git-log(1) ========== NAME ---- git-log - Show commit logs SYNOPSIS -------- [synopsis] git log [] [] [[--] ...] DESCRIPTION ----------- Shows the commit logs. :git-log: 1 include::rev-list-description.adoc[] The command takes options applicable to the linkgit:git-rev-list[1] command to control what is shown and how, and options applicable to the linkgit:git-diff[1] command to control how the changes each commit introduces are shown. OPTIONS ------- `--follow`:: Continue listing the history of a file beyond renames (works only for a single file). `--no-decorate`:: `--decorate[=(short|full|auto|no)]`:: Print out the ref names of any commits that are shown. Possible values are: + ---- `short`;; the ref name prefixes `refs/heads/`, `refs/tags/` and `refs/remotes/` are not printed. `full`;; the full ref name (including prefix) is printed. `auto`:: 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 option `--decorate` is short-hand for `--decorate=short`. Default to configuration value of `log.decorate` if configured, otherwise, `auto`. `--decorate-refs=`:: `--decorate-refs-exclude=`:: For each candidate reference, do not use it for decoration if it matches any of the __ parameters given to `--decorate-refs-exclude` or if it doesn't match any of the __ parameters given to `--decorate-refs`. The `log.excludeDecoration` config option allows excluding refs from the decorations, but an explicit `--decorate-refs` pattern will override a match in `log.excludeDecoration`. + If none of these options or config settings are given, then references are used as decoration if they match `HEAD`, `refs/heads/`, `refs/remotes/`, `refs/stash/`, or `refs/tags/`. `--clear-decorations`:: When specified, this option clears all previous `--decorate-refs` or `--decorate-refs-exclude` options and relaxes the default decoration filter to include all references. This option is assumed if the config value `log.initialDecorationSet` is set to `all`. `--source`:: Print out the ref name given on the command line by which each commit was reached. `--mailmap`:: `--no-mailmap`:: `--use-mailmap`:: `--no-use-mailmap`:: Use mailmap file to map author and committer names and email addresses to canonical real names and email addresses. See linkgit:git-shortlog[1]. `--full-diff`:: Without this flag, `git log -p ...` 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 "`...`" limits only commits, and doesn't limit diff for those commits. + Note that this affects all diff-based output types, e.g. those produced by `--stat`, etc. `--log-size`:: Include a line `log size ` in the output for each commit, where __ 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. include::line-range-options.adoc[] __:: Show only commits in the specified revision range. When no __ 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 __, see the 'Specifying Ranges' section of linkgit: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. + Paths may need to be prefixed with `--` to separate them from options or the revision range, when confusion arises. include::rev-list-options.adoc[] include::pretty-formats.adoc[] DIFF FORMATTING --------------- By default, `git log` does not generate any diff output. The options below can be used to show the changes made by each commit. Note that unless one of `--diff-merges` variants (including short `-m`, `-c`, `--cc`, and `--dd` options) is explicitly given, merge commits will not show a diff, even if a diff format like `--patch` is selected, nor will they match search options like `-S`. The exception is when `--first-parent` is in use, in which case `first-parent` is the default format for merge commits. :git-log: 1 :diff-merges-default: `off` include::diff-options.adoc[] include::diff-generate-patch.adoc[] EXAMPLES -------- `git log --no-merges`:: Show the whole commit history, but skip any merges `git log v2.6.12.. include/scsi drivers/scsi`:: Show all commits since version 'v2.6.12' that changed any file in the `include/scsi` or `drivers/scsi` subdirectories `git log --since="2 weeks ago" -- gitk`:: Show the changes during the last two weeks to the file `gitk`. The `--` is necessary to avoid confusion with the *branch* named `gitk` `git log --name-status release..test`:: 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. `git log --follow builtin/rev-list.c`:: Shows the commits that changed `builtin/rev-list.c`, including those commits that occurred before the file was given its present name. `git log --branches --not --remotes=origin`:: 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). `git log master --not --remotes=*/master`:: Shows all commits that are in local master but not in any remote repository master branches. `git log -p -m --first-parent`:: 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. `git log -L '/int main/',/^}/:main.c`:: Shows how the function `main()` in the file `main.c` evolved over time. `git log -3`:: Limits the number of commits to show to 3. DISCUSSION ---------- include::i18n.adoc[] CONFIGURATION ------------- See linkgit:git-config[1] for core variables and linkgit:git-diff[1] for settings related to diff generation. `format.pretty`:: Default for the `--format` option. (See 'Pretty Formats' above.) Defaults to `medium`. `i18n.logOutputEncoding`:: Encoding to use when displaying logs. (See 'Discussion' above.) Defaults to the value of `i18n.commitEncoding` if set, and UTF-8 otherwise. include::includes/cmd-config-section-rest.adoc[] include::config/log.adoc[] include::config/notes.adoc[] GIT --- Part of the linkgit:git[1] suite
