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

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. http://tiswww.case.edu/php/chet/bash/FAQ, E4. Not
cygwin-specific.
As was responded before, this isn't supposed to work in a pipe. Not in ksh either, I think, and I tried it, with ksh on a Sun and pdksh on cygwin.
So I don't think this is a ksh vs bash issue.
David, maybe you happened to have set the variable you checked before callling the script already?
