Terminal Questions? "cat /dev/tty1" Why Not?
How come I can echo a tty device by doing "echo hello > /dev/tty1", but I can't cat a tty device? If I try to do a "cat /dev/tty1" in tty2 for example I don't see the output of tty1. I'm doing this as root by the way.
Lets say I log into X from tty1 using startx. I then go into an X session. Now I go to tty2 and type startx -- :1 and start anothr X session. alt F7 and alt F8 are my X session. What is the equivalent tty devices created on F7 and F8? Now while I'm in X I start up xterm. The device now is /dev/pts/1. What type of terminal is this and what relation does it have to the requaler tty's? While I'm in xterm I would like to see the logging output of X and the window manager going to tty1. How come "cat /dev/tty1" doesn't give the desired results? How can I redirct all output going to tty1 to /dev/pts/1? |
Hello!
Try "cat < /dev/tty1" and "dev/pts/1</dev/tty1" It should work!! See you! /edu |
??? huh
cat /dev/tty1 and cat < /dev/tty1 are the same thing dude. The first one say cat tty1 and the second says the input to cat is tty1. Identical? File1: a b c Then do, cat File1 ... a b c Then do, cat < File1 ... a b c Same thing bro. Anyway, cat < /dev/tty1 doesn't do anything either. |
Wow I gues my question is to advanced for you linux guru's. Nobody has any ideas on how to cat or tail or head or tee a tty device and see it's output in a different terminal?
