HI:

When you use 'su -' you are causing the user's login profile to be executed. This sources (reads) the login profile to create a login-like environment with all the attendant enviornmental variable set just as a login shell would establish.

That's fine except for the fact that standard login profiles contain terminal-oriented commands like 'stty' and 'tset' which expect to be interactive with the controlling terminal.

Since there is no terminal associated with this process, you get the errors seen.

One way to circumvent this is to amend your '.profile' to *conditionally* execute terminal-oriented commands only when the process is associated with a terminal:

if [ -t 0 ]; then
...
eval ` tset -s -Q `
stty ...
fi

Regards!
