This was a Java applet

This exercise uses a Java applet to simulate a UNIX command line and allows you to practice entering commands. If you do not have Java active in your browser or are behind a firewall that does not allow Java applets, you will not be able to complete this exercise. If you do not see the applet below, click OK, I'm Done to view the exercise solution and continue with the course.

Background

You are the systems administrator for an organization with offices in Bombay, Seattle, and London. Currently, you are in Seattle. You have found that you must reboot one of your UNIX systems. You have learned that the shutdown -t1 -r command will reboot the system. This system is relatively new, and no one has used the shutdown command on it before.

Instructions

In this exercise, you will see how well you understand determining where a command is located and modifying the search path. Although the simulation uses a Linux machine, the process is almost identical across all versions. Start the simulation below and work through the situation presented.
