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.
