Telling which ruby on rails project is running

Question

My client wants me to download a working ruby on rails project to my local system. But when I connected to a server, I got nine identical project folders (which seem like different versions). Is there a way to know which project is running using process id (I have only the process id)?

Answer 1

If you have the process ID, then check /proc/[pid]/cwd symbolic link. This is the process' current directory.

I assume that you are on a Linux-like system.

If you are not, then you may issue a HTTP request (to wake up the rails app) and then look which logfile has been modified recently.
