Surely, many people have heard (but it is worth reminding) about
thefuck utility – a great tool for fixing errors in the previous command (in the terminal).

My favorite example:
git push fatal: The current branch master has no upstream branch. To push the current branch and set the remote as upstream, use git push --set-upstream origin master $ fuck --yeah git push --set-upstream origin branch_name Total 0 (delta 0), reused 0 (delta 0) ...
Quite an extensive list of what commands
thefuck can fix: https://github.com/nvbn/thefuck#how-it-works
