Linux commands are often based on a series of obscure pins dating back decades. For example nano, from 2001, is a pun on pico, the Pine (email) Composer from 1989, and pine is a pun on Elm, from 1986, which is in turn a pun on The Nightmare on Elm Street (1984).
Don't go to sleep
Logically, the next simple editor would be named Atto, which is why it will be named gimli (Nano means dwarf)
The name dwarf can’t be used directly of course because it is the debugging symbol format for ELF
Except dwarf is out of date and has been replaced by orc As far as I know, hobbit is still available
grep is a fun one youtu.be/NTfOnGZUZDk?...
And "less" is from "less is more" where "more" was the pager on earlier unices :D
