i see. so the "eval" line is inside the script and its effect is to redirect
stdin/stdout for the script.
very cool. thanks.

I must have missed something here. Where is the script that is being run?
example:
#!/bin/sh
echo Before redirection
ls -l /proc/$$/fd/0
tty
exec < /dev/null
echo After redirection
ls -l /proc/$$/fd/0
tty
# rest of the script here...
exit 0
(tty tests the tty on its standard input)

If you run "exec" without giving it a parameter, it will not execute
anything, but the redirection will take effect.
"exec < /dev/null >output 2>&1" will do what you want.
Fantastic!
Thanks to you and Yedidyah for the friendly reminder.
