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] [-v] [--expire <expire>] [--] [<head>...] 12 13DESCRIPTION 14----------- 15 16NOTE: In most cases, users should run 'git gc', which calls 17'git prune'. See the section "NOTES", below. 18 19This runs 'git fsck --unreachable' using all the refs 20available in `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-v:: 38 Report all removed objects. 39 40\--:: 41 Do not interpret any more arguments as options. 42 43--expire <time>:: 44 Only expire loose objects older than <time>. 45 46<head>...:: 47 In addition to objects 48 reachable from any of our references, keep objects 49 reachable from listed <head>s. 50 51EXAMPLE 52------- 53 54To prune objects not used by your repository nor another that 55borrows from your repository via its 56`.git/objects/info/alternates`: 57 58------------ 59$ git prune $(cd ../another && $(git rev-parse --all)) 60------------ 61 62Notes 63----- 64 65In most cases, users will not need to call 'git prune' directly, but 66should instead call 'git gc', which handles pruning along with 67many other housekeeping tasks. 68 69For a description of which objects are considered for pruning, see 70'git fsck''s --unreachable option. 71 72SEE ALSO 73-------- 74 75linkgit:git-fsck[1], 76linkgit:git-gc[1], 77linkgit:git-reflog[1] 78 79Author 80------ 81Written by Linus Torvalds <torvalds@osdl.org> 82 83Documentation 84-------------- 85Documentation by David Greaves, Junio C Hamano and the git-list <git@vger.kernel.org>. 86 87GIT 88--- 89Part of the linkgit:git[1] suite
