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

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. Mar 30 '14 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. Mar 30 '14 at 7:42
  • Thanks @RaduRădeanu for correcting me. I meant to say application, but written package by mistake. Edited, plz check once.

  • @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. Mar 30 '14 at 8:05
