DESCRIPTION
|
|
|
|
Basically calendar program consults the file calendar in the current
|
|
directory and display lines which contain today's or tomorrow's date.
|
|
Month-day formats such as '12/25', 'Dec. 25', 'december 25', '*/25',
|
|
'12/*', '*/*' are recognized. The asterisk means 'all' days or 'all'
|
|
months. On weekends 'tomorrow' extends through next Monday without any
|
|
consideration about holidays. To prevent ambiguity, the formats '25
|
|
Dec.' and '25/12' are not recognized.
|
|
|
|
When an argument - is present, calendar works for all users with a file
|
|
calendar in their login directories and sends them mail. Normally this
|
|
is done daily under the control of cron.
|
|
|
|
The -r option does its the same job as - option, but touches the calendar
|
|
to prevents further access on the same day. Normally this is done in the
|
|
/etc/rc file on a machine which may be booted several times in one day.
