Script to get the serial number from the host and the monitor of our Unix machines at work.

getSerials.sh

#!/bin/bash
XORG=${1:-/var/log/Xorg.0.log}
HOSTNAME=`hostname -s`
SYSSERIAL=`sudo /usr/sbin/dmidecode -s system-serial-number`
#SHORTSERIAL=${SYSSERIAL%% *}

/usr/bin/awk -F": " '
    BEGIN {
        sys="'${HOSTNAME}'";
        sysserial="'${SYSSERIAL}'";
    }
    $2 ~ "Monitor name" {
        mon=$3;
        namerec=NR;
    }
    $2 ~ "Serial No" {
        if (NR == (namerec +1))
            monserial=$3;
    }
    END {
        printf ("%s:%s,%s:%s\n",sys,sysserial,mon,monserial);
        exit;
    }' $XORG

I believe Devin Teske was the original author, not sure though.
