It doesn't work without quoting here!

Thanks, at the moment I am unsure what could happen. It are so different files 
(not from me).

I have problems with Tiff-files, which create the warning:
unknown field with tag 317 (0x13d) encountered. `TIFFReadDirectory'

I tried to specify the biggest file with

BIGGEST=`identify -format "%w %n\n" "$INP" | \
sort -g | tail -1 | cut -f 2 -d" "`

convert "$INP"[$BIGGEST] -resize "1280x1024>" "$NEWFILE"

But the biggest file was not chosen always. So I make a warning list at the 
end, which can be corrected manually. The user has to check this problem 
himself.

I create a variable
PROBLEMATIC="$PROBLEMATIC""$NEWFILE""  |  "

How can I create an output, which lists every file in a new line?
