How can I check installed program versions in terminal. Is there any command for that, for example ver or something similar?
01 Answer
The way how to know version of an installed package varies for different programs. Usually
application_name --versionor
application_name -versioncan 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_nameIn 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.
