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