Linux quickies are short code snippets (shell scripts, perl ...), which could help you to do a specific task. A lot of these snippets are born as answers in mailing lists and internet forums, others come from my scripts. They are often only a recommendation how to solve a problem - you are not prevented from studying and testing the code ;-)
I sorted the snippets by topic, language and used unix / linux commands. Partionally I modified the original posts, fixed syntax and program errors, wrote (hopefully) better explanations. To walk around the items, you have these possibilities to select the entries you want to look at:
The most recent articles (sorted by the date, when I added the article to this collection)
The articles providing a step-by-step tour through the code
Parts of shell programming like loops, conditions, command substitutions, ...
Unix/ Linux commands
The used commands (not shell builtins)
Sorted by topics, that means the questions "What do I want to do?" or "For which purpose is it useful?".
You'll find some "exotic" languages like sed or awk too. I listed articles under these sections, when they use more sophisticated features like functions, goto's or flow control. The commands themself appear in much more code samples.
