Usually in Linux systems the scripts in /etc/rc.d or init.d are executed during boot, rc.local usually being the last one. That's the most direct way I can imagine..

Wait a minute, you want a program/app to be invoked during bootup that waits for actual user input?

Perhaps you mean that the program must run just after a user (or any user) logs in? In this case you could start the program by inserting its path into "~/.profile", or?
In my case I wanted to start up X whenever the user was logging in through the console that appears just after the boot sequence ends, but not when other users (or the same one) was logging in through ssh or other local terminals, so I wrote the following .profile file:

Code:

VIA ~ # cat ~/.profile 
echo "This is your .profile script"
TERMINAL=$(tty)

if [ "$TERMINAL" = "/dev/tty1" ]
then
        echo "This is the main terminal, so I am starting up X"
        /home/shared/scripts/startx_custom
else
        echo "This is a secondary terminal, so I won't start up X"
fi

The name might be different and if it does not exist yet, jut create it. In my case it wasn't existing. And yes, I use Bash as a terminal and normally the bash file is called ".profile", but I don't exclude that in your case it might be called ".bash_profile".
