Ubuntu 14.04 Set up the boot script method _linux

Rc.local Script

The rc.local script is a script that will be executed automatically after Ubuntu is powered on, and we can add command-line directives to the script. The script is located under the/etc/path and requires root permission to be modified.

The script is specific in the following format:

#!/bin/sh-e # # rc.local # # This script is executed in the end of each
multiuser runlevel.
# Make sure that script would ' 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.
 
Exit 0

Note: Be sure to add the command before exit 0
