I've been using bash for years, and along with a coworker, we could not figure out how create and use a variable based on........ err. well here's what i'm trying to do.

something like this...

for each in 81 82 83 84 ; do
  IP_${each}=$(nmap -sV -v -v -O 192.168.2.$each)

then somehow I want to be able to use $IP_$each but of course bash doesn't like this.

Can anyone help me out?

Hint:  look at `eval'.  For instance:

        eval IP_${each}=\$(nmap -sV -v -v -O 192.168.2.$each)
