Answer 1

Your question is very vauge, so I will answer it based on what you asked.

ssh -f -T ${USAGE_2_USER}@${USAGE_2_HOST} ${CMD}

this would ssh as the user assigned to ${USAGE_2_USER} to the host assigned to ${USAGE_2_HOST} and then run whatever you have assigned to ${CMD} and then return the output and then exit.

 13:17:41 up 9 days, 13:54,  7 users,  load average: 1.67, 2.19, 2.11
risk@DockMaster:~$ 

As a side note is the -f -T needed?
