NAME

       git-commit-graph - Write and verify Git commit-graph files

SYNOPSIS

       git commit-graph read [--object-dir <dir>]
       git commit-graph verify [--object-dir <dir>]
       git commit-graph write <options> [--object-dir <dir>]

DESCRIPTION

       Manage the serialized commit-graph file.

OPTIONS

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

COMMANDS

       write
           Write a commit-graph file based on the commits found in packfiles.

           With the --stdin-packs option, generate the new commit graph by walking objects only
           in the specified pack-indexes. (Cannot be combined with --stdin-commits or
           --reachable.)

           With the --stdin-commits option, generate the new commit graph by walking commits
           starting at the commits specified in stdin as a list of OIDs in hex, one OID per line.
           (Cannot be combined with --stdin-packs or --reachable.)

           With the --reachable option, generate the new commit graph by walking commits starting
           at all refs. (Cannot be combined with --stdin-commits or --stdin-packs.)

           With the --append option, include all commits that are present in the existing
           commit-graph file.

       read
           Read the commit-graph file and output basic details about it. Used for debugging
           purposes.

       verify
           Read the commit-graph file and verify its contents against the object database. Used
           to check for corrupted data.

EXAMPLES

       ·   Write a commit-graph file for the packed commits in your local .git directory.

               $ git commit-graph write

       ·   Write a commit-graph file, extending the current commit-graph file using commits in
           <pack-index>.

               $ echo <pack-index> | git commit-graph write --stdin-packs

       ·   Write a commit-graph file containing all reachable commits.

               $ git show-ref -s | git commit-graph write --stdin-commits

       ·   Write a commit-graph file containing all commits in the current commit-graph file
           along with those reachable from HEAD.

               $ git rev-parse HEAD | git commit-graph write --stdin-commits --append

       ·   Read basic information from the commit-graph file.

               $ git commit-graph read
