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.

       --check-self-contained-and-connected
	   Die if the pack contains broken links. For internal use only.

       --fsck-objects
	   Die if the pack contains broken objects. For internal use only.

       --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 threads.

       --max-input-size=<size>
	   Die, if the pack is larger than <size>.

NOTE

       Once the index has been created, the list of object names is sorted and the SHA-1 hash of that list is printed to stdout. If --stdin was
       also used then this is prefixed by either "pack	", or "keep	" if a new .keep file was successfully created. This is useful to remove a
       .keep file used as a lock to prevent the race with git repack mentioned above.
