sleep(1)                   DG/UX 4.30                    sleep(1)



     NAME
          sleep - suspend execution for an interval

     SYNOPSIS
          sleep time

     DESCRIPTION
          Sleep suspends execution for time seconds.  You can use it
          to execute a command after a certain amount of time, as in:

               (sleep 105; command)&

          or to execute a command every so often, as in:

               while true
               do
                    command
                    sleep 37
               done


     EXAMPLES
          $ sleep 60; date

          Waits about 60 seconds, then executes the date(1) command.
          Using this format of the command, your current shell waits.

          $ ( sleep 60; date )&

          Waits about 60 seconds, then executes the date(1) command.
          This format of the command starts a background shell and
          allows your current shell to continue.  For most
          applications of sleep this is probably prefered.

          $ while true; do ps -a; sleep 10; done &

          Executes the ps command approximately every 10 seconds.
          Prints information about all processes associated with the
          terminal except for process group leaders.
