You can create a Shell tool in one of two ways:
Meta+X Shellin any Editor window (or any other window based on an editor, such as the Listener).
Figure 23.1 The Shell tool
The Operations menu contains the following commands which send UNIX signals to the shell process. These only work on UNIX and UNIX-based systems, including Mac OS X.
Choose Operations > Interrupt to send a break signal to the shell process. This stops the current task and returns control to the UNIX command line in the Shell tool, if necessary.
Operations > Suspend
to send a suspend signal to the shell process. This suspends the current task so that you can continue entering commands at the UNIX command line. To resume the task, type
at the UNIX command line in the Shell tool. Alternatively, type
at the command line to force a task to run in the background.
Choose Operations > Eof to send an EOF signal to the process.
