       git-repack - Pack unpacked objects in a repository

       git repack [-a] [-A] [-d] [-f] [-F] [-l] [-n] [-q] [--window=<n>] [--depth=<n>]

       This script is used to combine all objects that do not currently reside in a "pack", into a pack. It can also
       be used to re-organize existing packs into a single, more efficient pack.

       A pack is a collection of objects, individually compressed, with delta compression applied, stored in a single
       file, with an associated index file.

       Packs are used to reduce the load on mirror systems, backup engines, disk storage, etc.

           Instead of incrementally packing the unpacked objects, pack everything referenced into a single pack.
           Especially useful when packing a repository that is used for private development. Use with -d. This will
           clean up the objects that git prune leaves behind, but git fsck --full --dangling shows as dangling.

           Note that users fetching over dumb protocols will have to fetch the whole new pack in order to get any
           contained object, no matter how many other objects in that pack they already have locally.

           Same as -a, unless -d is used. Then any unreachable objects in a previous pack become loose, unpacked
           objects, instead of being left in the old pack. Unreachable objects are never intentionally added to a
           pack, even when repacking. This option prevents unreachable objects from being immediately deleted by way
           of being left in the old pack and then removed. Instead, the loose unreachable objects will be pruned
           according to normal expiry rules with the next git gc invocation. See git-gc(1).

           After packing, if the newly created packs make some existing packs redundant, remove the redundant packs.
           Also run git prune-packed to remove redundant loose object files.

           Pass the --local option to git pack-objects. See git-pack-objects(1).

           Pass the --no-reuse-delta option to git-pack-objects, see git-pack-objects(1).

           Pass the --no-reuse-object option to git-pack-objects, see git-pack-objects(1).

           Pass the -q option to git pack-objects. See git-pack-objects(1).

           Do not update the server information with git update-server-info. This option skips updating local catalog
           files needed to publish this repository (or a direct copy of it) over HTTP or FTP. See git-update-server-

       --window=<n>, --depth=<n>
           These two options affect how the objects contained in the pack are stored using delta compression. The
           objects are first internally sorted by type, size and optionally names and compared against the other
           objects within --window to see if using delta compression saves space.  --depth limits the maximum delta
           depth; making it too deep affects the performance on the unpacker side, because delta data needs to be
           applied that many times to get to the necessary object. The default value for --window is 10 and --depth is

           This option provides an additional limit on top of --window; the window size will dynamically scale down so
           as to not take up more than <n> bytes in memory. This is useful in repositories with a mix of large and
           small objects to not run out of memory with a large window, but still be able to take advantage of the
           large window for the smaller objects. The size can be suffixed with "k", "m", or "g".  --window-memory=0
           makes memory usage unlimited, which is the default.

           Maximum size of each output pack file. The size can be suffixed with "k", "m", or "g". The minimum size
           allowed is limited to 1 MiB. If specified, multiple packfiles may be created. The default is unlimited,
           unless the config variable pack.packSizeLimit is set.

       By default, the command passes --delta-base-offset option to git pack-objects; this typically results in
       slightly smaller packs, but the generated packs are incompatible with versions of Git older than version 1.4.4.
       If you need to share your repository with such ancient Git versions, either directly or via the dumb http or
       rsync protocol, then you need to set the configuration variable repack.UseDeltaBaseOffset to "false" and
       repack. Access from old Git versions over the native protocol is unaffected by this option as the conversion is
       performed on the fly as needed in that case.
