HP Switch SSH Script

I am trying to create a script to ssh into an hp switch and grab both the running and startup configs.

I have access to both linux and windows, running into an issue on the linux side with ssh command execution is not supported, and on the windows side using powershell to sendkeys to the ssh window and run the copy command.

The basics of the script for both can create the ssh session, but my linux script is the only one that can send the password successfully. Once I try to send any commands it stops dead on "SSH command execution is not supported".

Any ideas would be appreciated.
