1git-gc(1) 2========= 3 4NAME 5---- 6git-gc - Cleanup unnecessary files and optimize the local repository 7 8 9SYNOPSIS 10-------- 11'git-gc' 12 13DESCRIPTION 14----------- 15Runs a number of housekeeping tasks within the current repository, 16such as compressing file revisions (to reduce disk space and increase 17performance) and removing unreachable objects which may have been 18created from prior invocations of gitlink:git-add[1]. 19 20Users are encouraged to run this task on a regular basis within 21each repository to maintain good disk space utilization and good 22operating performance. 23 24Configuration 25------------- 26 27The optional configuration variable 'gc.reflogExpire' can be 28set to indicate how long historical entries within each branch's 29reflog should remain available in this repository. The setting is 30expressed as a length of time, for example '90 days' or '3 months'. 31It defaults to '90 days'. 32 33The optional configuration variable 'gc.reflogExpireUnreachable' 34can be set to indicate how long historical reflog entries which 35are not part of the current branch should remain available in 36this repository. These types of entries are generally created as 37a result of using `git commit \--amend` or `git rebase` and are the 38commits prior to the amend or rebase occurring. Since these changes 39are not part of the current project most users will want to expire 40them sooner. This option defaults to '30 days'. 41 42The optional configuration variable 'gc.rerereresolved' indicates 43how long records of conflicted merge you resolved earlier are 44kept. This defaults to 60 days. 45 46The optional configuration variable 'gc.rerereunresolved' indicates 47how long records of conflicted merge you have not resolved are 48kept. This defaults to 15 days. 49 50 51See Also 52-------- 53gitlink:git-prune[1] 54gitlink:git-reflog[1] 55gitlink:git-repack[1] 56gitlink:git-rerere[1] 57 58Author 59------ 60Written by Shawn O.
