You don't, at least, not with system(). system() doesn't return its
output, it returns its exit value. If you want to capture the output of a
program, use backticks (``) or the qx() operator. Or consider using
open() like so:
open PING, "ping -s localhost 56 1 |"
or die "can't spawn ping: $!";
while (<PING>) {
print "got: $_";
}
close PING;
As someone mentioned, make sure you tell ping to stop after a certain
count, if it doesn't do so automatically. If you don't, then you won't be
able to stop it (unless you use the open() method above, and put a 'last'
in the while loop somewhere).
But have you considered using the Net::Ping module?
