我想向/etc/rc.local
文件中添加两个省电命令。
禁用蓝牙:
rfkill block bluetooth
这会降低屏幕亮度:
echo 3024 > /sys/class/backlight/intel_backlight/brightness
单独添加/etc/rc.local
它们可以工作,但不能像这样一起添加:
#/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.
echo 3024 > /sys/class/backlight/intel_backlight/brightness
rfkill block bluetooth
exit 0
如何添加这两个命令才能使它们在启动时正确执行?
更新
原来是时间问题。我通过延迟执行第一个命令来解决这个问题:
(sleep 5; echo 3021 > /sys/class/backlight/intel_backlight/brightness)&
