In a graphical environment, the xkill program is very easy to use. Just type the name of the command, followed by an Enter and select the window of the application that you want to stop. It is rather dangerous because it sends a SIGKILL by default, so only use it when an application hangs.

4.4.1. Use that idle time!
A Linux system can have a lot to suffer from, but it usually suffers only during office hours. Whether in an office environment, a server room or at home, most Linux systems are just idling away during the morning, the evening, the nights and weekends. Using this idle time can be a lot cheaper than buying those machines you'd absolutely need if you want everything done at the same time.
There are three types of delayed execution:
• Waiting a little while and then resuming job execution, using the sleep command. Execution time depends on the system time at the moment of submission.
• Running a command at a specified time, using the at command. Execution of the job(s) depends on system time, not the time of submission.
