I think what you are looking for is "call-process" and "start-process".

Evaluating

  (call-process "ls" nil t t "-l")

for example, you get the current directory listing in long form inserted
at point into the current buffer.

(call-process waits for the process to terminate, while start-process
just lets the process run while Emacs goes on with its other tasks).

There are so many options and variants that I'll stop here and refer you
to the documentation -- but do ask here if you get stuck.
