The command "rfkill -o ${ID,TYPE,DEVICE}" is used to display information about the wireless devices on a system. Here's a breakdown of each component of the command:
-
"rfkill" is a Linux command-line tool used for querying and manipulating the state of radio-frequency (RF) kill switches, such as those used to disable Wi-Fi, Bluetooth, or other wireless devices.
-
"-o" is an option that specifies the output format for the command. In this case, it tells rfkill to display the output in a specific format.
-
"${ID, TYPE, DEVICE}" is a parameter inside curly brackets {}. It defines the specific fields or columns that you want to be included in the output. The available fields are:
- "ID": The unique identifier for the wireless device.
- "TYPE": The type of the wireless device, such as WiFi, Bluetooth, or NFC (Near Field Communication).
- "DEVICE": The name or description of the wireless device.
So, when you run the command "rfkill -o ${ID,TYPE,DEVICE}", it will display the ID, TYPE, and DEVICE fields for all the wireless devices detected on your system.
