How do I display tty stuff in X

jlturbos · 02-08-2004, 03:45 PM

Let's pretend I am compiling a kernel in tty1 then I log in to tty2 and startx as root. I know this is a nono, but I am only interested in figuring something out. Is it possible to start xterm in X and view what is going on in tty1, without doing a Ctrl+Alt+F1.

Thanks,
JL

interesting, but just the nature of your question
i am going to guess that the answer is no ....

i have no idea, nor did i research, but i cannot see how that is possible ....
but i am sure someone will enlighten us if you can in fact do it ..

if and if and if...

if X is already running:
if xterm is open

make > /dev/pts/x #where x is the device. find out number by running ps from xterm

will redirect the output to the xterm

I'm in FreeBSD right now and I tried:
make > /dev/ttyv2 #Because that's the terminal it's runnin' on.

I got a:
`/dev/ttyv6' is up to date.

Maybe this will work in Debian though.

Thanks.

if you open a 2nd tty, startx -- :1 & will start a 2nd X server.

when I compile kernel (everything in /usr/src/linux)
make .... >makeout 2>make.err
In xterm 2
tail -f make.out
in xterm 3
tail -f make.err
in xterm 4
while [ true ];do find . -type f -iname \*\.o -cmin -1; sleep 10;done
gives me a feel how things are running

I would look into using screen. Try "man screen"

I tried "watch" in FreeBSD and it works perfect.

Here's what I did:

I went to Ctrl+Alt+F3 or ttyv3 and typed:
"yes"
and then went to xterm in X and typed:
"watch"
This came up:
Snoop started.
Enter device name []:ttyv3
and there it was:
y
y
y
y
y
y
y
y

on so on...

Is there a "watch" command in Linux?

Look into screen, too. Its a nice program. Lets you start up a terminal within another terminal, then disconnect from it, and reconnect at a later time. You can start one up in an xterm, start a kernel compile, then disconnect, and reconnect from an ssh session from work to check on it.
