Give the path to the command, either on the local machine or on the remote machine, as defined in the environment parameter
Relative paths can be written simply with the white spaces included. You will need to use quotes (") around the path or command if you are using path fragments (e.g ./ or ../) for the relative path.
Please bear in mind that strings within quotes are not checked for validity.
The backslash character (\) is interpreted as the escape character. If you want to use a backslash, which you will most likely do, type in a double backslash (\\).
