Script to copy binaries including their dynamically linked libraries to a target directory, useful for creating minimal container/docker images

bundle-bin.sh

#!/bin/bash
set -euo pipefail
BIN=$1
TARGET=$2
mkdir -p "$TARGET"

bundle() {
	lib="$1"
    target="$2"

    dir=$(dirname "$lib")
    mkdir -p "$target/$dir"
	cp -a "$lib" "$target/$dir/"

    while [[ -L "$lib" ]]; do
        lib=$(readlink "$lib")
        # Prefix dir when path is relativ
        if [[ "$lib" != /* ]]; then
            lib="$dir/$lib"
        fi

        dir=$(dirname "$lib")
        mkdir -p "$target/$dir"
	   cp -a "$lib" "$target/$dir/"
