What does ^{} mean in git?

Question

I stumbled upon two odd characters at the end of a git ls-remote command and I wonder what this means?

Answer 1

Note that git ls-remote has new filter with git 2.8 (March 2016).

See commit 99c08d4, commit ba5f28b, commit 80b17e5, commit 40a8852, commit 54813bd (18 Jan 2016) by Thomas Gummerer (tgummerer).

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.
