Getting tty name from script

How can I determine what is the current tty name? The only way I know is to issue "system("tty") > somefile" and read the file afterwards.

You don't need to redirect the output from the tty command to a file, this also works:

chop ($tty);
print "Current tty is: $tty\n";

Don't forget the chop, or you'll have a newline after the tty name.
