Umm, no, chaining together 5 or more somewhat arcane single-purpose tools is the unrealistic solution here. If the article was about using ls to just list files, and I had said "actually you should use Python's os.listdir() and fi

I mean, the example you gave of what you use ssh for is itself an obsolete function. Using a personal Unix server to host a personal website is not really any different than making your own clothes using a sewing machine. It is perfectly fi

Yes, but the number of sysadmins in the world is converging rapidly to zero. Mainly because the invisible overhead of having your boxes managed by people who use sed and awk is much higher than the alternatives (containerisation, cloud vend

Most of the justifications for using collections of command-line Unix tools are no longer valid today. Instead you should be using a proper programming language. Note that people who still do use complex solutions built from cat, head, cut,
