Hi saief,

Welcome to LQ!!!

Small tip before we start with your query. Title of your post does not state that what exactly you are looking for. Putting titles like this might not get the proper attention. I would suggest you to look at the following link and make yourself aware how you can make your post more effective: http://www.linuxquestions.org/linux/...Ask_a_Question

Coming back to your query. It is quite a simple query and you would got the answer by searching on google which you didn't. We are here to help you but if you are not ready to take effort then we can't help.

How to find the package version will depend on which distribution you are using. If you are using a distribution which is deb based like Ubuntu and Debian you can run the following command to get the version information.

If you are using rpm based distribution then you can run the following command to get the version information:

the current version for your operating system

It also helps to clarify your questions with a few details. Do you need the version info for individual programs, the distribution, the distribution's packages, or even a single specific program? What do you need this info for? scripting? Or just personal edification?

In any case, this kind of thing is generally trivial to find with just a tiny bit of effort. In addition to the above advice, almost every individual program includes some way to display its own current version information.

For gui programs you usually just look in the "help/about" menu or similar.

cli programs (and gui programs launched from the shell) generally have an option like -v or --version or similar. You can usually find a list of options by reading the man page ("man programname") or using quick help info option (generally something like "programname --help").
