This is a quick and dirty AWK tutorial demonstrating the most common usages and features that one can use on a daily basis.  Three variants: AWK standalone, integrated into ksh, and one-liner are provided. 
 
On my system, AWK pointed to GAWK.  GAWK has an expanded command set but here we will only focus on specific [...]

Just happened to have forgotten a password for one of my user accounts on my workstation and remembered a handy little thing one can do to reset a pass.
If you have root access, one can simply regenerate the MD5 hash with:

In this post we'll configure network booting through PXE.  PXE stands for Preboot eXecution Environment and has been available for Network Devices (or NIC's) for some time.  Such a network boot setup has many uses in particular in OS setup and deployment.  In this post I'll introduce the steps to quickly set one up.  [...]

So you've lost the password to the root account.  Worst, you've had a boot password and it was the same.  Here are some instructions on how to get back into your system:

This post is designed as a blind test, meaning its sole purpose is for testing and learning LVM functionality.  In this process we will work with an existing LVM that contains live data to grow, shrink and move it's contents around.  Before we do anything, a disclaimer is in order:

The VLC player is rumoured to be one of the best players to day for playing many different formats including mts and m2ts proprietary SONY formats. (Which just so happens to be the format of my Camcorder movies)  This is the way my camcorder has been saving them in and to date, there are [...]

For this howto we will be using the TP-LINK line of USB wireless cards.  More precisely the 54Mbps TL-WN321G and the 300M TL-WN821N adapters otherwise known for running the Atheros Communications, Inc.  Atheros eXtended Range™ technology.  This is an important note because this is how this card will appear under Linux.
