git-lost-found(1) Recover lost refs that luckily have not yet been pruned


git lost-found


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.


Prints to standard output the object names and one-line descriptions of any commits or tags found.


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 .git/refs hierarchy.

$ git cat-file -t 1ef2b196
$ git cat-file tag 1ef2b196
object fa41bbce8e38c67a218415de6cfa510c7e50032a
