Linux setleds command
Linux Command大全
The Linux setleds command is used to set the status of the three LED lights above the keyboard. In Linux, each virtual console has an independent setting.
Syntax
setleds [-v] [-L] [-D] [-F] [{+|-}num] [{+|-}caps] [{+|-}scroll]
Parameters:
- -F: Preset options, set the status of the virtual console.
- -D: In addition to changing the status of the virtual console, it also changes the preset status.
- -L: Do not change the status of the virtual console, but directly change the status of the LED display. This will cause the LED display to be inconsistent with the current status of the virtual console. We can later use -The setleds command with L and no other options will respond normally.
- -num +num: Toggle the numeric key on or off.
- -caps +caps: Toggle the uppercase key on or off.
- -scroll +scroll: Toggle the option key on or off.
