Net::OpenSSH::Parallel does not allow capturing directly the output of
commands into perl scalars. You have to redirect it to some file and
then reread it.
It would be easier to help you if you tells us what you need to do
from a higher level.

Hi Salva,
Thx for responding. I need to SSH into several nodes and run some commands
there and capture the modified output to a file on local node from where the
script is run.
