Is there a good free (prefrerably PDF) bash tutorial online? [closed]

Question

I am finding myself doing a lot more messing around with scripts than I used to and my lack of knowledge in this area (and linux sysadmin/security in general), is becoming a hindrance.

Can anyone recommend a good online resource for bash scripting/linux admin. Preferably, it will be in pdf format, so I can copy it (single file) onto my PDA.

Answer 1

I've learnt much from the Advanced Bash-Scripting Guide

This guide is targeted more at programming beginners, but it can prove useful too: Bash Guide for Beginners.

I usually use the HTML version as a reference when hacking Bash, but there is a PDF version of both guides if you want to read them all through. You can find all formats of the guides at http://www.tldp.org/guides.html
