I am using ssh on my linux to remote access a second linux. What ssh does is to make my Linux's Terminal the remote Linux's Terminal, and whatever I entered in my Terminal would be executed on the remote Linux. Now I want to use a Shell script to enter a command after the remote access has been established.

I use the following bash to do the ssh part:

#!/bin/sh
ssh [email protected]

after this it prompts a password which is fine, I enter the password and the I am connected to the remote host. but after that I need to enter some additional commands to be executed automatically ( also from shell script) but simply entering them after the above code lines doesn't work.

Any ideas how to do this?

Tell ssh to send them to the remote shell to be executed.

#!/bin/sh
ssh [email protected] << EOF
./foo bar 42
cat baz/quux
EOF

This creates an interactive session. On my machine this means I get a "Pseudo-terminal will not be allocated because stdin is not a terminal." warning and also the multi-line "Welcome to Ubuntu" login message.
@Ignacio Vazquez-Abrams great it works, but it executes the second one after the first one is done, adding & to end of lines doesn't work either? can i somehow execute them simultaneously?

Put the command at the end:

ssh [email protected] echo foobar

To execute multiple commands, use a multi-line string:

ssh [email protected] '
    echo foo
    echo bar
'
