Setleds is the combination of the English phrase "setleds", and the translation into Chinese is to set the LED lamp. The setleds command is used to set the status of the three LED lights above the keyboard. In Linux, each virtual console has its own settings.

This is a very magical command that can be used to control the state of the keyboard lights. Then let me learn this command together.

Syntax format: setleds [parameters]

Common parameters:

-F sets the state of the virtual console-D changes the state and preset state of the virtual console-L directly changes the state of the LED display + num/-num turns numeric keys on or off + caps/-caps turns uppercase and lowercase keys on or off + scroll /-scroll turns the option keys on or off

Reference example

Control keyboard lights num lights on and off:

[root@linuxcool ~] # setleds + num

[root@linuxcool ~] # setleds-num

Controls the case key of the keyboard on or off, and the keyboard indicator on or off:

[root@linuxcool ~] # setleds + caps

[root@linuxcool ~] # setleds-caps

The option keys that control the keyboard are on or off, and the keyboard lights are on or off:

[root@linuxcool ~] # setleds + scroll

The combination of the three lights on and off, respectively set to digital light on, upper and lower case light off, the option key scroll light off:

[root@linuxcool ~] # setleds + num-caps-scroll above is all the contents of setting the status of the three LED above the keyboard using the setleds command of linux. Thank you for reading!
