SYNOPSIS
--------
-'git-gc' [--prune] [--aggressive]
+'git-gc' [--aggressive] [--auto] [--quiet]
DESCRIPTION
-----------
Runs a number of housekeeping tasks within the current repository,
such as compressing file revisions (to reduce disk space and increase
performance) and removing unreachable objects which may have been
-created from prior invocations of gitlink:git-add[1].
+created from prior invocations of linkgit:git-add[1].
Users are encouraged to run this task on a regular basis within
each repository to maintain good disk space utilization and good
-operating performance.
+operating performance. Some git commands may automatically run
+`git-gc`; see the `--auto` flag below for details.
OPTIONS
-------
---prune::
- Usually `git-gc` packs refs, expires old reflog entries,
- packs loose objects,
- and removes old 'rerere' records. Removal
- of unreferenced loose objects is an unsafe operation
- while other git operations are in progress, so it is not
- done by default. Pass this option if you want it, and only
- when you know nobody else is creating new objects in the
- repository at the same time (e.g. never use this option
- in a cron script).
-
--aggressive::
Usually 'git-gc' runs very quickly while providing good disk
space utilization and performance. This option will cause
persistent, so this option only needs to be used occasionally; every
few hundred changesets or so.
+--auto::
+ With this option, `git gc` checks whether any housekeeping is
+ required; if not, it exits without performing any work.
+ Some git commands run `git gc --auto` after performing
+ operations that could create many loose objects.
++
+Housekeeping is required if there are too many loose objects or
+too many packs in the repository. If the number of loose objects
+exceeds the value of the `gc.auto` configuration variable, then
+all loose objects are combined into a single pack using
+`git-repack -d -l`. Setting the value of `gc.auto` to 0
+disables automatic packing of loose objects.
++
+If the number of packs exceeds the value of `gc.autopacklimit`,
+then existing packs (except those marked with a `.keep` file)
+are consolidated into a single pack by using the `-A` option of
+`git-repack`. Setting `gc.autopacklimit` to 0 disables
+automatic consolidation of packs.
+
+--quiet::
+ Suppress all progress reports.
+
Configuration
-------------
kept. This defaults to 15 days.
The optional configuration variable 'gc.packrefs' determines if
-`git gc` runs `git-pack-refs`. Without the configuration, `git-pack-refs`
-is not run in bare repositories by default, to allow older dumb-transport
-clients fetch from the repository, but this will change in the future.
+`git gc` runs `git-pack-refs`. This can be set to "nobare" to enable
+it within all non-bare repos or it can be set to a boolean value.
+This defaults to true.
The optional configuration variable 'gc.aggressiveWindow' controls how
much time is spent optimizing the delta compression of the objects in
the repository when the --aggressive option is specified. The larger
the value, the more time is spent optimizing the delta compression. See
-the documentation for the --window' option in gitlink:git-repack[1] for
+the documentation for the --window' option in linkgit:git-repack[1] for
more details. This defaults to 10.
+The optional configuration variable 'gc.pruneExpire' controls how old
+the unreferenced loose objects have to be before they are pruned. The
+default is "2 weeks ago".
