NAME
ckbupscd - Checks file system backup schedule
SYNOPSIS
/etc/ckbupscd [-m]
FLAGS
-m Suppresses an introductory message in the output so that only the
file system lists are displayed.
DESCRIPTION
The ckbupscd command consults the file /etc/bupsched and displays the file
system lists from lines with date and time specifications matching the
current time. Entries in the /etc/bupsched file are displayed 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 displayed 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
display.
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.
A line beginning with a pound sign (#) is interpreted as a comment and
