Behind the scenes

How are identified applicable files

  • File extensions: `,.sh,.bash,.dash,.ksh`
  • Detected file content (regex): ^#!/usr/bin/env bash, ^#!/bin/bash, ^#!/bin/sh

How the linting is performed

  • bash-exec is called one time by identified file (file CLI lint mode)

Example calls

bash-exec myfile.sh
