Hi Chaps

Need some help with this, I’m attempting to try and read in the below which is system output for one of the NIC on my server.

2: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:0c:29:4e:97:a1 brd ff:ff:ff:ff:ff:ff

I want to be able to strip away all characters before eth1 including all white space and eveything after eth1: so I’m just left with eth1.

I have tried various regular expression but can’t seem to trap : unless you can think of a better way to do it.

Then print out back to the file handle just the NIC adapter name

This is what I have so far, not much to go on but should give oyu an idea of what im trying to do

#!/usr/bin/perl -w
my $nicount = `ip link >/tmp/nic.txt`;
open(NICFH, "/tmp/nic.txt") || die "can't open file: $!";
my @NIC = <NICFH>;
foreach my $file (@NIC) {
$file =~ s/\d\:\s//;
print $file;
}
