Programmers and software developers lost the plot on naming their tools

> grep (global regular expression print), awk (Aho, Weinberger, Kernighan; the creators’ initials), sed (stream editor), cat (concatenate), diff (difference). Even when abbreviated, these names were either functional descriptions or systematic derivations.

If you asked someone unfamiliar with unix tools what they thought each of these commands did, diff is the only one which they would have even the slightest chance of guessing. It's ridiculous to complain about "libsodium" and then hold up "awk" as a good name.

Awk is short, easy to pronounce, and difficult to confuse with anything else. It's nearly as perfect as a name can be.

You seem to have confused the concept of a "name" with that of a "description". The whole point of names is that they aren't descriptive.
