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

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

Yes. ksh vs. bash. http://tis

Hi,
I have fixed the problem. It seems in cygwin it spawns a subshell even

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.
