The provided bash script is designed to check write permission for regular files only. It filters out directories and symbolic links by using the `-type f` option with find. This option ensures that only files with the regular file type are processed.

# Check if target path exists and is a directory
if [ ! -d "$target_path" ]; then
  echo "Error: Path '$target_path' does not exist or is not a directory."
  exit 1

# Check if user has sufficient permissions to read files
if [ ! -r "$target_path" ]; then
  echo "Error: Insufficient permissions to read files in '$target_path'."
  exit 1
