Wrap HOTDEPLOY in quotes.

-n string is not null.

    The -n test requires that the string be quoted within the test brackets.
    Using an unquoted string with ! -z, or even just the unquoted string
    alone within test brackets (see Example 7-6) normally works, however,
    this is an unsafe practice. Always quote a tested string. [1]
