Running scripts on boot

The Linux kernel in the Opengear console server supports GNU bash shell script. If there is a file installed at /etc/config/rc.local then any commands in that file will be run on boot. For example here is a hello world script:

#!/bin/sh
echo "Hello World!"
echo "Goodbye World!"

If the script has been copied from a Windows machine you may need to run the following command on the script before bash can run it successfully:

# dos2unix /etc/config/rc.local

GNU bash, version 2.05.0(1)-release (arm-OpenGear-linux-gnu) supports the following shell commands:
