calendar
CALENDAR(1) General Commands Manual CALENDAR(1) NAME
calendar - reminder service SYNOPSIS
calendar [ - ] 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'. 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 posi- tive results by mail(1). Normally this is done daily in the wee hours under control of cron(8). FILES
calendar /usr/lib/calendar to figure out today's and tomorrow's dates /etc/passwd /tmp/cal* egrep, sed, mail subprocesses SEE ALSO
at(1), cron(8), mail(1) BUGS
Your calendar must be public information for you to get reminder service. Calendar's extended idea of `tomorrow' doesn't account for holidays. CALENDAR(1)
