Software Installation steps UBUNTU

HOW TO LIST INSTALLED SOFTWARES

The apt tool on Ubuntu 14.04 and above makes this very easy.

apt list --installed

Older Versions

To get a list of packages installed locally do this in your terminal:

dpkg --get-selections | grep -v deinstall

(The -v tag "inverts" grep to return non-matching lines)

To get a list of a specific package installed:

dpkg --get-selections | grep postgres

To save that list to a text file called packages on your desktop do this in your terminal:

dpkg --get-selections | grep -v deinstall > ~/Desktop/packages

Alternatively, simply use

dpkg -l

List installed hardware drivers.

lshw -html > system.html && xdg-open ./system.html

List modules being used

lsmod
