Removing Comments and Blank lines of a config file

Template:AdWords Using 'grep' and 'sed' we can strip out comments and blank lines of any file. you can then redirect the output to a file if you so wish. In this example I will use it to remove the comments and blank lines from my apache2.conf file

grep -v "#" /etc/apache2/apache2.conf | sed -e '/^$/d'

If you wish to leave the blank lines then simply omit the sed statement.
