Re: Suppressing failed glob patterns

I like the default in zsh for failed glob patterns (which errors when no 
file matches the pattern).

For example:
% rm file1.* file2.*
zsh: no matches found: file1.*
zsh never executes rm (which is fine). Additionially I would like to get rid of the error message in a script. Unfortunately redirecting stderr does not work (because rm is never executed). Is there a way to keep the 
default and to suppress the error?!


Check these settings: <http://zshwiki.org/home/options/expn>

And also see what the difference between

 % echo non-existing-file.*
and
 % echo non-existing-file.*(N)

is.

That's documented in 'man zshexpn' and a list of available modifiers
and flags is also in <http://www.bash2zsh.com/zsh_refcard/ refcard.pdf>. 



You could use setopt no_nomatch and then rm would run, you'd get this:

% rm nowayjose*
rm: nowayhoe*: No such file or directory

Then you could redirect STDERR:
% rm nowayhoe* 2> /dev/null

[no error]
