Re: nomatch/cshnullglob problems

Hi Bart

Thanks for your explanations.

The script is being used in bash and zsh, and I'd rather not introduce
any Z shellisms such as the (D) qualifier.  When I run the script
normally, it is inside an "emulate -L ksh", so there's no big problem.
I think adding a dummy wildcard to the list might be the simplest

Would you believe I had set "nonomatch" in tcsh, so tcsh was in a sense
emulating ksh, while zsh was emulating csh!  (This explains why I wasn't
getting an error with the equivalent foreach loop in tcsh.)

"Fatal" was the best short way I could think of describing the
behavior. :-)

Under what circumstances should sourcing of a script short-circuit?  A
very simple script such as:
echo start
echo finish

echoes "finish" and runs to completion when sourced, yet:
echo start
echo /nosuchfile*
echo finish

exits before echoing "finish".

It seems to be only if a pattern fails, which doesn't seem all that
useful!  It's also disappointing that bash and zsh differ in this

Can I suggest a simple patch to the manual such as the following:
--- builtins.yo 20 Mar 2006 11:06:24 -0000      1.84
+++ builtins.yo 31 Mar 2006 11:04:47 -0000

I hope the mark-up is correct.  I don't speak YODL. :-)
