It is an implementation detail that a new tag is created by adding a file in the .git/refs/tags directory. The only thing the user needs to know is that a "git tag" creates a ref in the refs/tags namespace, and without "-f", it does not overwrite an existing tag. Inspired by a report from 乙酸鋰 <ch3cooli@gmail.com>; I think I caught all the existing mention in Documentation/ directory in the tip of 1.7.9.X maintenance track, but we may have added new ones since then.

NAME

|
----
|
|
git-lost-found - Recover lost refs that luckily have not yet been pruned
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'git lost-found'
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
|
|
*NOTE*: this command is deprecated. Use linkgit: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.
|

|
|
|
|
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.
