[Gllug] bash string confusion

[Craig Millar]

Am trying to write a small bash script to check which stock items in our
inventory have not yet been illustrated. So, I get a dump of stock numbers
out of the database (filemaker - won't get started on that) and compare them
to the numbered images in the folder. Only, it is not working and I am
absolutely stumped:

for i in `cat photo.txt`; do
    if test ! -e "$IMAGEDIR/$i.jpg" ; then
        echo $i >> unillustrated.txt
    fi
done

It returns all the records. As I know there are several thousand photographs
in the image folder, this is definitely not correct.

So, I echo the resultant test using

 j="$i.jpg"; echo $j

in the for loop and too my utmost surprise it is returning the image names
with the .jpg suffix at the beginning, for example: .jpg0

If I pipe the output to less, I get something sort of resembling what I am
after, for eg: 59034^M.jpg - whither the ^M? Have opened up the file in vi -
sometimes filemaker throughs up all sorts of strange characters - can't see
any strange line breaks or the file though - certainly no ^Ms when i tried to
remove them.

Please somebody tell me where I am going wrong - googled to no effect and
it's driving me mad. Have tried a zillion string combinations and I'm sure
I'm just being lame.

Thanks!
Craig
