git-commit-graph \- Write and verify Git commit\-graph files
.SH "SYNOPSIS"

\fIgit commit\-graph read\fR [\-\-object\-dir <dir>]

.SH "DESCRIPTION"
.sp
Manage the serialized commit\-graph file\&.
.SH "OPTIONS"
.PP
\-\-object\-dir
.RS 4
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
\fB\&.git\fR
directory\&. The commit\-graph file is expected to be at
\fB<dir>/info/commit\-graph\fR
and the packfiles are expected to be in
\fB<dir>/pack\fR\&.
.RE
.SH "COMMANDS"
.PP
\fIwrite\fR
.RS 4
Write a commit\-graph file based on the commits found in packfiles\&.
.sp
With the
\fB\-\-stdin\-packs\fR
option, generate the new commit graph by walking objects only in the specified pack\-indexes\&. (Cannot be combined with
\fB\-\-stdin\-commits\fR
or
\fB\-\-reachable\fR\&.)
.sp
With the
\fB\-\-stdin\-commits\fR
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
\fB\-\-stdin\-packs\fR
or
\fB\-\-reachable\fR\&.)
.sp
With the
\fB\-\-reachable\fR
option, generate the new commit graph by walking commits starting at all refs\&. (Cannot be combined with
\fB\-\-stdin\-commits\fR
or
\fB\-\-stdin\-packs\fR\&.)
.sp
With the
\fB\-\-append\fR
option, include all commits that are present in the existing commit\-graph file\&.
.RE
.PP
\fIread\fR
.RS 4
Read the commit\-graph file and output basic details about it\&. Used for debugging purposes\&.
.RE
.PP
\fIverify\fR
.RS 4
Read the commit\-graph file and verify its contents against the object database\&. Used to check for corrupted data\&.
