Try something like this:
open NETSTAT, "netstat -I hme0 $SLEEPTIME |" or die "Can't start netstat: $!\n";
Then, just read from the NETSTAT filehandle.
For more information, look at 'open' and 'sysopen' in the Camel book.
Also, you may want to consider using 'select' if you don't want to block
on reads. (Be sure you look at the 'ready file descriptors' version of
'select').
