I've learned that personally one night fighting messed up rebase conflicts and for still unknown reason I copied and pasted a path for `rm` and ended up issuing `rm -rf ~ /repo-path /unneeeded-dir` - it took me a couple of seconds to realize that this command takes unexpected long time to execute and then my eye caught a view of Finder window with shrinking list of folders in home directory :) Time Machine helped me quite a lot but unfortunately with a nasty surprise that it doesn't backup dot files :-/ Lessons learned.
