.SH DESCRIPTION
|
|
.PP
|
|
Basically \fIcalendar\fR program consults the file \fIcalendar\fR 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.
|
|
.PP
|
|
When an argument \fB\-\fR is present, \fIcalendar\fR works for all users
|
|
with a file \fIcalendar\fR in their login directories and sends them mail.
|
|
Normally this is done daily under the control of \fIcron\fR.
|
|
.PP
|
|
The \fB\-r\fR option does its the same job as \fB\-\fR option, but touches
|
|
the \fIcalendar\fR to prevents further access on the same day.
|
|
Normally this is done in the \fI/etc/rc\fR file on a machine which may be
|
|
booted several times in one day.
|
