This is a simple Perl script for managing multiple hostfile configurations on *NIX systems. The hostfiles script is built on top of the Hostfile::Manager module. The module provides an object-oriented interface to managing a list of hostfile fragments and enabling or disabling them in a target hostfile.
To get started, create a directory /etc/hostfiles and place one or more files in the directory containing hostfile fragments. The fragment filename will be used to tell the hostfile manager what to enable or disable.
Using the hostfiles is simple. It has two primary options: --enable and --disable. You can specify each multiple times or pass comma-separated lists of fragment filenames.
For example, to enable a hostfile fragment called "staging":
$ hostfiles --enable staging
You can ask for the status of the available hostfile fragments by passing the --status flag:
$ hostfiles --status
+ local
$
The first character of the status ouput will be ' ' if the fragment is not enabled, '+' if it is enabled, and '*' if it is enabled and has been modified in /etc/hosts.
Passing the --interactive flag will ignore any --enable, --disable, or --status options and present a list of hostfile fragments that can be enabled or disabled interactively.
