A terminal emulator is an application whose window provides a command line. The command line lets you type commands into your system--for example, operating system commands, script names, or commands that run applications.
All applications have a command that users can type to start them. The application's documentation usually describes how to use the command.
The desktop provides a terminal emulator called dtterm. Your system may include other terminal emulators.
To open a terminal emulator window, click the Terminal control in the Personal Applications subpanel.
For more information on using dtterm, see Chapter 12, Using Terminal .
Type the command that starts the application into the terminal emulator window.
If the application has its own window, you should add an ampersand character (&) to the end of the command. This runs the application ``in the background,'' which lets you continue using the terminal emulator window while the application is running.
For example, the following command runs the load meter program xload in the background:
/usr/bin/X11/xload &
There are two ways to use a command line to start an application on another system:
Using rlogin
Using remsh
When you use rlogin, you use your terminal emulator to log in to a different (remote) system. You then run the command to start the application on that system.
Use the rlogin command to log in to the system containing the application.
rlogin remote_system_name
For example:
rlogin systemA
Type the command to start the application. Use the -display option to send the window back to your display.
For example, assuming your own system's display name is MySystem:0:
/usr/bin/X11/xload -label systemA -display MySystem:0
The term remsh stands for "remote shell." It provides a one-step way to run an application, since you do not have to log in before running the command.
Type the command:
remsh remote_system_name -n command
The command must include the -display option to send the window back to your display.
For example:
remsh systemA -n /usr/bin/X11/xload -display MySystem:0
