  grep -nHP ' $' $filename
done <<< "$(find /PATH/TO/DIRECTORY -type f -exec grep -lIm 1 -P ' $' {} \;)"


# for ~/.bashrc | ~/.zshrc | ~/.bash_profile | whatever your environment uses
findTrailingSpaces()
{ 
  [ "$1" == "" ] && >&2 echo please provide path to directory && return;
  [ ! -d "$1" ] && >&2 echo \"$1\" is not a directory && return;
  
  while read filename
