Just work it out logically. What does bash do when you run 'bash filename'? How will it treat lines beginning with #?

NAME
dpkg-preconfigure - let packages ask questions prior to their installation SYNOPSIS
dpkg-preconfigure [options] package.deb dpkg-preconfigure --apt DESCRIPTION
dpkg-preconfigure lets packages ask questions before they are installed. It operates on a set of debian packages, and all packages that use debconf will have their config script run so they can examine the system and ask questions. OPTIONS
-ftype, --frontend=type Select the frontend to use. -pvalue, --priority=value Set the lowest priority of questions you are interested in. Any questions with a priority below the selected priority will be ignored and their default answers will be used. --terse Enables terse output mode. This affects only some frontends. --apt Run in apt mode. It will expect to read a set of package filenames from stdin, rather than getting them as parameters. Typically this is used to make apt run dpkg-preconfigure on all packages before they are installed. To do this, add something like this to /etc/apt/apt.conf: // Pre-configure all packages before // they are installed. DPkg::Pre-Install-Pkgs { "dpkg-preconfigure --apt --priority=low"; }; -h, --help Display usage help. SEE ALSO
