sh deploy.sh doesn't ask for password

I can run the helloworld examples, but is run 'sh deploy.sh' in the folder '/doc-samples/policy-mashup-cookbook' I get the following the following, with no option to add a password, any ideas please?

deploy.sh: 3: deploy.sh: source: not found

deploy.sh: 7: read: Illegal option -s
