The conditions in the above scripts are driven by the values of the variables entered by the user, but
sometimes it is necessary to drive conditions from interactions with the switch. For example, if a switch
can be configured with either a blank password or no password (no password prompt) then the text
field for password is insufficient to specify the correct configuration. Instead the script can use a regular
expression to expect either a password prompt or no prompt, and drive subsequent commands from the
result.
