Recommended online resources for learning bash scripting

Question

When I first began bash scripting I spent a lot of time online trying to find resources for various tasks and things were scattered across tons of different forums and newsgroups.

I'm not completely sure if the idea of a list of resources for those new to bash scripting is something fitting of SO's community wiki or not. I'm posting on the assumption it will be down-voted if this isn't befitting.

Please post any online sources you find very useful either as an administrator or that you found useful during your learning process.

Answer 1

The two best resources I've found are:

http://www.shell-fu.org/ - which gives you a cookbook style approach to learning scripts . this can often be quicker than learning a reference guide.

http://tldp.org/LDP/abs/html/ - which gives you the a complete reference to Bash.

I've used both of these. Hope that helps. The Bash Cookbook by OReilly is also very good.

Answer 2

If you like "computer based training" (i.e. videos), I find that LinuxCBT is a pretty good resource.

They have courses on Bash and other scripting languages.

Answer 3

Check out commandlinefu and these two articles for some great bash tips.

Answer 4

Linux Shell Scripting Tutorial - A Beginner's handbook

Answer 5

Bash Programming intro HOWTO and Advanced Bash scripting howto

For examples of usage (when you're not sure) check out scripts on your system in /etc/rc.d/

Answer 6

Advanced Bash-Scripting Guide

You can download it and keep it as a local reference.

Answer 7

A small and incomplete list of some guides/tutorial

Don't take the ABS too serious. It's a great collection and a good guide, but it's not (A)dvanced.

bash-hacker.org/wiki itself may or may not be of interest, the focus is not directly to provide tutorials, more background- or base info (like grammar and syntax).

Answer 8

The two best places are probably http://tldp.org/LDP/abs/html/, and http://mywiki.wooledge.org/BashGuide. the bash faq at http://mywiki.wooledge.org/BashFAQ is well worth taking a poke through for regular gotchas as well.
