if you want to capture the output from the
ping command, in Windows XP, you might want to try something like this:
use warnings;
use strict;
# capture the output from ping
my $ping = qx( ping -n 4 127.0.0.1 );
# extract the values
$ping =~
m/
.*
Sent \s = \s (\d+)
.*
Lost \s = \s ([\d\.]+) \s \( ([\d\.]+) % \s loss
.*
Average \s = \s ([\d\.]+) ms .*
/sx
;
my $sent = $1;
my $loss_no = $2;
my $loss_proc = $3;
my $average = $4;
print "Lost $loss_no packets from $sent packets ( $loss_proc % ). ",
"Average RTT $average ms.\n";

the regular expressions tutorial.
