[ale] Baffled on doing CASE statement with a Variable list of values

[Lightner, Jeff]

You sent this before the email I just sent that talks about while loop?

Perhaps I didn't make it clear enough.   Yes, the first approach of hard coding case values works.

All the other approaches of trying to put the values in a variable do not work.

This works:

#!/bin/bash

FRED='one'

case $FRED in
  one|two|pie) echo "got ${FRED}"; ;;
  *) echo "crud"; ;;
esac

Exactly how does not assign a list of values separated by pipe to use that variable later on in a script and make a CASE statement happy?
The script below shows a variety of attempts.

Ultimately, we're aiming to grab the list from a file, eg "LIST="`cat allow.list`"

REMOTE_ADDR=one

case $REMOTE_ADDR in
        one|two|three) echo "I like $REMOTE_ADDR" ;;    # Picks this one.
        *) echo "I do NOT like $REMOTE_ADDR" ;;
esac

LIST="one|two|three"
case $REMOTE_ADDR in
        $LIST) echo "But now I like $REMOTE_ADDR" ;;
        *) echo "But now I do NOT like $REMOTE_ADDR" ;; # Picks this one.
esac

case $REMOTE_ADDR in
        "$LIST") echo "And I like $REMOTE_ADDR" ;;
        *) echo "And I do NOT like $REMOTE_ADDR" ;;     # Picks this one.
esac

LIST="one"
case $REMOTE_ADDR in
        "$LIST") echo "Yet I like $REMOTE_ADDR" ;;      # Picks this one.
        *) echo "Yet I do NOT like $REMOTE_ADDR" ;;
esac

LIST="one\|two\|three"
case $REMOTE_ADDR in
        $LIST) echo "However now I like $REMOTE_ADDR" ;;
        *) echo "However now I do NOT like $REMOTE_ADDR" ;;     # Picks this one.
esac

Every time you stop a school, you will have to build a jail. What you

gain at one end you lose at the other. It's like feeding a dog on his

own tail. It won't fatten the dog.
