Rfkill: Small Command Line Utility for Wireless Device Managements

A lightweight Linux utility for enabling and disabling wireless devices using RF kill switches, with features like device status viewing and radio communication control.

What is Rfkill?

Rfkill is a simple command line tool in Linux that allows users to view and change the status of RF kill switches on wireless devices. RF kill switches are hardware switches that can turn on or off the radio communications on wi-fi, bluetooth, and other wireless devices.

With rfkill, you can check if any wireless devices have been hardware-disabled or soft-blocked in software. The utility will list device types (wifi, bluetooth, etc) along with a soft and hard block status for each. You can then use rfkill to unblock or re-enable any wireless devices that were disabled.

Some common uses for rfkill include:

• Turning wifi or bluetooth on or off manually
• Troubleshooting why a wireless device is not working
• Unblocking a wireless device that was accidentally soft or hard blocked

Overall, rfkill gives users control and visibility over radio communication devices that have an RF kill switch. It is handy for managing power to these devices or diagnosing wireless issues in Linux.
