Hey guys. You are totally right so far. I forgot to add my try.
The problem was how to add the credentials. Well the problem still exists but now I was able to add the public key to the webserver.
So now it is working without entering user and password.

The so far working code is:
Code:
FILETOCHECK=/test.txt
if ssh 'user0815@example.com' stat $FILETOCHECK \> /dev/null 2\>\&1
            then
                    echo "File exists"
            else
                    echo "File does not exist"

fi

Thank you.
I was not able to do with pwd authentication. If you know how to do so, please post it, because then we have a 100% solution on the topic.
Jens
