How to abort a git rebase from inside vim during interactive editing

Solution 1:

If you exit the editor with an error code, the rebase will be aborted.

To exit with an error code on vim, do

:cq

See here and vimdoc here.

Just delete all the lines that are not comments from the file. Then save it to the default supplied path and exit the editor.

As a result git will just do nothing in this rebase.

To delete all lines in vim you can use

:%d|x

Then save and quit.
