Shell script (on Mac OS) to SSH into a Linux/Unix server and run a command

Question

I want to write a shell script to run on a Mac OS system that will do something along the lines of the following:

I would assume it'd be something like this:

ssh user@ip --[some kind of key auth flag here]
command --whatever-flags-here

Unfortunately, I don't have a Mac nor do I have any experience using them at all so I'm hoping you guys can help me out with this one.

Your question is not related to programming. superuser.com is a better place to ask. — Nikolai Shevchenko

You can do it like this:

ssh user@ip [ssh-options] "command1; command2; command3; ..."

For example:

ssh user@ip "touch test.txt; cp test.txt test2.txt"

will create the two empty files test.txt and test2.txt on the remote machine.

Another approach would be to use a stdin redirection

ssh user@ip [ssh-options] < your_commands.sh

where your_commands.sh is the script that will executed on the remote machine.
