FileBot

Part of my filebot command contains "--def exec=" which calls on a command that uses a regex. Part of the regex uses curly braces to detect repetition i.e. {1,3}
The curly braces seem to break filebot: Is there any way to get around it?

{...} is interpreted by FileBot so you can't use those bash constructs in a FileBot exec expression.

I recommend creating a shell script that does the job and then simply call that with the appropriate arguments after you have tested it manually.
