 | NAME | 
 | ---- | 
 | git-multi-pack-index - Write and verify multi-pack-indexes | 
 |  | 
 |  | 
 | SYNOPSIS | 
 | -------- | 
 | [verse] | 
 | '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, or all pack-files | 
 | 	are considered. If only one pack-file is selected, 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. | 
 | + | 
 | If `repack.packKeptObjects` is `false`, then any pack-files with an | 
 | associated `.keep` file will not be selected for the batch to repack. | 
 |  | 
 |  | 
 | 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 |
