Tutorial (not completely finished) I gave together with Rodrigo Galladro at Congreso Nacional de Software Libre (CONSOL 2002). There are many aspects in this tutorial that are just outlined, but I hope you find it useful.
You can grab the source LyX document; it is available also translated to HTML and as a PDF document.
As a complement, you might be interested also in the advanced Bash tutorial outline I prepared for a talk in late 2007; it is based on Octavio Ruiz (Tacvbo)'s tutorial. It only mentions the points I went over, but still, it can be a useful compendia.
