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] [--progress] [--expire <time>] [--] [<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--progress:: 46 Show progress. 47 48--expire <time>:: 49 Only expire loose objects older than <time>. 50 51\--:: 52 Do not interpret any more arguments as options. 53 54<head>...:: 55 In addition to objects 56 reachable from any of our references, keep objects 57 reachable from listed <head>s. 58 59EXAMPLE 60------- 61 62To prune objects not used by your repository or another that 63borrows from your repository via its 64`.git/objects/info/alternates`: 65 66------------ 67$ git prune $(cd ../another && git rev-parse --all) 68------------ 69 70Notes 71----- 72 73In most cases, users will not need to call 'git prune' directly, but 74should instead call 'git gc', which handles pruning along with 75many other housekeeping tasks. 76 77For a description of which objects are considered for pruning, see 78'git fsck''s --unreachable option. 79 80SEE ALSO 81-------- 82 83linkgit:git-fsck[1], 84linkgit:git-gc[1], 85linkgit:git-reflog[1] 86 87GIT 88--- 89Part of the linkgit:git[1] suite
