The human brain finds unexpected or weird words a lot more memorable than expected words.
grep is better than find "find-regular-expression"
awk is better than "execute-command-on-regular-expression"
perl has nothing to do with pearls
If it's a common command, concept, function, etc. that appears in may places, give it an odd name!
Document it thoroughly!
And don't go overboard. When everything is special, nothing is, with the added disadvantage that nothing is "readable" either.
