Read input from another tty
Hello,

I am trying to find out how I can find the tty number of a terminal a bash script has just created.

Ultimately what I am trying to achieve is a script that starts a new terminal where stderr can be directed to.

Code:
ls -l missing_file 2> /dev/pts/X

To find the tty number of the new terminal I have

Code:
#!/bin/bash
tty_current=`tty`
echo $tty_current
xterm -e "tty > $tty_current" &

This will output the tty number of both the "parent and child" terminals.

My problem is how can I read in the output from the new terminal?

Are there any other methods people know of to achieve the same thing?

Regards,
Colin

ttytype

TTYTYPE(5)						     Linux Programmer's Manual							TTYTYPE(5)

NAME

       ttytype - terminal device to default terminal type mapping

DESCRIPTION

       The  /etc/ttytype  file	associates termcap(5)/terminfo(5) terminal type names with tty lines.  Each line consists of a terminal type, fol-
       lowed by whitespace, followed by a tty name (a device name without the /dev/) prefix.

       This association is used by the program tset(1) to set the environment variable TERM to the default terminal name for  the  user's  current
       tty.

       This  facility was designed for a traditional time-sharing environment featuring character-cell terminals hardwired to a UNIX minicomputer.
       It is little used on modern workstation and personal UNIX systems.

FILES

       /etc/ttytype
	      the tty definitions file.

EXAMPLE

       A typical /etc/ttytype is:

	      con80x25 tty1
	      vt320 ttys0

SEE ALSO

       termcap(5), terminfo(5), agetty(8), mingetty(8)
