After using APT (Advanced package management tool), it is generally not necessary to process a single deb file. If necessary, use the dpkg command.

Loading gedit:

# dpkg-i Gedit-2.12.1.deb

Unloading:

# Dpkg-r Gedit

Just write a name here. You can also add the--purge (-p) flag:

# dpkg-p Gedit

This will be removed along with the Gedit configuration file, with-R only if the configuration file is not deleted.

If you don't want to install a deb package, but want to see what files it contains:

# dpkg-c Gedit-2.12.1.deb

If you want more information:

# dpkg-i Gedit-2.12.1.deb

You can also use wildcard characters to list the software on your machine:

# dpkg-l gcc*

This will list all the packages that begin with GCC

If you want to see if a package is already installed:

# dpkg-s Gedit

If you want to see what files a software has, where it is installed:

# dpkg-l Gedit

If you want to see only some of these files, add grep:

# dpkg-l gedit grep png
