6 git-lost-found - Recover lost refs that luckily have not yet been pruned
8 SYNOPSIS
9 --------
10 'git-lost-found'
12 DESCRIPTION
13 -----------
14 Finds dangling commits and tags from the object database, and
15 creates refs to them in the .git/lost-found/ directory.  Commits and
16 tags that dereference to commits are stored in .git/lost-found/commit,
17 and other objects are stored in .git/lost-found/other.
20 OUTPUT
21 ------
22 Prints to standard output the object names and one-line descriptions
23 of any commits or tags found.
25 EXAMPLE
26 -------
28 Suppose you run 'git tag -f' and mistype the tag to overwrite.
29 The ref to your tag is overwritten, but until you run 'git
30 prune', the tag itself is still there.

36 ------------
38 Also you can use gitk to browse how any tags found relate to each
39 other.
41 ------------
42 $ gitk $(cd .git/lost-found/commit && echo ??*)
43 ------------
45 After making sure you know which the object is the tag you are looking
46 for, you can reconnect it to your regular .git/refs hierarchy.
