Logging into Docker Hub, or similar container registries, with "special" passwords

Note to self, if your password contains a special character such as dollar ( $ ), ensure that you escape if IF you're putting your password into a Bash environment variable, or passing it as a parameter to a Bash script.

Obviously, NOBODY would do that but .....

So, for a password such as: -

Qp4$$w0rd

it should be escaped thusly: -

Qp4\$\$w0rd

Again, do NOT use passwords in variables or on the CLI ......
