I have a bash shell pattern that works, but I can't get it to work when called from perl.

This pattern works in bash shell, but seems remarkably resistant to incorporate into perl -- 

echo mc-lang-+([^-])-+([^-])*.rpm<br>

[download]
(matches mc-lang-4.6.1-140.x86_64.rpm)

a "previous expression, like
echo mc_lang-4.6.1-140*.rpm works from perl with
$a=`echo mc_lang-4.6.1-140*.rpm`
--if the file isn't there, I get back the "*", (unexpanded), otherwise, I get:
mc-lang-4.6.1-140.x86_64.rpm

but the top expression, a bit more precise and what I want fails 13 ways from thursday.

Double quotes, single, adding bash -c 'echo...' in the backquotes, extra backslashes in front of the problematic parens. Part of the prob was I needed to set the extglob option (shopt -s extglob; echo <pattern>).

But every type of backslashed sequence either doesn't expand, or comes up completely empty, or errors pop out.

Why can't perl pass a simple shell pattern and have it expanded!

A work-around that I would prefer not to use that I _think_ would work would fork bash as a process with I/O connected to sockets but that seems like pathetic overkill.

Is there something I'm missing in this morass? Or do I have to go search for a module to debug and modify... -- which isn't really much preferable to launching bash as a co-process...?

Thanks, Linda
