Git Log Command

git-log(1) ========== NAME ---- git-log - Show commit logs SYNOPSIS -------- [verse] 'git log' [<options>] [<revision-range>] [[--] <path>...] 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. 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 option `--decorate` is short-hand for `--decorate=short`. Default to configuration value of `log.decorate` if configured, otherwise, `auto`. --decorate-refs=<pattern>:: --decorate-refs-exclude=<pattern>:: For each candidate reference, do not use it for decoration if it matches any patterns given to `--decorate-refs-exclude` or if it doesn't match any of the patterns 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. --[no-]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 <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. + Note that this affects all diff-based output types, e.g. those produced by `--stat`, etc. --log-size:: 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. include::line-range-options.adoc[] <revision-range>:: 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`.

The git-log command is used to show commit logs, allowing users to view the history of commits in a repository, with various options to control the output and display of commit information, including options to decorate commits, show commit history beyond renames, and display differences introduced by each commit, providing a detailed overview of the repository's history and development.
