NAME

rfkill - tool for enabling and disabling wireless devices

SYNOPSIS

rfkill [options] [command] [ID|type ...]

DESCRIPTION

rfkill lists, enabling and disabling wireless devices.

The command "list" output format is deprecated and maintained for backward compatibility only. The new output format is the default when no command is specified or when the option --output is used.

The default output is subject to change. So whenever possible, you should avoid using default outputs in your scripts. Always explicitly define expected columns by using the --output option together with a columns list in environments where a stable output is required.

OPTIONS

-J, --json

Use JSON output format.

-n, --noheadings

Do not print a header line.

-o, --output

Specify which output columns to print. Use --help to get a list of available columns.

--output-all

Output all available columns.

-r, --raw

Use the raw output format.

--help

Display help text and exit.

--version

Display version information and exit.

COMMANDS

help

Display help text and exit.

event

Listen for rfkill events and display them on stdout.

list [id|type ...]

List the current state of all available devices. The command output format is deprecated, see the section DESCRIPTION. It is a good idea to check with list command id or type scope is appropriate before setting block or unblock. Special all type string will match everything. Use of multiple ID or type arguments is supported.

block id|type [...]

Disable the corresponding device.

unblock id|type [...]

Enable the corresponding device. If the device is hard-blocked, for example via a hardware switch, it will remain unavailable though it is now soft-unblocked.

toggle id|type [...]

Enable or disable the corresponding device.

EXAMPLE



  rfkill --output ID,TYPE


  rfkill block all


  rfkill unblock wlan


  rfkill block bluetooth uwb wimax wwan gps fm nfc
