If output scrolls up on your terminal screen faster than you can read it, you can suspend it by typing <ctrl-S>. To resume the display, type <ctrl-Q>. Again section [*] will discuss how to pass output through a paging program that will automatically display only one screen at a time. While I'm at it, <ctrl-C> will abort a process, and <ctrl-O> will discard the output until another <ctrl-O> is entered. Be sure to note that although the output doesn't appear, the process is still running. <ctrl-Z> suspends the current program. You can see its job number by typing jobs. You can resume the suspended program by giving the fg (foreground) command, or resume it in the background with bg.
