Question

I have seen a lot of answers about this subject but I don\'t want to do this using find. I have written this but something not working:

function Cou

If your goal is to count directories, there are so many options.

The find way, which you said you don't want:

CountDir() {
  if [[ ! -d "$1" ]]; then
    echo "ERROR: $1 is not a directory." >&2
    return 1
  fi
  printf "Total: %d\n" $(find "$1" -depth 1 -type d | wc -l)
}

The for way, similar to your example:

CountDir() {
  if [[ ! -d "$1" ]]; then
    echo "ERROR: $1 is not a directory." >&2
    return 1
  fi
  count=0
  for dir in "$1"/*; do
    if [[ -d "$dir" ]]; then
      ((count++))
    fi
  done
  echo "Total: $count"
}

The set way, which skips the loop entirely.

CountDir() {
  if [[ ! -d "$1" ]]; then
    echo "ERROR: $1 is not a directory." >&2
    return 1
  fi
  set -- "$1"/*/
  echo "Total: $#"
}
