How to tell which version of software you're running

How can you tell which version of something you're running?
Like, I need to know which version of exim I'm running, which version of Perl, which version of SpamAssassin, etc.

Is there a general command that does this? I can (sometimes) find src files and look that way (SpamAssassin-2.63.tar.gz, for example). Is there a more sophisticated way?

Code:

bash -v
vim -v
apache -v

If you have a distribution that supports package managers (and if the package you're interested in happens to have been installed with that manager, instead of manually) then that's your best bet.

For example, on SuSE Linux, I would go into "YaST2, Control Panel", select "Install/Remove Software", and choose "Search" to query any package.

Otherwise, most packages (Perl, for instance), support a "-v" command line switch.

Hope that helps .. PSM
