Add shell bundler

[eonist]

Yes, there are several tools designed to bundle multiple .sh files into a single shell script. Here are the main options:

Dedicated Bundlers

• bash-bundler / bashpack - Tools that combine multiple shell scripts into one, resolving source statements and inlining the referenced files
• awk/sed concatenation - Simple approach where you concatenate files and strip duplicate shebangs

Common Approaches

1. Using source at runtime - The traditional method is to use source or . to include other scripts, but this requires all files to be present at runtime[3]

2. Manual concatenation with preprocessing - You can write a simple build script that:

   • Reads your main script
   • Finds source statements
   • Replaces them with the actual file contents
   • Outputs a single combined file

3. SHC (Shell Compiler) - This compiles shell scripts into binaries rather than combining them into one .sh file, so it's not exactly what you're looking for[6]

Simple DIY Solution

A basic approach is to create a build script like this:

#!/bin/bash
# build.sh
cat lib/*.sh main.sh > dist/combined.sh
chmod +x dist/combined.sh

For more sophisticated needs where you want to resolve source statements automatically, tools like bashcompile or writing a custom preprocessor script that inlines sourced files is the typical solution. The shell scripting ecosystem doesn't have a standardized "bundler" like JavaScript has with webpack, so many developers create project-specific build scripts for this purpose.[5]
