double mailings from calendar(1)

[era at niwot.ucar.edu]

A while back, I inquired as to whether anyone else had received double
mailings from the calendar(1) program running under 4.0.  As soon as a
sun-spots reader reminded me that /usr/bin/calendar is a shell script, the
source of the problem was obvious.

If you have a server running YP, then /usr/bin/calendar is double-counting
everyone by concatenating YP passwd.byname and /etc/passwd.  You can get
rid of the double mailings by making this change:

27c27
< 	$caldata |cat /etc/passwd - | grep -v '^[+-]' |\
---
> 	$caldata |cat /etc/passwd - | grep -v '^[+-]' | sort | uniq | \
