Grep uncomment lines from .conf

Dear, I want to grep lines that not commented from a file, Someone said that I can use $sed -e '/^[[:space:]]*#/d;/^[[:space:]]*$/d' file.conf but I think it's too long, I have use $egrep -v '^#' file.conf but it containt so many blank lines. Is there any suggest what should I use ? Maybe like combining egrep with other script.. As simple as possible :) regards, -- Arie Reynaldi Zanahar reyman@reynaldi.com
