Remote Desktop Manager's Auto Typing Macro is really helpful to simulate user interaction. It's mostly used to perform automatic logon on web pages, but you can run advanced shell commands on various operating systems.
Sometimes you need to confirm exactly what will be sent when using our Variables.
A simple trick is to create a batch file that just types out whatever is sent on the command line.
Just copy the following in your favorite editor and save it as a command file, I named mine parrot.bat
Now its a simple matter of creating a Command Line (External Application) session and set the command line to the path of the parrot.bat file and add the variables right after.
"C:\tools\parrot.bat" $DOMAIN$ $IP$ $USERNAME$
Now when you run the entry, you will see exactly what values are sent.
A reminder that for the password to be available as a variable, you must go in the Security Settings of the entry and check Allow password in variable.
