GIT-INDEX-PACK(1) Git Manual GIT-INDEX-PACK(1)
NAME
git-index-pack - Build pack index file for an existing packed archive
SYNOPSIS
git index-pack [-v] [-o <index-file>] <pack-file>
git index-pack --stdin [--fix-thin] [--keep] [-v] [-o <index-file>]
[<pack-file>]
DESCRIPTION
Reads a packed archive (.pack) from the specified file, and builds a pack index file (.idx) for it. The packed
archive together with the pack index can then be placed in the objects/pack/ directory of a Git repository.
OPTIONS
-v
Be verbose about what is going on, including progress status.
-o <index-file>
Write the generated pack index into the specified file. Without this option the name of pack index file is
constructed from the name of packed archive file by replacing .pack with .idx (and the program fails if
the name of packed archive does not end with .pack).
--stdin
When this flag is provided, the pack is read from stdin instead and a copy is then written to <pack-file>.
If <pack-file> is not specified, the pack is written to objects/pack/ directory of the current Git
repository with a default name determined from the pack content. If <pack-file> is not specified consider
using --keep to prevent a race condition between this process and git repack.
--fix-thin
Fix a "thin" pack produced by git pack-objects --thin (see git-pack-objects(1) for details) by adding the
excluded objects the deltified objects are based on to the pack. This option only makes sense in
conjunction with --stdin.
--keep
Before moving the index into its final destination create an empty .keep file for the associated pack
file. This option is usually necessary with --stdin to prevent a simultaneous git repack process from
deleting the newly constructed pack and index before refs can be updated to use objects contained in the
pack.
--keep=<msg>
Like --keep create a .keep file before moving the index into its final destination, but rather than
creating an empty file place <msg> followed by an LF into the .keep file. The <msg> message can later be
searched for within all .keep files to locate any which have outlived their usefulness.
--index-version=<version>[,<offset>]
This is intended to be used by the test suite only. It allows to force the version for the generated pack
index, and to force 64-bit index entries on objects located above the given offset.
--strict
Die, if the pack contains broken objects or links.
--threads=<n>
Specifies the number of threads to spawn when resolving deltas. This requires that index-pack be compiled
with pthreads otherwise this option is ignored with a warning. This is meant to reduce packing time on
multiprocessor machines. The required amount of memory for the delta search window is however multiplied
by the number of threads. Specifying 0 will cause Git to auto-detect the number of CPU’s and use maximum 3
