Services
Start CRON Daemon at startup
If you want to run CRON Daemon at startup, you can easily do it by creating a new file containing the launch of the crond program. After that, you would create a symbolic link from this file into the /etc/rc.d directory.Follow these steps :
| 1. | # Create the new file /etc/init.d/crond |
| 2. | $ cat > /etc/init.d/crond << EOF |
| 3. | #!/bin/sh /etc/rc.common |
| 4. | # Copyright (C) 2006 OpenWrt.org |
| 5. | |
| 6. | START=96 |
| 7. | start() { |
| 8. | /usr/sbin/crond -b -L /dev/null |
| 9. | } |
| 10. | EOF |
| 11. | |
| 12. | # Make a symbolic link into /etc/rc.d directory : |
| 13. | $ ln -s /etc/init.d/crond /etc/rc.d/S96crond |
GPIO
LEDs
| 1. | # Switch on light (where xx is the GPIO's number of the led) : |
| 2. | $ echo 1 > /proc/gpio/xx_out |
| 3. | |
| 4. | # Switch off light : |
| 5. | $ echo 0 > /proc/gpio/xx_out |

Storage
Retrieve USB storage folder dynamically
| 1. | # Just replace the size of your USB Key (here 498.0M) |
| 2. | $ df -h | grep 498.0M | cut -f 2 -d '%' | cut -f 2 -d ' ' |
