Shell Script to do SSH followed by further commands

Usually in a shell script you can write commands such as

command1
command2
command3

and they will be executed one after another.

I want to write a Unix shell script to SSH onto a server and THEN execute commands on that server. For example

ssh [email protected]
ls

I try to do this as shown above but ls doesn't display output. What am I doing wrong?

Although the other answers to my question have been fantastic, I ended up using a small modified version. Thought I'd share it with the forum for anyone who's interested.

ssh -t [email protected] "
command1
command2
command3
bash -l"

advantages: it doesn't log you out!

Many thanks to anishsane and John Kugelman

Use Passwordless SSH as mentioned in this guide.

And then your script will contain:

ssh [email protected] command1
ssh [email protected] command2
ssh [email protected] command3

You can feed in commands to ssh on the command line or on stdin. If you have just one command to execute, do:

ssh [email protected] ls

If you have multiple commands, use heredoc syntax to pass them in via stdin:

ssh [email protected] <<END
command1
command2
command3
END
