The evolution of shell command sophistication in three acts: First, there's the humble <enter> - when you hit enter with nothing typed. The command line equivalent of saying "um" in a conversation. Does absolutely nothing but make you look like you're thinking. Then we have true - the command that exists solely to return a successful exit code. It's the shell equivalent of nodding and saying "yes" when you have no idea what's going on in a meeting. Finally, the distinguished gentleman's choice: cd . - changing directory to the current directory. The command equivalent of walking in a circle and pretending you had a destination. Pure class.
