Because, as users look on to a system, they are given different tty's.
The first user to log in gets /dev/tty0. The second gets /dev/tty1.
The third gets /dev/tty2. And so on.
The device /dev/tty is a special one. For each user it is mapped
to their /dev/tty? device... whatever that may be. So, if you are
writing a shell script or something, you can always redirect output
to your own script (instead of a file or something) by writing:
echo "Something" > /dev/tty
and this will automagically forward this to your tty-device (whatever
that is). So if you are on /dev/tty9, this will be the equivalent of:
echo "Something" > /dev/tty9
The /dev/tty aliasing just makes things easier for script writers and
programmers.
