Custom Script Header Example

This example shows how to replace the script header by simply placing a file called header.sh in your src folder.

Under most circumstances, you should not do it, and instead put your initialization code in src/initialize.sh.

This example was generated with:

$ bashly init --minimal

name: download
help: Sample minimal application without commands

args:
- name: source
  required: true
  help: URL to download from
- name: target
  help: "Target filename (default: same as source)"

flags:
- long: --force
  short: -f
  help: Overwrite existing files

src/header.sh

#!/usr/bin/env bash

# This is a custom header that will be injected to the very top of the 
# script, replacing the original header.
# Note that in most cases you should use initialize.sh instead.
