I need help deciphering what is being said here:export IP=`/sbin/ifconfig | grep 'inet addr:'|grep -v '127.0.0.1'|    cut -d: -f2 | awk '{print $1}'`I know it is to set IP as an environment variable, but other than that, what does everything else mean?  Is there a manual on this?Thank you.
Need help deciphering unix statement
environment variables
It's going to list all of the non-loopback IP addresses on the system. Assuming you only have one non-loopback IP address on this box, it's going to export the IP address of the system to the environment variable IP.Start by running the pipeline one section at a time. Meaning, first run/sbin/ifconfigto see what it does. Then run .../sbin/ifconfig | grep 'inet addr:'and keep going from there.
