Imagine a single-app computer that reboots and tees every character you type both to the foreground application and to the shell … as root.
JWZ links to the goods:
Yeah, uh, ‘oops.’
Well, that's a big fum-ducker all-righty. But what is this 'Tee'?
tee - read from standard input and write to standard output and files
So I could do this?
ls -la | tee file.txt | more
I must lack curiosity or something - if I'd ever heard of this I have no recollection of it. Seems blazingly obvious in hindsight - if you can pipline you surely can stick in a T join.
And I can think of some shell scripts I use that really need to be refactored.
