We used to speak of a great Unix systems programmer as someone who could write device drivers with cat and have them compile and run the first time.

- siltpotato 6y agoBefore I look up `man cat`, what can you do with `cat` other than just see what's in a file?
- Crespyl 6y agoWhen not given a file, cat will just read from stdin, so you can use "cat > file.c", write some text, and send EOF with ^D when you're done. Obviously, there's no way to go back and edit anything mid-stream, you have to write the whole thing out in one shot.
- amyjess 6y agoYou can join files together. $ cat foo bar > baz will join the files foo and bar together into a single file called baz
