NAME
     ckbupscd - check file system backup schedule

SYNOPSIS
     /etc/ckbupscd [ -m ]

DESCRIPTION
     ckbupscd consults the file /etc/bupsched and prints the file
     system lists from lines with date and time specifications
     matching the current time.  If the -m flag is present an
     introductory message in the output is suppressed so that
     only the file system lists are printed. Entries in the
     /etc/bupsched file are printed under the control of cron.

     The System Administration commands bupsched/schedcheck are
     provided to review and edit the /etc/bupsched file.

     The file /etc/bupsched should contain lines of 4 or more
     fields, separated by spaces or tabs.  The first 3 fields
     (the schedule fields) specify a range of dates and times.
     The rest of the fields constitute a list of names of file
     systems to be printed if ckbupscd is run at some time within
     the range given by the schedule fields.  The general format
     is:

          time[,time] day[,day] month[,month] fsyslist

     where:

     time    Specifies an hour of the day (0 through 23), match-
             ing any time within that hour, or an exact time of
             day (0:00 through 23:59).

     day     Specifies a day of the week (sun through sat) or day
             of the month (1 through 31).

     month   Specifies the month in which the time and day fields
             are valid.  Legal values are the month numbers (1
             through 12).

     fsyslist
             The rest of the line is taken to be a file system
             list to print.

     Multiple time, day, and month specifications may be
     separated by commas, in which case they are evaluated left
     to right.

     An asterisk (*) always matches the current value for that
     field.
