git-lost-found
GIT-LOST-FOUND(1) Git Manual GIT-LOST-FOUND(1)
NAME
git-lost-found - Recover lost refs that luckily have not yet been pruned
SYNOPSIS
git lost-found
DESCRIPTION
NOTE: this command is deprecated. Use git-fsck(1) with the option --lost-found instead.
Finds dangling commits and tags from the object database, and creates refs to them in the .git/lost-found/ directory. Commits and tags that
dereference to commits are stored in .git/lost-found/commit, and other objects are stored in .git/lost-found/other.
OUTPUT
Prints to standard output the object names and one-line descriptions of any commits or tags found.
EXAMPLE
Suppose you run git tag -f and mistype the tag to overwrite. The ref to your tag is overwritten, but until you run git prune, the tag
itself is still there.
$ git lost-found
[1ef2b196d909eed523d4f3c9bf54b78cdd6843c6] GIT 0.99.9c
...
Also you can use gitk to browse how any tags found relate to each other.
$ gitk $(cd .git/lost-found/commit && echo ??*)
After making sure you know which the object is the tag you are looking for, you can reconnect it to your regular refs hierarchy by using
the update-ref command.
$ git cat-file -t 1ef2b196
tag
$ git cat-file tag 1ef2b196
object fa41bbce8e38c67a218415de6cfa510c7e50032a
type commit
tag v0.99.9c
tagger Junio C Hamano <junkio@cox.net> 1131059594 -0800
GIT 0.99.9c
This contains the following changes from the "master" branch, since

$ git update-ref refs/tags/not-lost-anymore 1ef2b196
