Ubuntu Linux: How Do I install .deb Packages?

Posted on in Categories , , last updated August 11, 2013

I am a new Ubuntu Linux user. I need to install a package called package.deb. I know I can use Synaptic front-end package management tool to install packages from the CD or Internet. But, I would like to install a special .deb file. How can I install .deb package from the terminal using command line option in Ubuntu Linux or Debian Linux?
