sleep(1)                         DG/UX R4.11                        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.
