                Notes

                Note

                If you want to run a command through the shell (say you are using <, >, |, etc), you must specify a shell in the command such as /bin/bash -c "/path/to/something | grep else"

                Note

                The question, or key, under responses is a python regex match. Case insensitive searches are indicated with a prefix of ?i

                Note

                By default, if a question is encountered multiple times, it’s string response will be repeated. If you need different responses for successive question matches, instead of a string response, use a list of strings as the response. The list functionality is new in 2.1
