So few of us use physical tapes these days, but the "tape archive" (tar) remains ubiquitous.

Not entirely unserious: "awk" is a good name because it is three characters to type "rg" is better than "grep" because it is two fewer characters type

There's a reason why the basic Unix file commands are ls, cp, mv, rm.

They're easy to type on a TTY.

grep is from the ed command "g/re/p" which is g (all lines, short for "1,$") /re/ regular expression to search for, "p" to print the lines.

It still works in vi.

I would if they weren't so outrageously expensive (tapes and tape drives ;))
