SYNOPSIS¶
calendar |
[-ab -A
num-B
num-l
num-w
num-f
calendarfile-t
[[ ]dd[ ]mmcc ]yy |
DESCRIPTION¶
Thecalendar
utility checks the current
directory or the directory specified by the
CALENDAR_DIR
environment variable for a
file named calendar and displays lines that
begin with either today's date or tomorrow's. On Fridays, events on Friday
through Monday are displayed.
The options are as follows:
-A
num- Print lines from today and next num days (forward, future). Defaults to one. (same as -l)
-a
- Process the “calendar” files of all users and mail the results to them. This requires superuser privileges.
-B
num- Print lines from today and previous num days (backward, past).
-b
- Enforce special date calculation mode for KOI8 calendars.
-l
num- Print lines from today and next num days (forward, future). Defaults to one. (same as -A)
-w
num- Print lines from today and next num days,
only if today is Friday (forward, future). Defaults to two, which causes
calendar
to print entries through the weekend on Fridays. -f
calendarfile- Use calendarfile as the default calendar file.
-t
[[]dd[]mmcc]yy- Act like the specified value is “today” instead of using the current date. If yy is specified, but cc is not, a value for yy between 69 and 99 results in a cc value of 19. Otherwise, a cc value of 20 is used.
...
“+5” (aliases
last, first, second, third, fourth) for moving events like “the last
Monday in April”.
By convention, dates followed by an asterisk (‘*’) are not fixed,
i.e., change from year to year.
Day descriptions start after the first <tab> character in the line; if the
line does not contain a <tab> character, it isn't printed out. If the
first character in the line is a <tab> character, it is treated as the
continuation of the previous description.
The calendar file is preprocessed by cpp(1),
allowing the inclusion of shared files such as company holidays or meetings.
If the shared file is not referenced by a full pathname,
cpp(1) searches in the current (or home)
directory first, and then in the directory directory
/etc/calendar, and finally in
/usr/share/calendar. Empty lines and lines
protected by the C commenting syntax (/* ... */
) are
ignored.
Some possible calendar entries (a \t sequence denotes a <tab>
character):
LANG=C Easter=Ostern #include <calendar.usholiday> #include <calendar.birthday> 6/15\tJune 15 (if ambiguous, will default to month/day). Jun. 15\tJune 15. 15 June\tJune 15. Thursday\tEvery Thursday. June\tEvery June 1st. 15 *\t15th of every month. May Sun+2\tsecond Sunday in May (Muttertag) 04/SunLast\tlast Sunday in April, \tsummer time in Europe Easter\tEaster Ostern-2\tGood Friday (2 days before Easter) Paskha\tOrthodox Easter

SEE ALSO¶

Thecalendar
program previously selected
lines which had the correct date anywhere in the line. This is no longer true:
the date is only recognized when it occurs at the beginning of a line.
COMPATIBILITY¶
Thecalendar
command will only display lines
that use a <tab> character to separate the date and description, or that
begin with a <tab>. This is different than in previous releases.
The -t
flag argument syntax is from the
original FreeBSD calendar
program.
The -l
and
-w
flags are Debian-specific enhancements.
Also, the original calendar
program did not
accept 0
as an argument to the
-A
flag.
Using ‘utf-8’ as a locale name is a Debian-specific enhancement.
HISTORY¶
Acalendar
command appeared in
Version 7 AT&T UNIX.
