How do I run a command in a different tty?

Copy and paste this code on ttyecho.c

Compile it using gcc -O3 -o ttyecho ttyecho.c

Use it ./ttyecho -n /dev/pts/1 ls

Depends on your terminal environment:

• In Linux with the console: openvt _command_
• Within a terminal in screen: screen _command_
• Within X Windows (Mac as well): xterm -e "_command_"
