bash coding standards?
i didnt care about how i wrote my bash scripts, coz i know theyd ultimately be used just by myself. but for the past few day, i've been working on this project, mk-blog which uses some bash scripts, there are chances that others might look at them. besides in work they're asking me maintain a server. so why not learn the standards. but i couldn't find anything good online (i'm gonna blame my search engine lol). so...
i'd appreciate redirections to (official or community) bash coding standards

How do you unit test something like that?
I haven't used it on a project for money, but I have some tests in shunit2 and that alone encourages me to extract code to functions.
I had several tests at the beginning of the script. These tests define the "low-level" functions based the capability of the shell. To test new features I "simply" ran all the necessary commands on the test environments (bash, busybox, toybox+mksh).
The script would error out if some necessary capability was missing from the host system. It also had a feature to switch shell if it found a better one (preferring busybox and its internal tools).
Yeah... It was tedious process. It was one of those "I'll write a simple script. So simple that it'll work on almost every posixy shell."... rest is history.
