Hey all, I am new to Rails so sorry if this is such an elementary  
question…

From a command line, how can I list out all of my currently installed  
gems and their version numbers? I am pretty sure that I have a few  
that need to updated to the latest versions, but I am unsure of how to  
know which versions that I currently have installed!

Thanks!

Wow, who have thought it was that easy? I think I tried every  
combination except that one!

Thanks Bill.

Then maybe you should also try this one:

gem help commands
