# Press the '''key combination''' to '''terminate''' the process running in the '''foreground''': <span style="color:blue;font-family:courier;font-weight:bold">ctrl-c</span> <br><br>You can issue Linux commands with ampersand "'''&'''" in your terminal to '''run''' processes automatically in the<br>'''background''' <u>without</u> having to issue ''ctrl-z'' and ''bg'' short-cut keys.<br><br>

# Issue the '''jobs''' command. What do you notice?<br><br>In the jobs command output, jobs that display a plus sign ('''+''') indicates the '''most recent''' process<br>placed in to the background, and a minus sign ('''-''') indicates the '''second most recent''' process<br>placed into the background.<br><br>The '''kill''' command issued to terminate processes that are running in the '''foreground''' or '''background'''.<br>Issuing the kill command <u>without</u> options would send the '''SIGTERM''' signal (eg. ''signal terminate'' - which is signal '''#15''').<br><br>
