  23OPTIONS
  24-------
  25--object-dir::
  26        Use given directory for the location of packfiles and commit graph
  27        file. This parameter exists to specify the location of an alternate
  28        that only has the objects directory, not a full .git directory. The
  29        commit graph file is expected to be at <dir>/info/commit-graph and
  30        the packfiles are expected to be in <dir>/pack.

  33COMMANDS
  34--------
  35'write'::
  36
  37Write a commit graph file based on the commits found in packfiles.
  38+
  39With the `--stdin-packs` option, generate the new commit graph by
  40walking objects only in the specified pack-indexes. (Cannot be combined
  41with `--stdin-commits` or `--reachable`.)
  42+
  43With the `--stdin-commits` option, generate the new commit graph by
  44walking commits starting at the commits specified in stdin as a list
  45of OIDs in hex, one OID per line. (Cannot be combined with
  46`--stdin-packs` or `--reachable`.)
  47+
  48With the `--reachable` option, generate the new commit graph by walking
  49commits starting at all refs. (Cannot be combined with `--stdin-commits`
  50or `--stdin-packs`.)
  51+
  52With the `--append` option, include all commits that are present in the
  53existing commit-graph file.
  54
  55'read'::
  56
  57Read a graph file given by the commit-graph file and output basic
  58details about the graph file. Used for debugging purposes.
  59
  60'verify'::
  61
  62Read the commit-graph file and verify its contents against the object
  63database. Used to check for corrupted data.
  64
  65
  66EXAMPLES
  67--------
  68
  69* Write a commit graph file for the packed commits in your local .git folder.
  70+
  71------------------------------------------------
  72$ git commit-graph write
  73------------------------------------------------
  74
  75* Write a graph file, extending the current graph file using commits
  76* in <pack-index>.
  77+
  78------------------------------------------------
  79$ echo <pack-index> | git commit-graph write --stdin-packs
  80------------------------------------------------
  81
  82* Write a graph file containing all reachable commits.
  83+
  84------------------------------------------------
  85$ git show-ref -s | git commit-graph write --stdin-commits
  86------------------------------------------------
  87
  88* Write a graph file containing all commits in the current
  89* commit-graph file along with those reachable from HEAD.
  90+
  91------------------------------------------------
  92$ git rev-parse HEAD | git commit-graph write --stdin-commits --append
  93------------------------------------------------
  94
  95* Read basic information from the commit-graph file.
  96+
