ckbupscd(1M)                                                   ckbupscd(1M)


   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.
