Time-saving tips for Linux
I don't think these tips are that great.  Some random criticisms:ifconfig is deprecated (use "ip" instead).There is not much value in knowing vim if you know Emacs.  If you want to edit something in your terminal, well, emacsclient -t to your Emacs session.  Or use mg, which is a very fast and light Emacs workalike -- just enough for editing your /etc/apt/sources.list to get Emacs installed :)
