Complex Command Lines
  Let's find how many SSH sessions to the local machine exist.
  Find our own IP address:
    $  ifconfig eth0 | head -2
    eth0      Link encap:Ethernet  HWaddr 00:10:F3:02:15:00  
              inet addr:192.168.1.200  Bcast:192.168.1.255
    $ ifconfig -a | grep 'inet addr'| head -1  \
         | awk -F: '{print $2}' | awk '{print $1}'
    192.168.1.200
    $ myip=`ifconfig -a | grep 'inet addr'| head -1 |
         awk -F: '{print $2}' | awk '{print $1}' `
