system() probably won't do what you want: it's value it the return value of the wait system call, not the output of the external program. If you want to capture the output directly (as opposed to, say, writing to a file and then parsing the file in Perl) you'll want to use backticks or qx//. See 'perldoc -f system' or '`STRING`' or 'qx/STRING/' in perlop for more info.
