try on your machine
The "rfkill" command is used in Linux to manage wireless devices, mainly to enable or disable them.
The "-J" option is used to format the output of the "rfkill" command as a JSON object. JSON (JavaScript Object Notation) is a widely used lightweight data interchange format. When the "-J" option is provided, the "rfkill" command will output information in a structured JSON format, making it easier for other programs or scripts to parse and manipulate the data.
Using the "rfkill" command with the "-J" option can be helpful when you want to write scripts or programs that require information about wireless devices and their current state.
