  10 --------
  11 [verse]
  12 'git multi-pack-index' [--object-dir=<dir>] [--[no-]progress] <subcommand>
  13
  14 DESCRIPTION
  15 -----------
  16 Write or verify a multi-pack-index (MIDX) file.
  17
  18 OPTIONS
  19 -------
  20
  21 --object-dir=<dir>::
  22         Use given directory for the location of Git objects. We check
  23         `<dir>/packs/multi-pack-index` for the current MIDX file, and
  24         `<dir>/packs` for the pack-files to index.
  25
  26 --[no-]progress::
  27         Turn progress on/off explicitly. If neither is specified, progress is
  28         shown if standard error is connected to a terminal.
  29
  30 The following subcommands are available:
  31
  32 write::
  33         Write a new MIDX file.
  34
  35 verify::
  36         Verify the contents of the MIDX file.
  37
  38 expire::
  39         Delete the pack-files that are tracked  by the MIDX file, but
  40         have no objects referenced by the MIDX. Rewrite the MIDX file
  41         afterward to remove all references to these pack-files.
  42
  43 repack::
  44         Create a new pack-file containing objects in small pack-files
  45         referenced by the multi-pack-index. If the size given by the
  46         `--batch-size=<size>` argument is zero, then create a pack
  47         containing all objects referenced by the multi-pack-index. For
  48         a non-zero batch size, Select the pack-files by examining packs
  49         from oldest-to-newest, computing the "expected size" by counting
  50         the number of objects in the pack referenced by the
  51         multi-pack-index, then divide by the total number of objects in
  52         the pack and multiply by the pack size. We select packs with
  53         expected size below the batch size until the set of packs have
  54         total expected size at least the batch size, or all pack-files
  55         are considered. If only one pack-file is selected, then do
  56         nothing. If a new pack-file is created, rewrite the
  57         multi-pack-index to reference the new pack-file. A later run of
  58         'git multi-pack-index expire' will delete the pack-files that
  59         were part of this batch.
  60 +
  61 If `repack.packKeptObjects` is `false`, then any pack-files with an
  62 associated `.keep` file will not be selected for the batch to repack.
