RE: Can't set variables in a while loop that is passed to the rest of the script.

[Damo, David]

Hi,

I have fixed the problem. It seems in cygwin it spawns a subshell even under 
bash. I used a for loop instead and everything worked nicely.

for line in `sed 's/\$/^/g' $propfile`
do
        nvpair=$(echo $line | awk -F"=" '{print $1,$2}')
        set -- $nvpair
        if [ ! "$1" = ""  ]; then
                eval "$1"=\"$2\"
        fi
done

Hi,

I had a script that worked on UNIX, but on Cygwin it does not work. When I set 
a variable in a while loop I can't use it after the loop. However, this worked 
in UNIX. Any ideas why? All variables set after the done command are blank, but 
can be seen in the while loop.

propfile=${SCRIPT_HOME}/${propfilename}
sed 's/\$/^/g' $propfile | while read line
do
        export david="Hello"
        nvpair=$(echo $line | awk -F"=" '{print $1,$2}')
        set -- $nvpair
        if [ ! "$1" = ""  ]; then
                eval "$1"=\"$2\"
        fi
done

echo $david

echo "Setting siteminder_home"
echo $siteminder_home

Thanks,

David
