Remove superfluous from conf file

sed -re '/^#/d ; s/#.*$// ; /^\s*$/d'
Use it with cat and '|' for know what is used in a conf file. For example cat /etc/squid/squid.conf | sed -re '/^#/d ; s/#.*$// ; /^\s$/d' : Show you what you use in your file conf. It removes all comments and empty lines. Empty lines are lines with nothing, a tab, or a space.
