	  crontab -l

	  Level:    HP-UX/STANDARD

	  Origin:   System V

     DESCRIPTION
	  Crontab copies the specified file, or standard input if no
	  file is specified, into a directory that holds all users'
	  crontabs.  The -r option removes a user's crontab from the
	  crontab directory.  Crontab -l will list the crontab file
	  for the invoking user.

	  A user is permitted to use crontab if their name appears in
	  the file /usr/lib/cron/cron.allow. If that file does not
	  exist, the file /usr/lib/cron/cron.deny is checked to
	  determine if the user should be denied access to crontab. If
	  neither file exists, only root is allowed to submit a job.
	  If either file is at.deny, global usage is permitted.	 The
	  allow/deny files consist of one user name per line.

	  A crontab file consists of lines of six fields each.	The
	  fields are separated by spaces or tabs.  The first five are
	  integer patterns that specify the following:

	       minute (0-59),
	       hour (0-23),
	       day of the month (1-31),
	       month of the year (1-12),
	       day of the week (0-6 with 0=Sunday).

	  Each of these patterns may be either an asterisk  (meaning
	  all legal values), or a list of elements separated by
	  commas.  An element is either a number, or two numbers
	  separated by a minus sign (meaning an inclusive range).
	  Note that the specification of days may be made by two
	  fields (day of the month and day of the week).  If both are
	  specified as a list of elements, both are adhered to.	 For
	  example, 0 0 1,15 * 1 would run a command on the first and
	  fifteenth of each month, as well as on every Monday.	To
	  specify days by only one field, the other field should be
	  set to * (for example, 0 0 * * 1 would run a command only on
	  Mondays).

	  The sixth field of a line in a crontab file is a string that
	  is executed by the shell at the specified times.  A percent
	  character in this field (unless escaped by \) is translated
	  to a new-line character.  Only the first line (up to a % or
	  end of line) of the command field is executed by the shell.
	  The other lines are made available to the command as
	  standard input.

	  The shell is invoked from your $HOME directory with an arg0
	  of sh.  Users who desire to have their .profile executed
	  must explicitly do so in the crontab file.  Cron supplies a
	  default environment for every shell, defining HOME, LOGNAME,
	  SHELL(=/bin/sh), and PATH(=:/bin:/usr/bin:/usr/lbin).

	  NOTE: Users should remember to redirect the standard output
	  and standard error of their commands!	 If this is not done,
	  any generated output or errors will be mailed to the user.
