If you actually want the command to be run in parallel across all the
devices you can use Salt.

If not and you are happy for this to be run in series you can use
ciscocmd (an expect script,
https://sourceforge.net/projects/cosi-nms/files/ciscocmd/), NAPALM
(this is like expect but in Python,
https://github.com/napalm-automation/napalm), RANCID (also builds on
expect), Anisible (using SSH, https://www.ansible.com/) or write a
multi-threaded wrappar in C/Go/Python.

Cheers,
James.
