1git-prune(1) 2============ 3 4NAME 5---- 6git-prune - Prune all unreachable objects from the object database 7 8 9SYNOPSIS 10-------- 11'git-prune' [-n] [--expire <expire>] [--] [<head>...] 12 13DESCRIPTION 14----------- 15 16NOTE: In most cases, users should run linkgit:git-gc[1], which calls 17git-prune. See the section "NOTES", below. 18 19This runs `git-fsck --unreachable` using all the refs 20available in `$GIT_DIR/refs`, optionally with additional set of 21objects specified on the command line, and prunes all unpacked 22objects unreachable from any of these head objects from the object database. 23In addition, it 24prunes the unpacked objects that are also found in packs by 25running `git prune-packed`. 26 27Note that unreachable, packed objects will remain. If this is 28not desired, see linkgit:git-repack[1]. 29 30OPTIONS 31------- 32 33-n:: 34 Do not remove anything; just report what it would 35 remove. 36 37\--:: 38 Do not interpret any more arguments as options. 39 40--expire <time>:: 41 Only expire loose objects older than <time>. 42 43<head>...:: 44 In addition to objects 45 reachable from any of our references, keep objects 46 reachable from listed <head>s. 47 48EXAMPLE 49------- 50 51To prune objects not used by your repository nor another that 52borrows from your repository via its 53`.git/objects/info/alternates`: 54 55------------ 56$ git prune $(cd ../another && $(git-rev-parse --all)) 57------------ 58 59Notes 60----- 61 62In most cases, users will not need to call git-prune directly, but 63should instead call linkgit:git-gc[1], which handles pruning along with 64many other housekeeping tasks. 65 66For a description of which objects are considered for pruning, see 67git-fsck's --unreachable option. 68 69SEE ALSO 70-------- 71 72linkgit:git-fsck[1], 73linkgit:git-gc[1], 74linkgit:git-reflog[1] 75 76Author 77------ 78Written by Linus Torvalds <torvalds@osdl.org> 79 80Documentation 81-------------- 82Documentation by David Greaves, Junio C Hamano and the git-list <git@vger.kernel.org>. 83 84GIT 85--- 86Part of the linkgit:git[1] suite
