Copy only certain Zend Framework libs and their dependencies into a specified directory

copy_zf_files.sh

#!/bin/bash
#
# Copy only certain Zend Framework libs and their dependencies into a specified directory.
#
# This script was created because copying the entire Zend Framework into an existing project
# is not really necessary if you only want to use part of it. However you fall into dependency
# hell because most sub-libraries use multi-purpose libs like Zend_Exception and Zend_Validate.
#
# Put this script in a fresh copy of ZF's `library` folder and run it as follows:
#
# USAGE:
#     ./copy_zf_files.sh Zend/Barcode <DESTINATION FOLDER>
#
lib=$1
dest=$2

for pattern in $(grep -Ehor "Zend_[A-Za-z0-9]+" $lib | sort | uniq | sed 's=_=/=') Zend/Loader; do
  if [[ -d $pattern || -f $pattern.php ]]; then
    ls -1d $pattern* | xargs -J % cp -rp % $dest
