Question

I don’t know the best way to form this question, but here’s the code I want to work:

case $MESSAGE in
    ?Trcx!~*PRIVMSG*[${Nick}|${AltNick}]*[nN][mM]ap*)
       echo "Some Code";;
     *)
       echo "Some Other Code";;
esac

How would I make it work? The part that is not working is the [${Nick}|${AltNick}] I want the expression to be valid for both the $Nick and $AltNick var. Any help is greatly appreciated!

Bash glob patterns are documented here.
You want this: @(patt1|patt2).
Note the extglob shell option must be enabled.

shopt -s extglob
case $MESSAGE in
    ?Trcx!~*PRIVMSG*@(${Nick}|${AltNick})*[nN][mM]ap*)
       echo "Some Code";;
     *)
       echo "Some Other Code";;
esac
