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.

Hi,

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

#!/usr/bin/perl
my($tty)=`/usr/bin/tty`;
chop ($tty);
print "Current tty is: $tty\n";

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

#also:
use POSIX;
$tty=POSIX::ttyname(2);
