It's got nothing to do with IM. If you need quotes around the file
names, then you must have special characters in the file names, like
"This is the file.tiff"
Such filenames, while very normal on Windows, are very unusual on Linux
because they're a PITA.

Perhaps something in the TIFF file that IM doesn't grok. I have that
problem with some files my graphic artist creates--I've learned to just
ignore them...

I assume you're getting more than one data line out of this because you
have multiple frames.
I get one line with data followed by one blank line from identify when I
try this on various TIFF files I have. In my case, I would use
BIGGEST=$(identify -format %n $INP)
> convert "$INP"[$BIGGEST] -resize "1280x1024>" "$NEWFILE"
OK, you have a special character here, so you need the quotes around the
square brackets. Try this:
convert "$INP[$BIGGEST]" -resize "1280x1024>" $NEWFILE
Quotes ARE needed around the first argument because of the "[" and "]"
Quotes ARE needed around the resize value because of the ">"
Quotes ARE ONLY needed around $NEWFILE if it too has special characters.

Are you trying to create a variable PROBLEMATIC that has multiple
NEWFILES in them, that you want to list one at a time? For example,
would PROBLEMATIC look like
file1.tiff file2.tiff file3.tiff
To create PROBLEMATIC, use this:
PROBLEMATIC="$PROBLEMATIC $NEWFILE"
Be aware that this will actually create
" file1.tiff file2.tiff file3.tiff"
Note the leading blank? That is why I DID NOT use quotes in the
examples below. Again, know WHEN to use quote and WHEN NOT to use
quotes. You're a little quote-happy above ;)
You can write PROBLEMATIC one name per line many ways. Three examples are:
echo $PROBLEMATIC | sed "s/ /\n/g"
or
echo $PROBLEMATIC | tr " " "\n"
or
for n in $PROBLEMATIC ; do echo $n;done
I prefer the first because I'm a sed bigot. sed can do ANYTHING.
