Remove Comments from Configuration

If you want to configure something, sometimes it contains the comments from the developer which help us to figure out options of arguments that will be used. But if you are already familiar with the configuration, comments can be annoying, and here we provide a way to remove them (using apache2.conf as example):

sed '1p; /^[[:blank:]]*#/d; s/[[:blank:]][[:blank:]]*#.*//' /etc/apache2/apache2.conf | more

or write it to a file:

sed '1p; /^[[:blank:]]*#/d; s/[[:blank:]][[:blank:]]*#.*//' /etc/apache2/apache2.conf > /etc/apache2/apache2.conf.nocomments

Use it with caution, always review it. You’ve been warned!
