=================

NAME
----
git-lost-found - Recover lost refs that luckily have not yet been pruned.

SYNOPSIS
--------
'git-lost-found'

DESCRIPTION
-----------
Finds dangling commits and tags from the object database, and
creates refs to them in .git/lost-found/ directory.  Commits and
tags that dereference to commits go to .git/lost-found/commit
and others are stored in .git/lost-found/other directory.


OUTPUT
------
One line description from the commit and tag found along with
their object name are printed on the standard output.


EXAMPLE
-------

Suppose you run 'git tag -f' and mistyped the tag to overwrite.
The ref to your tag is overwritten, but until you run 'git
prune', it is still there.

------------
$ git lost-found
[1ef2b196d909eed523d4f3c9bf54b78cdd6843c6] GIT 0.99.9c
...
------------

Also you can use gitk to browse how they relate to each other
and existing (probably old) tags.

------------
$ gitk $(cd .git/lost-found/commit && echo ??*)
------------

After making sure that it is the object you are looking for, you
can reconnect it to your regular .git/refs hierarchy.

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