关闭树莓派的电源指示灯和状态指示灯

在命令行输入一下指令：

echo 0 | sudo tee  /sys/class/leds/led0/brightness   //状态指示灯,范围 0-255
echo none | sudo tee  /sys/class/leds/led0/trigger
echo none | sudo tee  /sys/class/leds/led1/trigger
echo 0 | sudo tee /sys/class/leds/led1/brightness    //电源灯

 如果要每次开机生效, 可编辑/etc/rc.local文件

sudo vi /etc/rc.local 

增加上面四行

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

# Print the IP address
_IP=$(hostname -I) || true
if [ "$_IP" ]; then
  printf "My IP address is %s\n" "$_IP"
fi

exit 0

echo 0 | tee  /sys/class/leds/led0/brightness
echo none | tee  /sys/class/leds/led0/trigger
echo none | tee  /sys/class/leds/led1/trigger
echo 0 | tee /sys/class/leds/led1/brightness
