[Novalug] need grep help

[Jay Hart]

I like to search config files with the comment lines removed. So I thought

more filename | grep -v "#"

would remove any line starting with a "#" character

However it seems to actually remove any line with a "#" on the line,
regardless of placement (or something similar to this behavior).

I've seen some examples online to remove lines if the first char is a #, but
not for example if the line is indented, but still a comment.

What I'm really looking for is a grep that will remove all comment lines, or
lines that are blank.

This:

grep -v '^$' filename |grep -v "#"

doesn't quite get me there.

Can I get some pointers on this.
