I remember going into my networking unit and absolutely destroying it through the use of the command line. Everyone else was clicking through the wireshark GUI and I just grepped every answer. Finished the hour long practical assessment in about 15 minutes having run everything twice.

CLI is so valuable because rather than explore a presentation of the data you plan your RE etc and then run it and it either returns the answer or it doesn't.

There are some TUIs I quite like (LNAV as a pager) but I think if you really know what you're dealing with the CLI is better almost every time.
