Automatically flush PF_UNIX sockets when exiting a process?

Can I clear UNIX domain sockets automatically when the process that created them is complete?

If your application needs to be run only on Linux, you can use an abstract unix socket (a socket where the path starts with a NULL byte). Abstract sockets are automatically cleared when the server process completes.

Either by fixing the application so that it deletes (disconnects) the socket file on exit, or if you know the location of the socket file:

fuser sockfile.sock || rm sockfile.sock

This checks if the process uses the file and if it does rm if it does not. You can put this in a shell script that actually executes the application and subsequently flushes the socket file.
