Convert script shebangs from "#!/bin/bash" to "#!/usr/bin/env bash" This is especially important for distributions like NixOS where `/bin/bash` doesn't exist, or for MacOS users who've installed a newer version of Bash than the one that comes with their OS.

Bash scripts; use double brackets, fix bare variables, add quotes These scripts explicitly use Bash, so we should be able to use `[[` instead of `[` (which seems to be recommended). Also added curly brackets to some bare variables, and quoted some paths. This makes my IDE a bit more silent :-) Signed-off-by: Sebastiaan van Stijn <github@gone.nl> 2018-12-22 19:18:33 +00:00			`if [[ ! -r "$changelogFile" ]]; then`
