This script is almost entirely based on the work of @Bretterteig. This project is purely designed to package up the script with a suitable python distribution for anyone who does not push a generic python to all clients.
Whatever runs this script requires Full Disk Access. For example, if you are running from Terminal, you must enable Full Disk Access for Terminal in the Accessibility settings.
Use the launcher.sh script to add servers directly from the command line.
sudo /Library/Management/FinderServerFavourites/launcher.sh --add --server "smb://some.server" --server "smb://another-server.com"
You can specify an alternative user with the --user SOMEUSER argument.
Upload the script Jamf-FinderServerFavourites.sh to Jamf and add it to a policy which also has the supplied package attached. Set Parameter 4 to either add or remove, and use all the remaining parameters to specify servers.
