Hello~~~

I want use a terminal to display the error message which comes from
stderr.
  I find a solution is redirect the stderr to a FIFO special file and
use a loop to read it in another terminal.
But it's not convenient. :(

  I want to use "write" commend but I have no idea about how to
redirect stderr to it?

Could you kindly find a good solution for me.  Thank you~~~

let's see if I understood correctly:

term1:

bash-2.03$ tty
/dev/pts/1078
bash-2.03$ cat nothing > /dev/pts/1099 2>&1

term2:

bash-2.03$ tty
/dev/pts/1099
bash-2.03$ cat: cannot open nothing



Hth,
