#!/usr/bin/env bash is necessary if you are using bash. But don't use
bash.

Here are some useful references on sh.

Adherence to standards and legibility can be problematic if you care
about
portability to sucky systems and shells. For example, `...` is more
widely
supported than $(...). But in the case of stali, I suggest that non-suck
should
take priority over portability.

Many portability issues come about from slight differences in utilities
on different
operating systems. Here are some notes on utilities that I have had
issues with.
