The files in this gist are for having Jenkins automatically manage a chef repository using git submodules. This allows for clean, clutter free management of individual cookbooks, and individual respositories for roles, environments and data bags in our chef-repo.

The process relies on using Github (we use Github Enterprise) and Jenkins in combination with the Jenkins Github plugin to notify Jenkins when a repository has changed.

Our chef-repo directory looks something like:

chef-repo
    - cookbooks
          - Each cookbook is a git submodule managed by Jenkins
    - data_bags (git submodule managed by Jenkins)

Using "lsof" in the Real World
==============================

by Chris Harrison, October 2008

lsof ("LiSt Open Files") is a tool to list open file handles on a server. Being able to filter these handles using the range of options and switches for lsof allows the Solaris administrator to diagnose a number of problems.

This guide explains a couple of the command-line options to lsof, and then shows several examples of how lsof can be used in the "real world". (Note: This should work on all Solaris versions from 8 onwards; it might work on earlier versions, but I've not tried it.)

Obtaining "lsof"

def get_version(project_root):
    process = subprocess.Popen(
        ['git', 'describe'],

# The VirtualBox documentation[1] for how to install guest additions 
# for Linux on a virtual host is somewhat messy. So here is what 
# I did to make it work.

# Install the packages required
yum update
yum install gcc kernel-devel make
