I'm not sure that the article was referring to System Administrators though (I thought that it was about general office duties).
Upon reflection, I think that our Linux intro training should have actually focussed on how to discover the required commands (as mentioned by Paulfx1 above) rather than concentrating on memorizing the basic commands.
"Don't think of the importance of using command line interface tools on Unix-like systems as a problem."
It's not a problem, it's a necessity.
The Terminal, Command Prompt and/or PowerShell shouldn't present any problems, to those who are being paid to work as System Administrators.
I'm not an office worker (or System Administrator).
I've only used "man -k " once in ~3 years of using Ubuntu (I'd forgotten all about the -k option/switch).
My statement about GUIs was about office workers.
Office workers shouldn't have to open the CLIs to do their work.
