Hi there!
=20
I noticed that I can chain commands together in that fashion. However, =
I'm trying to write a generic handler for issuing multiple commands on a =
box - I want to be able to check return codes, ouptut, etc, before =
moving onto the next command; of course, I also want the commands to be =
in the same shell.... :-) I have some (nasty) work arounds, but I'm =
really hoping I can get this working first.
=20
Regards,
Joe

	Hi !=20

	The documentation says so and You say so but that does not work. At =
least the results are not what You want.=20

	I had a similar case. On a HP-UX machine I wanted to import an Oracle =
export file which my Perl script had transferred using FTP. To use =
Import I have to setup the environment first (first command) using a =
shell script. However I'm certain that SSH 2 was used but the =
environment settings were lost while issuing the second command =
(import).

	To maintain the environment setting I had to chain the two commands =
into one command.=20
	Using Your example something like this:=20
	($out,$err,$rc) =3D $ssh->cmd("export FOO=3DWIBBLE";"print $FOO";);=20

	That should work irrespective of the SSH version.=20
