#
# CHANGELOG
# 
# Apr 15, 2012: Updated code to work with Ubuntu 12.04
#
# 	May 16, 2008: Corrected a typo on line 43 which prevented the r8169
#		module from being renamed. Thanks to linuxnotes.blogspot.com
#		for spotting it.
#
#	Jun 1, 2008: Added a bunch of checks to beef up the script a bit.
#		Removed all reliance upon the internet, as it is more than
#		likely the case that this script is being run without
#		connectivity. Added better output in case of failures.
#
#	Jun 2, 2008: Simplified many of the if statements to simpler checks.
#		Added a few more, and created the die() function.
#
#	Jun 4, 2008: Moved the stuff to removfe r8169 to the beginning.	This
#		makes the depmod command behave correctly, finally! Also fixed
#		the insmod check so that it no longer incorrectly dies. (Good
#		news!) Updated the die command to delete rogue $TMP folders in
#		case the script dies before completion. Also added more output
#		to help with debugging.
#
#	Aug 13, 2008: Updated the code to work with version 8.008.00 of the
#		Realtek driver. The new code no longer needs to be patched,
#		which was sort of the *magic* of the previous versions of this
#		script. Still a useful quick-fix script, though.
#
#   Nov 7, 2008: Updated package for 8.009.00
#
#   Aug 17, 2009: Updated package for 8.013.00, added a .ko, etc.
#
#   Oct 18, 2009: Updated package for 8.0.14.00, including a patch for
#       kernels >= 2.6.31.
#
#   Oct 26, 2011: Changed so that it works for linux 3.0 (Ahtenus)

Hi gist,

I'm trying out your script here, I got into trouble with "You need to install package linux-headers-". I'm a newbie and such a lazy ass :) I'll try to google it though after this, but just wondering if that could be automated to into the script :D

Regards,
Erik

just realized that was a stupid suggestion hahaha!
