It can be different for each process.

Look at /proc/NNNN for the process of interest.

Since the first three file are standard in (0), out (1), err (2)

    $ ls -l /proc/26670/fd
    total 8
    lr-x------  1 mitch mitch 64 Sep 30 16:36 0 -> /dev/null
    l-wx------  1 mitch mitch 64 Sep 30 16:36 1 -> pipe:[14054]
    l-wx------  1 mitch mitch 64 Sep 30 16:36 2 -> pipe:[14054]
    lrwx------  1 mitch mitch 64 Sep 30 16:36 3 -> socket:[203653]

So in this case the out and err are tossed into a FIFO
that is not inspected.  Use "lsof" to see what plays with the pipe...

Well, I was hoping of a more general solution, like having a log of everything that any X client dumps to the console on a given session (a /var/log/messages alike for X).


If X crashes I just can't go out and grab some client's console... (I don't even know the culprit then).
