Hi All,
I'm running a distributed application on a cluster using J and I need a verb
that returns the IP (or hostname) of the node on which the jconsole is
running.
Thanks for any help.
Assuming you are in a _NIX environment, 2!:0 (Host) is
the key - e.g. I would use:
host 'echo $HOSTNAME'
focus
where host is defined as:
host
[: 2!:0 '('"_ , ] , ' || true)'"_
You might choose to make a simpler verb with just 2!:0
but the extra stuff in the above definition makes it
more useful in that it always returns a result, even if
the expression passed to the host has no result.
