GIT-INDEX-PACK(1)                Git Manual                GIT-INDEX-PACK(1)

NAME         top

       git-index-pack - Build pack index file for an existing packed archive

SYNOPSIS         top

       git index-pack [-v] [-o <index-file>] <pack-file>
       git index-pack --stdin [--fix-thin] [--keep] [-v] [-o <index-file>]
                        [<pack-file>]

DESCRIPTION         top

       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         top

       -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.

       --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         top

       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\t", or "keep\t" 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.
