CALENDAR(1)CALENDAR(1)NAMEcalendar - reminder service
SYNOPSIScalendar [ - ]
DESCRIPTION
Calendar consults the file `calendar' in the current directory and
prints out lines that contain today's or tomorrow's date anywhere in
the line. Most reasonable month-day dates such as `Dec. 7,' `december
7,' `12/7,' etc., are recognized, but not `7 December' or `7/12'. If
you give the month as ``*'' with a date, i.e. ``* 1'', that day in any
month will do. On weekends `tomorrow' extends through Monday.
When an argument is present, calendar does its job for every user who
has a file `calendar' in his login directory and sends him any positive
results by mail(1). Normally this is done daily in the wee hours under
control of cron(8).
The file `calendar' is first run through the ``C'' preprocessor,
/lib/cpp, to include any other calendar files specified with the usual
``#include'' syntax. Included calendars will usually be shared by all
users, maintained and documented by the local administration.
