So I have a *NIX box (CentOS 5.5) which runs a number of background processes, I leave it on 24/7 with just a terminal up on the screen (I don't have Gnome, KDE or any similar graphical frontend, just a prompt).
Is there any way to get my background scripts to send content to the terminal (I.E. 'Running script XXX') whilst still leaving the terminal available for me to type commands when needed? Even if it was just simulating the keyboard typing 'echo "Hello World"' into the terminal or something?

Modify the scripts to write to syslog using logger. You can then configure syslogd (syslog.conf) to redirect these messages to the console.
