I stumbled upon two odd characters at the end of a git ls-remote command and I wonder what this means?
0e4c39557ccb6789173c refs/tags/2011-11-04 966f8df553f18c486820 refs/tags/2011-11-04^{} Do you happen to know what this ^{} means? Also, why does this git tag seems duplicated?
The ^{} notation is explained in the gitrevisions manual:
<rev>^{}, e.g. v0.99.8^{} A suffix ^ followed by an empty brace pair means the object could be a tag, and dereference the tag recursively until a non-tag object is found.
In this case - refs/tags/2011-11-04 is the tag that points to the tag object 0e4c39557ccb6789173c. By doing refs/tags/2011-11-04^{} we can dereference the tag to the final non-tag object, which in this case is - 966f8df553f18c486820 (a commit). Note that ^{} is a noop when applied to non-tag objects.
The git show-ref command can be use to see tags as well as the final dereferenced non-tag objects:
$ git show-ref --tags 3521017556c5de4159da4615a39fa4d5d2c279b5 refs/tags/v0.99.9c 423325a2d24638ddcc82ce47be5e40be550f4507 refs/tags/v1.0rc4^{} $ git show-ref --tags --dereference 3521017556c5de4159da4615a39fa4d5d2c279b5 refs/tags/v0.99.9c 6ddc0964034342519a87fe013781abf31c6db6ad refs/tags/v0.99.9c^{} 055e4ae3ae6eb344cbabf2a5256a49ea66040131 refs/tags/v1.0rc4 423325a2d24638ddcc82ce47be5e40be550f4507 refs/tags/v1.0rc4^{} From the git show-ref manual:
-d --dereference Dereference tags into object IDs as well. They will be shown with "^{}" appended.
Note that git ls-remote has new filter with git 2.8 (March 2016).

That means you can show only the tags with
git ls-remote --refs Do not show peeled tags or pseudorefs like HEAD in the output.
