We check + `<dir>/packs/multi-pack-index` for the current MIDX file, and + `<dir>/packs` for the pack-files to index. + +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 +----------------------------------------------- + + +SEE ALSO +-------- +See link:technical/multi-pack-index.html[The Multi-Pack-Index Design +Document] and link:technical/pack-format.html[The Multi-Pack-Index +Format] for more information on the multi-pack-index feature. + + +GIT +--- +Part of the linkgit:git[1] suite |
