I'm new to Ubuntu. I would like to know how to locate a certain software application and remove it.
Here's how to do it on the command line:
Open up your terminal, and run
dpgk -l | grep $APPNAME, where `$APPNAME' is the name of the application you are looking for. This searches all of the packages installed on your computer.
The package names are listed in the second column. Pick the one you want to remove, then run
sudo apt-get remove $PACKAGE_NAME, with the appropriate name substituted to remove the application.
