How can I check installed program versions in terminal. Is there any command for that, for example ver or something similar?

@rusty That is clearly another question, even if the answer is there. –  Radu Rădeanu Mar 30 at 7:44

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.

package_name --version is not usually, it's a standard, so it must to work with any package. –  Radu Rădeanu Mar 30 at 7:30
    
package_name -v is also not usually. It works only for a small number of programs. See gedit -v, ls -l, chromium-browser -v, grep -v, sed -v, etc. So I think that is not a good advice at all. –  Radu Rădeanu Mar 30 at 7:42
    
Thanks @RaduRădeanu for correcting me. I meant to say application, but written package by mistake. Edited, plz check once. –  souravc Mar 30 at 7:58
    
@souravc It doesn't make any difference. See google-chrome -v or chromium-browser -v. And any application is a program for me. See also unix.stackexchange.com/q/2645/37944. –  Radu Rădeanu Mar 30 at 8:05
