UNIX Scripting

How do I simulate keyboard input into my script? I am writing a script to shut down one of my application programs. The command to shut it down is sc stop. The application will pause and ask for a password to be entered. How do I put the password in the script so that the application won't pause for the password? Please help !!!

This may or may not work, depends on how the application was written...

#!/bin/sh
/dir/dir/sc stop <password
EOF

Replace /dir/dir and password with whatever is appropriate for your needs.

You could try writing a script that does the following:

#!/usr/bin/sh

echo xxxxx | "sc stop"

The above says that echo xxxxx(which represents your password) to the command sc stop. This should work although it is not advisable to put the password in a shell script as it is a security risk.

Try a program called "Expect" It will expect certain things from a script that's interactive. Then do something. http://expect.nist.gov/
It's really good for automating interactive applications.
