Basic Linux system auditing is a bit tricky and data collected and information of that is out of place and readability is not that good. Recently this lead me to put together a Open Source code project and develop simple BASH scripts that do the job nicely.
The code and tar ball can be downloaded from both google code or from source forge website's and the project website has links to documentation, help, installation and code.
