Stripping comments from a file

You can run this command to strip comments (line starting with a #) and empty lines from a file in Linux:

cat /etc/squid/squid.conf | grep -v ^# | grep -v ^$

I usually run this command on squid.conf, a file heavily commented.

To save the lines to file squiD.conf, you can run:

cat /etc/squid/squid.conf | grep -v ^# | grep -v ^$ > squiD.conf

Have fun!...
