I have a problem with my environment variables(I kind of messed up the path and I need the standard variable). I don't know where to ask this question. I was thinking about Super User but I wasn't sure. Where should I ask this question?
In most cases Super User is the place to ask. There are also sites specifically for Unix & Linux, Ubuntu, and Apple questions, so you might try one of those if they apply. If it's an environment variable specifically for a programming tool (e.g., JAVA_HOME) you should be able to ask on Stack Overflow.
