Hi magicians

I'm building a render farm with HQueue as the dispatcher.
Our farm is a mix of Windows and Linux.
When I send a command job ( generic generator ) from PDG, I have to send different commands for each OS.

For example
Linux -> /mnt/share/linux_bin/app --frame `@Frame`
Windows -> H:/win_bin/app.exe --frame `@Frame`

("/mnt/share" and "H:" are same network location)

What is the best way to send different commands for each OS?

Thanks
