Problem with nested foreach
kk_...@yahoo.com
I'm finding that if the inner "foreach" has no match, my script is
terminating with a "foreach: no match" message. Is this normal? Is
there a way to continue with the outer loop if the inner loop has no
match?
The script looks like this:
*********
set main_dir = `pwd`
foreach sub_dir (`find . type d -name UNIT_TEST -print`)
cd $sub_dir
foreach file (*.ut)
echo $file
end
cd $main_dir
end
echo I am done!!!!
*********
Eventually, this will get more meaty, but first I wanted to find out
how to handle this situation.
Thanks!

You might want to take a look at question 17 in the FAQ
(http://home.comcast.net/~j.p.h/cus-faq-2.html#17) before continuing to
write csh scripts.

If there is no match, the loop will be executed once, with the variable
equal to the wildcard pattern.

Danger, Will Robinson! I've been there. The more you program in the C
shell, the more headaches you will have. That's why I wrote

Yes. You can set the special variable
set nonomatch
and you will not get an error, but ...
> foreach file (*.ut)
> echo $file

In this case, file will be "*.ut"
You have to test for this condition.
I think there was other work-arounds, but it's been years since I had
to deal with them.
