tee isn't exactly the opposite of cat but I can't remember a command that only redirects screen output to a file.
What is up, tee?
edit: what's the opposite of "cd .."?
-
cat is for concatenating files, so the opposite would be something that breaks a stream up into multiple files.

Oh, you use Arch?
-
Heh, no, but they do have a nice set of man pages and other documentation online. I prefer NixOS. Easier keeping track of configuration, easier rolling back of (and experimentation with) new stuff.

Hah, forgot about tac
-
I mean... it's nice that it exists and all, but I can't really think of many useful usecases.
-
I think I only ever used it in an intro to shell scripting where we (almost) recreated the function of tail
-
Something like
tac | head | tac, I guess? Yes, that's a valid use case indeed :)

tacis a real command and does exactly what you think it is

How about tac which prints lines but last to first.
-
It prints to stdout. I’d say the opposite is read, which reads from stdin.
-
Hmm, maybe pwd?
-
-
There’s pushd where the opposite is clearly popd.
