__DESCRIPTION__ |
|
|
15 |
|
|
|
16 |
|
|
|
17 |
Calendar checks the current directory for a file named |
|
|
18 |
calendar and displays lines that begin with either |
|
|
19 |
today's date or tomorrow's. On Fridays, events on Friday |
|
|
20 |
through Monday are displayed. If there is no configuration |
|
|
21 |
file in the current directory, /etc/calendar/default is used |
|
|
22 |
(if present). |
|
|
23 |
|
|
|
24 |
|
|
|
25 |
The following options are available: |
|
|
26 |
-a Process the ``calendar'' files of all users and mailthe results to them. This requires super-user privi-leges. |
|
|
27 |
|
|
|
28 |
|
|
|
29 |
-A numPrint lines from today and the next num days (for-ward, future).-B numPrint lines from today and the previous num days(backward, past).-f calendarfileUse calendarfile as the default calendar file. |

-t |
|
|
33 |
dd[[.mm[[.year]] |
|
|
34 |
For test purposes only: set date directly to argument |
|
|
35 |
values. |
|
|
36 |
|
|
|
37 |
|
|
|
38 |
-l days |
|
|
39 |
Causes the program to ``look ahead'' a given number of days |
|
|
40 |
(default one) from the specified date and display their |
|
|
41 |
entries as well. |
|
|
42 |
|
|
|
43 |
|
|
|
44 |
-w days |
|
|
45 |
Causes the program to add the specified number of days to |
|
|
46 |
the ``look ahead'' number if and only if the day specified |
|
|
47 |
is a Friday. The default value is two, which causes calendar |
|
|
48 |
to print entries through the weekend on |
|
|
49 |
Fridays. |
|
|
50 |
|
|
|
51 |
|
|
|
52 |
To handle calendars in your national code table you can |
|
|
53 |
specify ``LANG= |
|
|
54 |
|
|
|
55 |
|
|
|
56 |
Other lines should begin with a month and day. They may be |
|
|
57 |
entered in almost any format, either numeric or as character |
|
|
58 |
strings. If the proper locale is set, national month and |
|
|
59 |
weekday names can be used. A single asterisk (``'') matches |
|
|
60 |
every month. A day without a month matches that day of every |
|
|
61 |
week. A month without a day matches the first of that month. |
|
|
62 |
Two numbers default to the month followed by the day. Lines |
|
|
63 |
with leading tabs default to the last entered date, allowing |
|
|
64 |
multiple line specifications for a single date. |
|
|
65 |
|
|
|
66 |
|
|
|
67 |
``Easter'', is Easter for this year, and may be followed by |
|
|
68 |
a positive or negative integer. |
|
|
69 |
|
|
|
70 |
|
|
|
71 |
``Paskha'', is Orthodox Easter for this year, and may be |
|
|
72 |
followed by a positive or negative integer. |
|
|
73 |
|
|
|
74 |
|
|
|
75 |
Weekdays may be followed by ``-4'' ... ``+5'' (aliases for |
|
|
76 |
last, first, second, third, fourth) for moving events like |
|
|
77 |
``the last Monday in April'' |
|
|
78 |
|
|
|
79 |
|
|
|
80 |
By convention, dates followed by an asterisk are not fixed, |
|
|
81 |
i.e., change from year to year. |
|
|
82 |
|
|
|
83 |
|
|
|
84 |
Day descriptions start after the first |
|
|
85 |
|
|
|
86 |
|
|
|
87 |
The ``calendar'' file is preprocessed by cpp(1), |
|
|
88 |
allowing the inclusion of shared files such as lists of |
|
|
89 |
company holi- days or meetings. If the shared file is not |
|
|
90 |
referenced by a full pathname, cpp(1) searches in |
|
|
91 |
the current (or home) directory first, and then in the |
|
|
92 |
directory /etc/calendar/, then in |
|
|
93 |
/etc/calendar, then in |
|
|
94 |
/usr/share/calendar/ and finally in |
|
|
95 |
/usr/share/calendar. Empty lines and lines |
|
|
96 |
protected by the C commenting syntax (/ ... /) are |
|
|
97 |
ignored. |

The calendar program previously selected lines which had the |
|
|
201 |
correct date anywhere in the line. This is no longer true, |
|
|
202 |
the date is only recognized when it occurs at the beginning |
|
|
203 |
of a line. |

Having a directory per year is a Debian-specific improvement over the standard BSD calendar. |
|
|
207 |
|
|
|
208 |
|
|
|
209 |
Older calendar releases distributed with Debian supported |
|
|
210 |
the -t option which has been superseded by the -A and -B |
|
|
211 |
options and the ~/.calendar file which has been |
|
|
212 |
superseded by the ~/.calendar |
|
|
213 |
directory. |

__HISTORY__ |

__BUGS__ |
|
|
220 |
|
|
|
221 |
|
|
|
222 |
Calendar doesn't handle Jewish holidays and moon phases. The |
|
|
223 |
-A and -l options do very similar things. |
