Sorry that I missed the original post by Hamish.

I recently posted this script in alt.sources and sent it to the
figlet list.  It seems that it would be appropriate to post it
here too...

This Bourne shell script "injects" sigs and "fortune cookies" into
your email and usenet posts on a (pseudo) random basis.

I've tested this quite extensively, but I CANNOT guarantee that
it will work perfectly for you.  Read the notes at the end of
this script about how to use it and how to set up mail/mailx and
nn to enable this.  Note that I have only ever used this with these
programs... I have no idea how they might work with other email
program and news readers like pine, rn, or tin.

Be sure to read this script throughly, making alterations where
necessary for your system / setup.  It should be fairly generic
as it is, once you have things set up for yourself.  Check also
your man pages for nn, mail, mailx and sendmail to make sure they
will behave as expected.  Experiment by emailing to yourself, and
posting in misc.test or alt.test.

It works for me.  Your mileage may vary.  If anyone picks up any
bugs or has suggestions for improvements, then please don't
hesitate to email me.  I have thought of some improvements, which
I'll eventually get around to doing.

injector is shar'ed below.

Oh, one last thing.  I've included another little script that I
use to centre lines.  I use it in my injector script.  I'll put
this one here plain... if anyone can suggest how I can improve on
this one, I'm all ears!  (It uses nawk, but surely there's a
better way to do it:)  This script follows the shar script.

Enjoy!

X#
X# WARNING!       USE AT YOUR OWN RISK !!!
X#
X# You are well advised to test this script before using it by
X# emailing to yourself and posting to misc.test or alt.test
X# (with "ignore no reply" as the subject, unless you like lots
X# of dead email :-).
X#
X# Read the man pages for nn, mail, mailx and sendmail
X# (and inews if it's there) before using this script.

X################################################################
X#
X#           SETUP AND USAGE NOTES
X#
X# This file works by taking a message being piped to it from
X#   mailx and nn, WITH command-line parameters.
X#
X###############################
X#
X# To use this script with mail or mailx, point the
X#    sendmail variable in the ~/.mailrc file to it:
X#
X# sendmail=/<fullpath>/injector
X#
X###############################
X#
X# To use with nn, add the following to the ~/.nn/init file
X#    to point the inews and mailer variables to it:
X#
X# set inews /<fullpath>/injector -N -h
X# set mailer /<fullpath>/injector -t
X# set append-signature-mail false
X# set append-signature-post false
X#
X# The inews and mailer parameters may vary with your system's
X# setup, but to allow this script identify the _source_ of the
X# calling program, set the -N parameter with inews.
X#
X# If you have ~/.signature or ~/.Signature files, then delete them.
X#
X###############################
X#
X# Create a directory that contains all your .sig files.
X# I have used ~/.sigs here, but edit for your own tastes.
X#
X# Create a series of sequentially numbered .sig.* files, start at .sig.0
X# I have used .sig.0 .sig.1 .sig.2 etc; again edit as desired.
X# You can have as many as you like, but restrict them to only a few lines.
X#
X# Create two files called .head and .tail (in the ~/.sigs directory)
X# .head contains your usual "signoff" (eg, "Cheers \nTony")
X# .tail contains anything you want to finish off your sig, like
X#       a fancy one-liner or whatever.
X#
X# TO PREVENT THE INJECTION OF ANY .SIG:
X#  That is, to tell this script not to do its usual thing:
X#    - just add "noquote" to the end of your message!
X#    - be warned that any line of your message with "noquote"
X#      in the last few lines will be deleted from the message.
X#
X###############################
