I am getting some weird output on trying to do diff between HEAD and last commit
Fatal: ambiguous argument 'head^': unknown revision or path not in the working tree.
use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'
While using git diff <sha> HEAD^
, I get the error
warning: ignoring dangling symref head. warning: ignoring dangling symref head.
fatal: ambiguous argument 'head^': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'
am I missing something?
Okay, I think there can be 2 possible reasons here
1) Issue here is, you are trying to do a git diff <sha> head^
In this case, you need to correct your command to git diff <sha> HEAD^
. Note the upper case characters. Check out this question to read more about HEAD
.
2) You are trying git diff <sha> HEAD^
and are still getting the error message. In this case, I think you have only one commit in your repository. While the sha
points to that lone commit, your HEAD
also happens to point at that first commit, and HEAD^
happens to point at the commit before that, which doesn't exist, so the error.
Another possibility here is that someone upstream has created a dangling symref
(a dangling object ) while doing a merge or a git reset
or a git rebase
. This should be removable by doing a git prune
.
