scripting question

Shell Programming and Scripting
1

I'm new to shell scripting and am having a problem trying to do something in C shell. I want to write a script that will input something instead of a user doing it. For example, using the command 'write' the user is supposed to type something to be sent to another user. I want a script to be able to send the message.

write is an interactive command (do a man write).. so it can't be used in scripts... there are no non-interactive options that I know of with write...

by default you are not permitted to write to another terminal... both users should allow write using the "mesg" command...

Cheers!

Have a look at Expect, it should be able to do what you are asking.

write can be used in scripts (at least the versions I've used).

#! /bin/sh

echo "\nHello there!\n" | /usr/bin/write username

or if you've got a longer message, this should work:

#! /bin/sh

/usr/bin/write username <<EOF

Hello there!
I was just
looking though
all of your files, 
and found your
 purity test! You
dirty bird, you!
