cbd9091ed5a76bb2e1e57cd0d8db035c15529341 refactor/lint: Add ignored suggestions to an array (Vidar Holen) Pull request description: By adding excluded shellcheck suggestions to an array, you can avoid the current duplication between command and comments. This ensures that they never go out of sync, makes it easier to add new ones, and improves the readability of related diffs.
