Hey Rick,

Using without altering line endings is very handy at times, but there is a pitfall:

set AppleScript's text item delimiters to return

set _var to quoted form of (characters of "zyx" as text)

set _sorted to paragraphs of (do shell script "echo " & _var & " | tr '\\r' '\\n' | sort" without altering line endings)

choose from list _sorted

You end up with a trailing linefeed, and this will produce an extra list item if you coerce to list.

Paragraphs is happy with either CRs or LFs of course, and on occasion it can be more convenient than fooling with TIDs.

You also know that when you get text back from a Unix command and use WALE that you'll have that last linefeed, so you can allow for it and use items 1 thru -2 of (paragraphs of <text>) if that makes more sense in your context.

So there's more than one way to do it.

Best Regards,

Chris
