[lug] My script work on real "ksh" but not "bash"

[Dave Pitts]

Hello:

I've got a script (below) that works as expected under the Korn Shell 
(ksh) but fails under Bash. It acts as if the variables have some kind 
of scope issues as they are null after exiting the loop.

It's probably something simple; but I can't see the problem...

The script:

#!/bin/bash
typeset srclist=""
typeset tarlist=""

if [ "$1" = "" ];then
   echo "Usage: $0 statusfile"
   exit 1
fi
cat $1 | while read line
do
    if [ "${line}xx" = "xx" ]; then
      break
    fi
    tag=`echo $line | awk '{print $2}'`
    if [ "${tag}xx" = "Volume:xx" ]; then
        while [ "$line" != "Component Volumes:" ]
        do
           read line
        done
        endline=""
        while [[ -z "${endline}" ]]
        do
            read line
            if [[ "$?" -ne 0 ]]; then
                echo "ReadStatusFailed:"
                exit 1
            fi
            case "${line}" in
                *\ SOURCE\ *|*\ SOURCE)
                    srcvol=`echo $line | awk '{print $1}'`
                    ;;
                *\ UPTODATE\ *|*\ UPTODATE)
                    tarvol=`echo $line | awk '{print $1}'`
                    endline="TARGET"
                   ;;
                *\ SCRATCH\ *|*\ SCRATCH)
                    endline="TARGET"
                   ;;

            esac
        done
        srclist="$srclist $srcvol"
        tarlist="$tarlist $tarvol"
    fi
    echo "inloop: srclist = " $srclist ", tarlist = " $tarlist
    echo "    srcvol = " $srcvol ", tarvol = " $tarvol
done
echo "outloop: srclist = " $srclist ", tarlist = " $tarlist
if [[ -z "${srclist}" ]]; then
   echo "IT's BROKE"
else
   echo "It worked"
fi
exit

The data:

Group Volume:     Vol1
Component Volumes:
   /dev/dasdc1                SOURCE
   /dev/dasdc2                UPTODATE


So, if anybody sees an issue here. Please let me know...
Thanks.

PS. re: System Load - I FINALLY got it all to work after they replaced 
the disk drive and found some wrongly placed jumpers on the motherboard.
