Newbie: Submit whole buffer and capture output

[address@hidden]

Hi,

Want to learn Emacs to have a powerful editor on *nix...

I code perl scripts, and I want to find out how to submit a whole
buffer (with a shebang at top) to the shell and capture the output
somewhere in Emacs -- probably the *command shell* window, which I
know nothing about other than the name.

Can someone point me in the right direction?  Googling hasn't helped
me here...

tia,
Matt
