Use backticks and $?. From perldoc
perlvar:
$? - The status returned by the last pipe close,
backtick (``) command, or system() operator. Note that this
is the status word returned by the wait() system call (or
else is made up to look like it). Thus, the exit value of
the subprocess is actually ($? >> 8), and $? & 127 gives
which signal, if any, the process died from, and $? & 128
reports whether there was a core dump. (Mnemonic: similar
to sh and ksh.)
