> Is it possible you have two processes on tty1 both trying to read?
At first I thought this was impossible, but remembered that the top process
I created
in inittab:
c9:23:wait:/usr/bin/top >>/dev/tty9
This process started acting strange since upgrading to procps-1.01. With
v.0.99a
I was able to use keyboard commands from tty9 to control the output of top,
but
with v.1.01 keystrokes from tty9 were ignored. I now remember that top
sometimes
showed a prompt when I switched from tty1 to tty9, waiting for input (but
ignoring
all input from tty9).
I now think that top was reading stdin from tty1, disregarding the
redirection to tty9.
My tty1 is fine when I kill top in tty9 (I have commented that line out in
inittab).
Is this a bug in procps-1.01, or is there another way to redirect top to an
unused tty?
