In all cases: <filename> can be - (stdin) Multichar options are expanded e.g. -abc becomes -a -b -c. The -- option suppresses option processing for subsequent arguments. Note that since filenames and jsonnet programs can begin with -, it is advised to use -- if the argument is unknown, e.g. jsonnet -- "$FILENAME".
