These scripts are used for simple management of hostnames for several VirtualBox VMs comprising a test or sandbox environment on your local machine.

Architecture:

1. each VM is configured to use bridged network adapter, so all VMs and the host can see each other

2. a script is installed in each VM to run on post-ifup, which grabs VM's IP, puts "$IP $desired-hostname $desired-fully-qualified-hostname" into /etc/hosts, changes hostname correspondingly, and puts VM's hostname and fq-hostname into VM's properties

3. a script is used on the host machine, which loops through running VMs, and updates /etc/hosts on the host machine and on the VMs

# This code is originally from http://stackoverflow.com/questions/59895/can-a-bash-script-tell-what-directory-its-stored-in

# It is a useful one-liner which will give you the full directory name of the script no matter where it is being called from

DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"

# Or, to get the dereferenced path (all directory symlinks resolved), do this:

DIR="$( cd -P "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
