NAME
      ckbupscd - check file system backup schedule

SYNOPSIS
      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 bupsched file are printed under the control of cron.

      The file bupsched should contain lines of four or more fields, separated
      by spaces or tabs.  The first three 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), matching 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 the field in which
      it appears.

      A line beginning with a sharp sign (#) is interpreted as a comment and
      ignored.

      The longest line allowed (including continuations) is 1024 characters.

EXAMPLES
      The following are examples of lines which could appear in the
      /etc/bupsched file.
