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 sys-
     tems 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  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.

     06:00-09:00  fri  1,2,3,4,5,6,7,8,9,10,11  /applic
             Prints the file system name /applic if  ckbupscd  is
             run  between  6:00  A.M.  and  9:00 A.M.  any Friday
