zsh filename expansion in ksh mode

[Jerry Rocteur <jerry.rocteur@xxxxxxxxx>]

Hi,

I have a problem with filename expansion when I'm in a script.

filename=/tmp/xxx.*([0-9)].log

If I run

           ls $filename

This works fine.

But if I run this from a script
         egrep bla $filename

I get invalid filename

What option could the admins be loading up when I run a script that
disables my filename expansion.

NOTE: I was looking for a way to look for a filename that contains an
unknown number of numbers *([0-9]) works well at the command line.

ZSH_VERSION 2.6 (Redhat 5)
/bin/ksh is linked to /usr/zsh and the first lien of the script must
be #!/bin/ksh

I'm looking for a work around if possible.

Thanks in advance,

Jerry
