use ssh to run shell script on a remote machine

Also, don’t forget to escape variables if you want to pick them up from the destination host.

This has caught me out in the past.

For example:

user@host> ssh user2@host2 “echo \$HOME”
prints out /home/user2

while

user@host> ssh user2@host2 “echo $HOME”
prints out /home/user

Another example:

user@host> ssh user2@host2 “echo hello world | awk ‘{print \$1}'”
prints out “hello” correctly.
