NAME

       git-multi-pack-index - Write and verify multi-pack-indexes

SYNOPSIS

       git multi-pack-index [--object-dir=<dir>] [--[no-]progress] <subcommand>

DESCRIPTION

       Write or verify a multi-pack-index (MIDX) file.

OPTIONS

       --object-dir=<dir>
           Use given directory for the location of Git objects. We check <dir>/packs/multi-pack-index for the
           current MIDX file, and <dir>/packs for the pack-files to index.

       --[no-]progress
           Turn progress on/off explicitly. If neither is specified, progress is shown if standard error is
           connected to a terminal.

       The following subcommands are available:

       write
           Write a new MIDX file.

       verify
           Verify the contents of the MIDX file.

       expire
           Delete the pack-files that are tracked by the MIDX file, but have no objects referenced by the MIDX.
           Rewrite the MIDX file afterward to remove all references to these pack-files.

       repack
           Create a new pack-file containing objects in small pack-files referenced by the multi-pack-index. If
           the size given by the --batch-size=<size> argument is zero, then create a pack containing all objects
           referenced by the multi-pack-index. For a non-zero batch size, Select the pack-files by examining
           packs from oldest-to-newest, computing the "expected size" by counting the number of objects in the
           pack referenced by the multi-pack-index, then divide by the total number of objects in the pack and
           multiply by the pack size. We select packs with expected size below the batch size until the set of
           packs have total expected size at least the batch size. If the total size does not reach the batch
           size, then do nothing. If a new pack- file is created, rewrite the multi-pack-index to reference the
           new pack-file. A later run of git multi-pack-index expire will delete the pack-files that were part
           of this batch.

EXAMPLES

       •   Write a MIDX file for the packfiles in the current .git folder.

               $ git multi-pack-index write

       •   Write a MIDX file for the packfiles in an alternate object store.

               $ git multi-pack-index --object-dir <alt> write

       •   Verify the MIDX file for the packfiles in the current .git folder.

               $ git multi-pack-index verify
