bash Style Or POSIX Shell Style?

[ldo]

Is this a style guide specific to bash, or is it for POSIX shells generally? Many of the tips seem to be bash-specific (e.g. use built-in expressions instead of expr), but then you say don’t use backticks because they may not work with some non-bash shell.

Maybe separate out the bash-specific tips from the non-bash-specific ones?

it says community bash style guide, does that answer your question? :)
