output for each commit, where <number> is the length of that commit’s message in bytes. Intended to speed up tools that read log messages from git log output by allowing them to allocate space in advance.

Trace the evolution of the line range given by "<start>,<end>" (or the function name regex <funcname>) within the <file>. You may not give any pathspec limiters. This is currently limited to a walk starting from a single revision, i.e., you may only give zero or one positive revision arguments. You can specify this option more than once.

Show only commits in the specified revision range. When no <revision range> is specified, it defaults to HEAD (i.e. the whole history leading to the current commit). origin..HEAD specifies all the commits reachable from the current commit (i.e. HEAD), but not from origin. For a complete list of ways to spell <revision range>, see the Specifying Ranges section of gitrevisions[7].

Show only commits that are enough to explain how the files that match the specified paths came to be. See History Simplification below for details and other simplification modes.

Generate patch (see section on generating patches).

Suppress diff output. Useful for commands like git show that show the patch by default, or to cancel the effect of --patch.

Generate diffs with <n> lines of context instead of the usual three. Implies -p.

For each commit, show a summary of changes using the raw diff format. See the "RAW OUTPUT FORMAT" section of git-diff[1]. This is different from showing the log itself in raw format, which you can achieve with --format=raw.

Synonym for -p --raw.

These are to help debugging and tuning an experimental heuristic (which is off by default) that shifts the hunk boundary in an attempt to make the resulting patch easier to read.

Spend extra time to make sure the smallest possible diff is produced.

Generate a diff using the "patience diff" algorithm.

Generate a diff using the "histogram diff" algorithm.

Choose a diff algorithm. The variants are as follows:

Generate a diffstat. By default, as much space as necessary will be used for the filename part, and the rest for the graph part. Maximum width defaults to terminal width, or 80 columns if not connected to a terminal, and can be overridden by <width>. The width of the filename part can be limited by giving another width <name-width> after a comma. The width of the graph part can be limited by using --stat-graph-width=<width> (affects all commands generating a stat graph) or by setting diff.statGraphWidth=<width> (does not affect git format-patch). By giving a third parameter <count>, you can limit the output to the first <count> lines, followed by ... if there are more.

Similar to --stat, but shows number of added and deleted lines in decimal notation and pathname without abbreviation, to make it more machine friendly. For binary files, outputs two - instead of saying 0 0.

Output only the last line of the --stat format containing total number of modified files, as well as number of added and deleted lines.

Output the distribution of relative amount of changes for each sub-directory. The behavior of --dirstat can be customized by passing it a comma separated list of parameters. The defaults are controlled by the diff.dirstat configuration variable (see git-config[1]). The following parameters are available:

Output a condensed summary of extended header information such as creations, renames and mode changes.

Synonym for -p --stat.

Separate the commits with NULs instead of with new newlines.

Show only names of changed files.

Show only names and status of changed files. See the description of the --diff-filter option on what the status letters mean.

Specify how differences in submodules are shown. When --submodule or --submodule=log is given, the log format is used. This format lists the commits in the range like git-submodule[1] summary does. Omitting the --submodule option or specifying --submodule=short, uses the short format. This format just shows the names of the commits at the beginning and end of the range. Can be tweaked via the diff.submodule configuration variable.

Show colored diff. --color (i.e. without =<when>) is the same as --color=always. <when> can be one of always, never, or auto.

Turn off colored diff. It is the same as --color=never.

Show a word diff, using the <mode> to delimit changed words. By default, words are delimited by whitespace; see --word-diff-regex below. The <mode> defaults to plain, and must be one of:

Use <regex> to decide what a word is, instead of considering runs of non-whitespace to be a word. Also implies --word-diff unless it was already enabled.

Equivalent to --word-diff=color plus (if a regex was specified) --word-diff-regex=<regex>.

Turn off rename detection, even when the configuration file gives the default to do so.

Warn if changes introduce conflict markers or whitespace errors. What are considered whitespace errors is controlled by core.whitespace configuration. By default, trailing whitespaces (including lines that solely consist of whitespaces) and a space character that is immediately followed by a tab character inside the initial indent of the line are considered whitespace errors. Exits with non-zero status if problems are found. Not compatible with --exit-code.

Highlight whitespace errors on lines specified by <kind> in the color specified by color.diff.whitespace. <kind> is a comma separated list of old, new, context. When this option is not given, only whitespace errors in new lines are highlighted. E.g. --ws-error-highlight=new,old highlights whitespace errors on both deleted and added lines. all can be used as a short-hand for old,new,context.

Instead of the first handful of characters, show the full pre- and post-image blob object names on the "index" line when generating patch format output.

In addition to --full-index, output a binary diff that can be applied with git-apply.

Instead of showing the full 40-byte hexadecimal object name in diff-raw format output and diff-tree header lines, show only a partial prefix. This is independent of the --full-index option above, which controls the diff-patch output format. Non default number of digits can be specified with --abbrev=<n>.

Break complete rewrite changes into pairs of delete and create. This serves two purposes:

If generating diffs, detect and report renames for each commit. For following files across renames while traversing history, see --follow. If n is specified, it is a threshold on the similarity index (i.e. amount of addition/deletions compared to the file’s size). For example, -M90% means Git should consider a delete/add pair to be a rename if more than 90% of the file hasn’t changed. Without a % sign, the number is to be read as a fraction, with a decimal point before it. I.e., -M5 becomes 0.5, and is thus the same as -M50%. Similarly, -M05 is the same as -M5%. To limit detection to exact renames, use -M100%. The default similarity index is 50%.

