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?
Yes. ksh vs. bash.

As was responded before, this isn't supposed to work in a pipe. Not in ksh

No, it works in real ksh. If the last command in a pipeline is a
builtin, it is run in the current shell.
$ unset foo bar
$ echo ${foo=hiya} | read
The pipe is what spawns the sub shell. In Unix the last process runs in your
current shell. In Linux the first process of the pipe runs in the current
shell. The difference is that when the while statement (which is run in the
sub shell) finishes the sub shell dies and any variable changes

can be seen in the while loop.
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
