    Please stop promoting horrible guides that teach unsuspecting newcomers to write bugs and not scripts.

    I think everybody who writes code (also beginners) should take a look at code-style-guides!

    e.g.: some month ago I added some content to the oh-my-zsh wiki: https://github.com/robbyrussell/oh-my-zsh/wiki/Coding-style-guide

    • Tobias Hochgürtel May 18, 2015 @ 12:21

      I agree with Code-Style Guides. Github can now support creators with Merchandise – nice to see :-)

    All you need is the Bash guide from http://mywiki.wooledge.org/BashGuide

    The rest is mostly garbage and bad practice. This is put together by the guys in #bash on freenode
