Without knowing what your hibernate.sh script does, it's quite difficult to advise you on how to improve it. Also bear in mind, I'm probably not the best person to give advice on laptop-specific issues such as hibernation. I don't use a Linux laptop, and I've never hibernated a system in my life. Generally speaking, though -- if your ssh client is hanging, it's because some process with stdout and/or stderr opened to the ssh client is still running. That *one* process might need to have its output redirected. The rest of the script can be left alone. If that single process is the one that's causing the laptop to hibernate, and doesn't end until the laptop is re-awakened, then you won't know whether it "executed successfully" until the laptop is re-awakened. Not seeing that process's exit status seems acceptable. It's also conceivable that you're using the wrong command(s) to invoke the hibernation. That part is 100% outside my experience, though.
