I use cat a lot. It allows me to remember less switches of other commands, and simplify syntax of complex commands (pipes chain)

I treat cat as a stream-fier: given a file it creates a stream on stdout

BTW Is it true that the origin of cat name is that in slang to cat means to vomit ? (to vomit a file to stout) ? This is what I always known, but recently I read that cat stand for conCAT

I prefer cat as vomit....
