cat (as in concatenate)
prints a file to stdout

head & tail print the beginning / end of a file

Less is more.

Not so much of a joke as a cute story. There was once a programmer with a dog named Biff who would bark at the mailman every time he delivered the mail. The programmer wrote a program to monitor incoming email and beep when you got a message, and named it biff.

my favorite name origin for a bit of software relates to the text editor nano. nano was written as a standalone clone of Pico, as a play on metric prefixes, but Pico is actually Pine compositor, part of Pine, an email client. Pine itself was based on an earlier email client called Elm, and has been attributed as various recursive acronyms such as 'Pine Is Nearly Elm'

What? and I am a programmer 😅
