You can run commands from perl using system and backticks. If that's not what you want, what command line shell do you use? (And that's not a Perl question this way.) For example, passing STDOUT of Perl program as an argument to another program looks like this in a POSIX shell: ./c-program "$(perl -e "whatever")".

Edit: corrected a typo.
