Title: Re: Passing Return-Delimited Text to UNIX
Sort
AT FIRST, IT THOUGHT:
The additional wrinkle that was needed was that I needed to
delimit with the linefeed to run the shell script, but then I needed
to get the text items of the returned text from the script delimited
with a return, or else I'd only get a one-item list.
set my text item delimiters to ASCII character 10
set vBookChapterNameText to
(text
items
of
vBookChapterNameList) as string
set my text item delimiters to
return --needed to reconvert to list; otherwise
it's truncated.
set
vSortedNameList to text items of
(do shell
script "echo "
& quoted form of vBookChapterNameText & " | sort")
set my text item delimiters to
{""}
set vChosen to choose from list vSortedNameList with prompt
"Open one or more chapters from THOM." with multiple selections allowed
BUT THEN I SAW:
... that if I added without
altering line endings to the do shell script command that that
wasn't necessary.
Two lessons learned.

For instance, if I have compiled an

lines separated by a return, how can I pass that to the UNIX sort
command?

Hey Rick,
The shell doesn't do returns. It understands linefeeds (Unix),
so you need to delimit with linefeeds in the first place or pipe
through 'tr'.
set AppleScript's text item delimiters to
return
set _var to quoted form of
(characters of "zyx" as text)
do shell script "echo "
& _var & " | tr '\\r' '\\n' | sort"
If you haven't already it's a good idea
