git pull - can't submit merge message [duplicate]
Solution 1:
This is vim, it's a common unix editor
press:
:wq
that's it. (w=write q=quit)
Solution 2:
When you see this, an editor already opened, because you see this ;) I guess it opens vi, or a derivate of this. Google for it to find out how to use it, but it seems you prefer to change the editor instead
git config --global core.editor "emacs"
I prefer nano :)
