How do I close a file in git editor?
After writing commit message:
Esc
write :wq (which means “write and quit“) or :wq!
Enter to close the unix file.
Any file may be opened in any editor. So run
“ps -ax|grep vim”
to check which file is opened in which editor. And then run kill id-of-editor . For e.g.
“kill 12345” Thats all
