I've recently discovered useful Git configuration snippet which I now use daily as a means temporal backup before pulls & merges.
Snippet credits goes to justinmk.
Here it goes.
[alias] autosave = "!git stash save autosave-$(date +%Y%m%d_%H%M%S)"
How to use:
λ ./til/ master* git autosave Saved working directory and index state On master: autosave-20160207_191131 HEAD is now at 08efc4b Initisal version of README λ ./til/ master git stash apply
