I want to write a script that "links" an emacs server to a certain directory.
To do so I need to check all existing servers to be sure if a server with a specific name is running or not. Then the script can decide to start a new server, or not, before opening a file from that directory using emacsclient.

I have been looking around to find out how to list the existing emacs running servers, unsuccessfully though.

Is there anything like `emacs --list-servers` that I could use?

Cheers.
