autosign

A utility for use with the Mail User's Shell (mush)

by Magnus Olsson ([e-mail])


The Mail User's Shell (mush), by Dan Heller ([e-mail]), has options for
automatically appending your signature and/or a "fortune cookie" to all
outgoing mail. The options are rather flexible; for example, you can use one
signature for letters to certain domains and another one for other domains.

However, you may wish for greater flexibility than that provided by mush.
Version 7 (and later) of mush allows you to specify a program that is called
to sign your mail. autosign.c is an example of such a program.

Once you have installed it, every time you send a mail message you will be
given a menu of signatures to choose from. You select one of these and it is
appended to your message (you may of course also choose not to append any
signature at all). autosign will then call your system's "fortune cookie"
program to generate a fortune cookie. This will be shown to you beefore it is
appended, and you'll be given the options to either append it to the message,
or to generate a new fortune (this way, you can e.g. avoid appending rude
jokes to letters to your boss - many of the quotes in fortune databases tend
to be rather obscene), or not to append one at all.

No modification to mush is needed, only a line in your .mushrc file.

There is no Makefile (what use is that when the program consist of just one
file?) and no manpage either - the instructions in the README file should
suffice.

The Mail User's Shell (mush), by Dan Heller ([e-mail]), has options for
automatically appending your signature and/or a "fortune cookie" to all

Version 7 (and later) of mush allows you to specify a program that is called

Once you have installed it, every time you send a mail message you will be
given a menu of signatures to choose from. You select one of these and it is
appended to your message (you may of course also choose not to append any

Installation:
X
First edit the file autosign.c to suit your needs.
As it is, it gives you a choice of two different signatures. These signatures
should be kept in different files. The macros SIG1 and SIG2 should be defined
as the full paths of these files.
If you need another number of signatures than 2, you must define one macro for
each file. The "switch (ans)" statement must also be changed, but the
modifications are trivial.
The macro FORTUNE should be defined as the full path of the program to
generate fortune cookies on your system.
X
Then compile autosign with the following command:
cc -o autosign autosign.c
and move the resulting file autosign to somewhere in your path.
On some systems, such as Ultrix, you'll have to do a 'rehash', too.
X
Then edit your .mushrc file to contain the line
set autosign="| autosign"
X
That should be all!
X
X
Note:
X
This program has been tested on a DECstation 3100 running RISC Ultrix 4.1. It
has not been tried on any other system. It believe it should work on any
system running BSD 4.x Unix.
