Uninstall Linux ApplicationsΒΆ

Usually it is pretty simple to uninstall an application, using GUI tools like software managers. Sometimes some apps do not show up in GUI and hence we need to use Terminal to remove those applications. While the command to remove the application is simple, the exact name of the program needs to be known inorder to execute the command. 

apt-cache search ProgramName
Where, ProgramName is the partial or complete name of the program thats needs to be uninstalled. As an example, the following command will search for the program okular 
apt-cache search okular
Once the correct name is known, simply issue the following command 
sudo apt purge ProgramName
or, 
sudo apt remove ProgramName
The Purge and Remove is that purge command removes the configuration files of the related program as well.
