Maybe the idea is that every shell script compromised of existing, simpler commands, is automatically itself a "command" in UNIX. Obvious and simple today, but not a common concept when this video was made.
- TomMarius 6y agoWasn't that the same in operating systems like MS-DOS and its predecessors, and on Apple computers as well?
