Here's one script, I found it somewhere in the net, long time ago...
It gengerates HTML report for most of the important system files. See the usage at the start of the script. It works for RHEL, FC*; you need to be root to execute this, also, you may add any system env as per your wishes.

#!/bin/bash
# Description: Linux System Information Report in HTML format
