## Show single file from another branch
git show [branch]:[pathtofile]

# show file history from across all branches

# Find branch with commit
git branch --contains [commit]
git reflog show --all | grep a871742
# git reflog show is actually just an alias for git log -g --abbrev-commit --pretty=oneline, so if you want to fiddle with the output format to make different things available to grep for, that's your starting point!
