Bug in git-completion.bash in __git_heads() function

Amandeep Gautam· Dec 4, 2017, 09:16 UTC · lore

Hello,
   This is the first time I am sending a bug report here, so if I have
not met the criteria please let me know.
   I found that at:
https://github.com/git/git/blob/master/contrib/completion/git-completion.bash#L371,
the usage of refname:strip=2 generates error:

fatal: unknown refname: format strip=2.

I am using git version 1.9.1. However using %(refname:short), I believe produces intended behaviour.

If my findings are validated, I would be willing to submit a patch for this. Please let me know.

Regards, Aman

The for-each-ref format modifier ':strip=<N>' was introduced in v2.7.1~15^2 (tag: do not show ambiguous tag names as "tags/foo", 2016-01-25) and the completion script started using it in v2.13.0-rc0~46^2~8 (completion: don't disambiguate tags and branches, 2017-03-23).

It seems you're using an old Git with a recentish completion script. You could either upgrade Git, or use the completion script that was shipped with it.
