SLEEP(1)                   Commands and Applications                  SLEEP(1)




NAME

       sleep - suspend execution for an interval of time


SYNOPSIS

       sleep seconds


DESCRIPTION

       The  sleep  command suspends execution for a minimum of seconds.  sleep
       is used to schedule the  execution  of  other  commands  (see  EXAMPLES
       below).

       If  the sleep command receives a SIGALRM signal, it terminates normally
       with a zero exit status, for any other signal  it  takes  the  standard
       action.

       The sleep utility exits with one of the following values:

       0      On successful completion, or if the signal SIGALRM was received.

       >0     An error occurred.


EXAMPLES

       To schedule the execution of a  command  for  some  number  of  seconds
       later:

       sleep 1800; command_file

       This  incantation would wait a half hour before running the script com-
       mand_file. (See the at(1) utility.)
