9SYNOPSIS
10--------
11[verse]
12'git prune' [-n] [-v] [--progress] [--expire <time>] [--] [<head>...]

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 an 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].

59EXAMPLES
60--------
61
62To prune objects not used by your repository or another that
63borrows from your repository via its

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.
