OpenWrt LED night mode

This simple script allows to disable all router LEDs (except power-on) at once, or enable them by resetting to default settings.

Can be useful for anyone who doesn't like LEDs blinking in the face at night.

Add something like this to crontab:

0 21 * * * /root/openwrt_leds_control.sh disable_all
0 6 * * * /root/openwrt_leds_control.sh reset

for file in /sys/class/leds/**/brightness; do echo 0 > "$file"; done

for file in /sys/class/leds/**/enable_hw_mode; do echo 1 > "$file"; done

echo "Usage: $0 {disable_all|reset}"
