What directory do I install new programs
As you can guess by the subject line I am pretty new to Linux. I have played around with installing different distros and have used the programs that come with those distros for a couple months. However, I would like to know what is the most common directory to install programs in. I know that it doesn't really matter, at least I don't think it does, but I was wanting to know what the general rule is.
Also, I frequently upgrade to new distros, so I would like to install them in a place that will not get overwritten when I upgrade. Finally, I want it to be accessible to all users on the system.
I hope that someone can help enlighten me in my quest for Linux knowledge!
