Shell Programming and Scripting

I'm trying to create what (should be) a simple bash script that will pull computer name and use that info to bind to one of three servers. Is there any way to do this without having a text file with the names of the servers and associated computer names?

Could you provide more detail, where do you hope to pull the server name from? reverse DNS look-up (if you have the IP), use nmap to map the network and see what's attached to a given machine? randomly generate hostanmes until we hit a node that responds with some specific telltale?

Without some context the question is difficult to answer

the server will be chosen based on the physical location of computer in our network which is indicated in ComputerName. ex= xyz-location all xyz computers would be bound to certain replica. This is my feeble attempt so far.


#!/bin/sh

COMPUTERNAME=`scutil --get ComputerName`

if [[ $COMPUTERNAME = *abc* ]]; then
echo "works"

fi

this part works, but I need to add more variables in the list than just abc

Code:

case "$COMPUTERNAME" in
   "") echo "empty ???" ;;
   *abc*|*xyz*) echo "ok" ;;
   [0-9][A-C].txt) echo ok ;;
   [Aa][0-9]*.jpg) echo ok ;;
   *) echo not so ok ;;
esac

Code:

echo $COMPUTERNAME | egrep '(abc|def|xyz)' >/dev/null && echo "This works to"

It works! Thanks I really appreciate it.