Detect copies as well as renames. See also --find-copies-harder. If n is specified, it has the same meaning as for -M<n>.

For performance reasons, by default, -C option finds copies only if the original file of the copy was modified in the same changeset. This flag makes the command inspect unmodified files as candidates for the source of copy. This is a very expensive operation for large projects, so use it with caution. Giving more than one -C option has the same effect.

Omit the preimage for deletes, i.e. print only the header but not the diff between the preimage and /dev/null. The resulting patch is not meant to be applied with patch or git apply; this is solely for people who want to just concentrate on reviewing the text after the change. In addition, the output obviously lack enough information to apply such a patch in reverse, even manually, hence the name of the option.

The -M and -C options require O(n^2) processing time where n is the number of potential rename/copy targets. This option prevents rename/copy detection from running if the number of rename/copy targets exceeds the specified number.

Select only files that are Added (A), Copied (C), Deleted (D), Modified (M), Renamed (R), have their type (i.e. regular file, symlink, submodule, …​) changed (T), are Unmerged (U), are Unknown (X), or have had their pairing Broken (B). Any combination of the filter characters (including none) can be used. When * (All-or-none) is added to the combination, all paths are selected if there is any file that matches other criteria in the comparison; if there is no file that matches other criteria, nothing is selected.

Look for differences that change the number of occurrences of the specified string (i.e. addition/deletion) in a file. Intended for the scripter’s use.

Look for differences whose patch text contains added/removed lines that match <regex>.

+    return !regexec(regexp, two->ptr, 1, &regmatch, 0);
...
-    hit = !regexec(regexp, mf2.ptr, 1, &regmatch, 0);

When -S or -G finds a change, show all the changes in that changeset, not just the files that contain the change in <string>.

Treat the <string> given to -S as an extended POSIX regular expression to match.

Output the patch in the order specified in the <orderfile>, which has one shell glob pattern per line. This overrides the diff.orderFile configuration variable (see git-config[1]). To cancel diff.orderFile, use -O/dev/null.

Swap two inputs; that is, show differences from index or on-disk file to tree contents.

When run from a subdirectory of the project, it can be told to exclude changes outside the directory and show pathnames relative to it with this option. When you are not in a subdirectory (e.g. in a bare repository), you can name which subdirectory to make the output relative to by giving a <path> as an argument.

Treat all files as text.

Ignore changes in whitespace at EOL.

Ignore changes in amount of whitespace. This ignores whitespace at line end, and considers all other sequences of one or more whitespace characters to be equivalent.

Ignore whitespace when comparing lines. This ignores differences even if one line has whitespace where the other line has none.

Ignore changes whose lines are all blank.

Show the context between diff hunks, up to the specified number of lines, thereby fusing hunks that are close to each other.

Show whole surrounding functions of changes.

Allow an external diff helper to be executed. If you set an external diff driver with gitattributes[5], you need to use this option with git-log[1] and friends.

Disallow external diff drivers.

Allow (or disallow) external text conversion filters to be run when comparing binary files. See gitattributes[5] for details. Because textconv filters are typically a one-way conversion, the resulting diff is suitable for human consumption, but cannot be applied. For this reason, textconv filters are enabled by default only for git-diff[1] and git-log[1], but not for git-format-patch[1] or diff plumbing commands.

Ignore changes to submodules in the diff generation. <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 git-config[1] or 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 until 1.7.0). Using "all" hides all changes to submodules.

Show the given source prefix instead of "a/".

Show the given destination prefix instead of "b/".

Do not show any source or destination prefix.

Show the whole commit history, but skip any merges

Show all commits since version v2.6.12 that changed any file in the include/scsi or drivers/scsi subdirectories

Show the changes during the last two weeks to the file gitk. The “--” is necessary to avoid confusion with the branch named gitk

Show the commits that are in the "test" branch but not yet in the "release" branch, along with the list of paths each commit modifies.

Shows the commits that changed builtin/rev-list.c, including those commits that occurred before the file was given its present name.

Shows all commits that are in any of local branches but not in any of remote-tracking branches for origin (what you have that origin doesn’t).

Shows all commits that are in local master but not in any remote repository master branches.

Shows the history including change diffs, but only from the “main branch” perspective, skipping commits that come from merged branches, and showing full diffs of changes introduced by the merges. This makes sense only when following a strict policy of merging all topic branches when staying on a single integration branch.

Shows how the function main() in the file main.c evolved over time.

Limits the number of commits to show to 3.

Default for the --format option. (See Pretty Formats above.) Defaults to medium.

Encoding to use when displaying logs. (See Discussion above.) Defaults to the value of i18n.commitEncoding if set, and UTF-8 otherwise.

Default format for human-readable dates. (Compare the --date option.) Defaults to "default", which means to write dates like Sat May 8 19:35:34 2010 -0500.

If true, git log will act as if the --follow option was used when a single <path> is given. This has the same limitations as --follow, i.e. it cannot be used to follow multiple files and does not work well on non-linear history.

If false, git log and related commands will not treat the initial commit as a big creation event. Any root commits in git log -p output would be shown without a diff attached. The default is true.

If true, git log and related commands will act as if the --show-signature option was passed to them.

See git-shortlog[1].

Which refs, in addition to the default set by core.notesRef or GIT_NOTES_REF, to read notes from when showing commit messages with the log family of commands. See git-notes[1].
