Shell Program For Mac
Terminating Programs To terminate the currently running program from the command line, press Control-C. This keyboard shortcut sends an abort ( ABRT) signal to the currently running process. In most cases this causes the process to terminate, although some tools may install signal handlers to trap this signal and respond differently. (See in for details.) In addition, you can terminate most scripts and command-line tools by closing a Terminal window or SSH connection. This sends a hangup ( HUP) signal to the shell, which it then passes on to the currently running program. If you want a program to continue running after you log out, you should run it using the nohup command, which catches that signal and does not pass it on to whatever command it invokes.
