    virtual terminal

    hi,
    tried running the command 'cat < /dev/tty7'
    which caused the terminal to execute an inifinite loop. On closing the window and opeing the new one the infinite loop didn't terminate. it did only when i pressed ctrl+d.

    Can anyone provide some logic behind this behaviour????

    why an infinite loop??

    Thanks.

    Most distros run their graphical desktop on /dev/tty7. So if you open a terminal on the desktop and then cat from /dev/tty7, I'm not surprised you get an infinite loop.

    btw, when I tried to do this just now, I wasn't allowed to; only root has read access to this terminal. And when I tried doing it with gksu, I got a gtk error.

    my confusion is not the infinite loop but its existence even after I close the terminal and open another one?
