Thank you for your post.
This is not a stupid question. This has already been reported for FileMaker Pro on Mac. The line endings are Macintosh line endings, and even the Mac Unix Terminal cannot see the end of the line.
The current workaround is execute the following perl command:
perl -i -pe 's/\015/\012/g' filename.txt
This will convert the Mac line endings to Unix.
Thank you, TSGal!
