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'. 27It also removes entries from .git/shallow that are not reachable by 28any ref. 29 30Note that unreachable, packed objects will remain. If this is 31not desired, see linkgit:git-repack[1]. 32 33OPTIONS 34------- 35 36-n:: 37--dry-run:: 38 Do not remove anything; just report what it would 39 remove. 40 41-v:: 42--verbose:: 43 Report all removed objects. 44 45\--:: 46 Do not interpret any more arguments as options. 47 48--expire <time>:: 49 Only expire loose objects older than <time>. 50 51<head>...:: 52 In addition to objects 53 reachable from any of our references, keep objects 54 reachable from listed <head>s. 55 56EXAMPLE 57------- 58 59To prune objects not used by your repository or another that 60borrows from your repository via its 61`.git/objects/info/alternates`: 62 63------------ 64$ git prune $(cd ../another && git rev-parse --all) 65------------ 66 67Notes 68----- 69 70In most cases, users will not need to call 'git prune' directly, but 71should instead call 'git gc', which handles pruning along with 72many other housekeeping tasks. 73 74For a description of which objects are considered for pruning, see 75'git fsck''s --unreachable option. 76 77SEE ALSO 78-------- 79 80linkgit:git-fsck[1], 81linkgit:git-gc[1], 82linkgit:git-reflog[1] 83 84GIT 85--- 86Part of the linkgit:git[1] suite
