alternatively, combine symlink checking in 'find', liberating 2
checks from the while loop/if condition.  this could have been
further modified to remove the "file readable" test,  but i 
preferred to be notified about non-text/unreadable files.


find <directory> \( -type f -a ! -type l \) |
while read Old
do
  # this needs to be more sophisticated; but something is better than
  # nothing
  #
  if ( ! file "$Old" | grep 'text' >/dev/null 2>&1 ) \
     || [ ! -r "$Old" ]
  then
    echo '* '  $Old 'may not be a text file or not readable; skipping...'
    continue
  fi

  echo ' --  sanitizing ' $Old

  tr -d '\r' < "$Old" > "${Old}.changed"

  # optionally remove old files, keep only changed ones
  #
  #mv -f "${Old}.changed" "$Old"

done
