  18-----------
  19
  20Manage the serialized commit-graph file.

  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`.
  31

  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 the commit-graph file and output basic details about it.
  58Used 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`
  70  directory.
  71+
  72------------------------------------------------
  73$ git commit-graph write
  74------------------------------------------------
  75
  76* Write a commit-graph file, extending the current commit-graph file
  77  using commits in `<pack-index>`.
  78+
  79------------------------------------------------
  80$ echo <pack-index> | git commit-graph write --stdin-packs
  81------------------------------------------------
  82
  83* Write a commit-graph file containing all reachable commits.
  84+
  85------------------------------------------------
  86$ git show-ref -s | git commit-graph write --stdin-commits
  87------------------------------------------------
  88
  89* Write a commit-graph file containing all commits in the current
  90  commit-graph file along with those reachable from `HEAD`.
  91+
  92------------------------------------------------
  93$ git rev-parse HEAD | git commit-graph write --stdin-commits --append
  94------------------------------------------------
  95
  96* Read basic information from the commit-graph file.
  97+
  98------------------------------------------------
  99$ git commit-graph read
