I have a script that is causing a bunch of ssh -D (socks proxy) connections to open. Sometimes one of them is trying to open on a port that is in use, in which case it prints an error. Unfortunately, after printing the error it does not terminate but rather keeps running. How can I tell SSH to terminate if it is unable to actually do what I'm asking it to do?
