Hanging commands
Hello,
I just tried to run this command: /usr/lib/sendmail -d0.1 -bt < /dev/null | grep -i version
Its doing what I want: writing out the sendmail version.
But on some machines it writing the version and then exit to the prompt but on others its writing the version but then hangs, I need to break it with CTRL-C.
Can I break the this command with another shell command? Or sen CTRL-C with a command?
Im writing a script searching (with ssh) through 120 Sun mashines, dont want to have to log on every machine and look.

pconsole
PCONSOLE(1) General Commands Manual PCONSOLE(1)
NAME
pconsole - parallel console shell for administering clusters.
SYNOPSIS
pconsole
DESCRIPTION
pconsole allows you to connect to each node of your cluster simultaneously, and you can type your administrative commands in a specialized
window that 'multiplies' the input to each of the connections you have opened. pconsole is best run from within X Windows, although it is
possible to employ it without X (in console mode) as well.
You need to install pconsole on only 1 machine in the cluster, this would usually be your central administrative node.
OPTIONS
pconsole need to be executed with superuser permissions, and enters in interactive mode let you attach other devices so that all the com-
mands sent to the console mode of pconsole are sent to the devices. This allows you to parallelize the execution of the same command in
various machines at a time.
pconsole has two working modes:
command mode
From this mode pconsole can attach and dettach devices, list the attached devices at a time, connect to sending mode where you can
send commands to the attached devices, and quit. To enter in command mode, use CTRL-A from sending mode.
sending mode
The mode where the commands sent to it are sent to the devices attached. To enter this mode use CTRL-D or use the console command.
