grep using regexp

I have 2 files called stuff-egress-filter and stuff-ingress filter. There are also files called something like stuff-egress-F/0

I want to match the first two... I tried (i realize there is no filename... I'm piping this from the ls command)

Code:
grep stuff-[ei]*-filter

Finds nothing. If I type

Code:
grep stuff-[ei]gress-filter

..it finds just the egress (no match for the n in ingress).

Can I not use the asterisk in this case?

Why don't you use
Code:
grep stuff*filter

Good thought. I was making it more difficult.

However, stuff*filter finds nothing.

It's like it's taking the * literally.

The really weird part... my whole command looks like this:
Code:
ls -al stu* | awk '{print $6,$7,$8,$9}'

and the output of that is:
Code:
May 10 01:12 stuff-egress-F0-0
Jun 27 03:30 stuff-egress-filter
Jun 27 12:14 stuff-ingress-filter

so the * wildcard works there... but then if I pipe that through | grep stuff*filter..... finds nothing.

try using quotes ... use
Code:
grep "stuff*filter"

No go... still no output.

Also tried it as
Code:
ls -al stu* | awk '{print $6,$7,$8,$9}' | grep "stuff*filter" > testgrep

testgrep is empty.

if you want a quick solution here it is

Code:
ls |egrep "stuff|gress|filter"|grep -v "\-F"

Yeah kamitsin, that's how I've been doing it... I was just curious as to why it wouldnt work with the * wildcard. I thought I was going to post the question and then have someone show me something very easy I was missing...

I'll continue to do the workaround until someone can show me why the * isnt working.
