.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility checks the current directory for a file named
|
|
.Pa calendar
|
|
and displays lines that begin with either today's date
|
|
or tomorrow's.
|
|
On the day before a weekend (normally Friday), events for the next
|
|
three days are displayed.
|
|
.Pp
|
|
The following options are available:
|
|
.Bl -tag -width Ds
|
|
.It Fl A Ar num
|
|
Print lines from today and the next
|
|
.Ar num
|
|
days (forward, future).
|
|
.It Fl a
|
|
Process the ``calendar'' files of all users and mail the results
|
|
to them.
|
|
This requires super-user privileges.
|
|
.It Fl B Ar num
|
|
Print lines from today and the previous
|
|
.Ar num
|
|
days (backward, past).
|
|
.It Fl F Ar friday
|
|
Specify which day of the week is ``Friday'' (the day before the
|
|
weekend begins).
|
|
Default is 5.
|
|
.It Fl f Pa calendarfile
|
|
Use
|
|
.Pa calendarfile
|
|
as the default calendar file.
|
|
.It Xo Fl t

|

|

|
For test purposes only: set date directly to argument values.
|
|
.It Fl W Ar num
|
|
Print lines from today and the next
|
|
.Ar num
|
|
days (forward, future).
|
|
Ignore weekends when calculating the number of days.
|
|
.El
|
|
.Pp
|
|
To handle calendars in your national code table you can specify
|
|
.Dq LANG=<locale_name>
|
|
in the calendar file as early as possible.
|
|
To handle national Easter
|
|
names in the calendars
|
|
.Dq Easter=<national_name>
|
|
(for Catholic Easter) or
|
|
.Dq Paskha=<national_name>
|
|
(for Orthodox Easter) can be used.
|
|
.Pp
|
|
Other lines should begin with a month and day.
|
|
They may be entered in almost any format, either numeric or as character
|
|
strings.
|
|
If the proper locale is set, national month and weekday
|
|
names can be used.
|
|
A single asterisk (``*'') matches every month.
|
|
A day without a month matches that day of every week.
|
|
A month without a day matches the first of that month.
|
|
Two numbers default to the month followed by the day.
|
|
Lines with leading tabs default to the last entered date, allowing
|
|
multiple line specifications for a single date.
|
|
.Pp
|
|
``Easter'', is Easter for this year, and may be followed by a positive
|
|
or negative integer.
|
|
.Pp
|
|
``Paskha'', is Orthodox Easter for this year, and may be followed by a
|
|
positive or negative integer.
|
|
.Pp
|
|
Weekdays may be followed by ``-4'' ...\& ``+5'' (aliases for
|
|
last, first, second, third, fourth) for moving events like
|
|
``the last Monday in April''.
|
|
.Pp
|
|
By convention, dates followed by an asterisk are not fixed, i.e., change
|
|
from year to year.
|
|
.Pp
|
|
Day descriptions start after the first <tab> character in the line;
|
|
if the line does not contain a <tab> character, it is not displayed.
|
|
If the first character in the line is a <tab> character, it is treated as
|
|
a continuation of the previous line.
|
|
.Pp
|
|
The ``calendar'' file is preprocessed by
|
|
.Xr cpp 1 ,
|
|
allowing the inclusion of shared files such as lists of company holidays or
|
|
meetings.
|
|
If the shared file is not referenced by a full pathname,
|
|
.Xr cpp 1
|
|
searches in the current (or home) directory first, and then in the
|
|
directory
|
|
.Pa /usr/share/calendar .
|
|
Empty lines and lines protected by the C commenting syntax
|
|
.Pq Li /* ... */
|
|
are ignored.
|
