Create `.gitkeep` files recursive.

git-gitkeep

#!/bin/bash

if ! git rev-parse 2> /dev/null; then
  echo -e "\033[0;31mERROR\033[0;39m: This directory is not git repository \033[0;31m:(\033[0;39m"
  exit 1
fi

Seek() {
  for DIR in * ; do
    if [ -d "${DIR}" ]; then
      if [ -f "${DIR}/.gitkeep" ]; then
        echo  ".gitkeep already exists .gitkeep in `pwd`/${DIR}"
      elif [ -z "$(ls -A ${DIR})" ]; then 
        touch ${DIR}/.gitkeep
        echo  "Create .gitkeep in `pwd`/${DIR}"
      fi
      (cd "${DIR}"; Seek;)
    fi
  done
}

Seek;
echo -e "done!! \033[0;32m:)\033[0;39m"

This works great if you're inside busybox and your find command doesn't support searching for empty directories.

Otherwise if you have a modern find command use:

find . -type d -empty -not -path "./.git/*" -exec touch {}/.gitkeep \;
