Best Answer

The way how to know version of an installed package varies for different programs. Usually

application_name --version

or

application_name -version

can be used to know it. It is better to see man application_name and search which is the command line switch to know the version.

If you installed any package using apt, to see the version you can try

apt-cache policy package_name

In few cases the version can be found in application_name --help. For example virtualbox

In few very little case application_name -v also gives you version.
