→INVESTIGATION 2: MANAGING PROCESSES
# Issue the following Linux command: <span style="color:blue;font-family:courier;font-weight:bold">sleep 200</span><br><br>'''NOTE:''' The sleep command just waits for a specified number of seconds before completing<br>in order to return to the shell prompt. It is useful in order to force a pause in a sequence of commands.<br><br>
# Notice that this process will run for 200 seconds, and is forcing the user to wait until this process finishes.<br>A process that is running in the terminal is referred to as a '''foreground process'''.<br><br>The Unix/Linux system is designed to allow users to send preemptive signals to manage those processes.<br><br>
# Press the key combination: <span style="color:blue;font-family:courier;font-weight:bold"><ctrl><c></span><br><br>'''NOTE:''' The '''ctrl-c''' key combination sends '''SIGINT''' ('''Signal Interrupt''') to terminate a process that is running.
# After you complete the Review Questions sections to get additional practice, then work on your<br>online assignment 2 and complete section4 labelled: '''Linking files and directories'''.
