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

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

       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

           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

           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 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.

           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.

           Like --keep create a .keep file before moving the index into its
           final destination, but rather than creating an empty file place why
           followed by an LF into the .keep file. The why message can later be
           searched for within all .keep files to locate any which have
           outlived their usefulness.

           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.

           Die, if the pack contains broken objects or links.

       Once the index has been created, the list of object names is sorted and
       the SHA1 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
