Newsgroups: comp.sources.misc From: allbery@uunet.UU.NET (Brandon S. Allbery - comp.sources.misc) Subject: v06i099: Happy birthday to you... Reply-To: rsalz@bbn.com (Rich Salz) Posting-number: Volume 6, Issue 99 Submitted-by: rsalz@bbn.com (Rich Salz) Archive-name: bday There used to be a machine called oz.ai.mit.edu, and it used to have a wizard who knew when it was your birthday. He was a friendly wizard, not at all deserving of the name "daemon," because he'd send you a nice little note when that special day came around... I had been saving one of my messages for some time, but only just now got around to writing this program. It reads a file with email names and birthdays, and sends mail. It should be run out of cron early every morning. If WEEKEND_HACK is #define'd, then on Friday bday will send mail to people with birthdays on Saturday and Sunday. The program uses getopt and sendmail, but hacking around the latter should be pretty easy. /rich $alz #! /bin/sh # This is a shell archive.

XIt reads a file containing a list of user names and birthdays, Xand sends a message to anyone whose birthday is today. XThe ``\-r'' option may be used to specify a person who should receive Xa report whenever a greeting is sent. X.PP XThe ``\-b'' option may be used to specify the file containing the list Xof people's birthdays; the default is X.IR /usr/adm/bdaylist . XThis file should consist of a series of lines of three fields, each separated Xby whitespace: X.RS X.nf X.ta \w'#emailname 'u +\w'month 'u X#emailname month day Xrsalz 2 10 X.fi X.RE XThe first column is the name of the person to send the email message to. XThe second column is the month in which the person's birthday occurs; X1 is for January, and so on up to 12 for December. XThe third column is the day of the month on which their birthday occurs. XBlank lines, and any text after a pound sign is ignored. X.PP XThe ``\-m'' option may be used to specify the file with the birthday message; Xthe default is X.IR /usr/adm/bdaymesg . XThis is useful, for example, to send different greetings to people who's Xbirthday falls on a weekend. X.PP XThe command used to send the mail may be changed by giving the ``\-s'' Xoption; this is useful for debugging. XNote that the details of sending the message (such as the mail headers) Xare compiled into the code, but that's okay because this is just a short Xfun hack, anyhow.
