# Issue the following Linux command: <span style="color:blue;font-family:courier;font-weight:bold">bg</span><br><br>'''NOTE:''' You can use the bg command WITHOUT arguments to specify the most recent process<br>that was placed into the background. From the '''jobs''' command, the process that has a plus sign "+"<br>indicates the most recent process placed into the background.<br><br>
# Issue the following Linux command: <span style="color:blue;font-family:courier;font-weight:bold">jobs</span><br><br>You should see the following output similar that was displayed above:<br><span style="font-family:courier;font-weight:bold">[1]+ sleep 700 &</span><br><br>This display indicates that this process in the background is '''running in the background'''<br>(denoted by the ampersand character "&"). Now the command is counting-down to zero.<br><br>
# Issue the following Linux command: <span style="color:blue;font-family:courier;font-weight:bold">fg</span><br><br>You should notice that the ''sleep'' command is now running in the '''foreground'''.<br><br>You can run issue Linux commands with ampersand "'''&'''" in your terminal to '''run ''' processes in the '''background''' automatically <u>without</u> having to issue ''ctrl-z'' and ''bg'' short-cut keys.<br><br>
# Press the key combination: <span style="color:blue;font-family:courier;font-weight:bold">ctrl-c</span> to '''terminate''' the process running in the foreground.<br><br>
