My MacBook Air froze all of a sudden: the keyboard, trackpad and display are all unresponsive. However, ssh works.
I have one
tcsh session active. Which signal do I send to
tcsh for it to gracefully quit, saving history prior to quitting?
My tcsh does have all appropriate
savehist already setup, i.e. if I were to type in
exit, all history would be saved. Perhaps there is even some way for a superuser to steal the terminal, and actually pass in the characters
exit\n as if they were typed in on the virtual terminal by the logged-in user?
