GIT-INDEX-PACK(1)                                            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.


NOTE
       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
       above.
