Hi, first post, so hello to all.
I have a Bash scripting problem that is driving me a bit nutty.

It involves a program called 'convert' which is part of the ImageMagick collection.
Normal usage from the commandline is:

$ convert -resize 120x120 inputfile.jpg outputfile.jpg

This is working just fine (from the command line)


However while inside a shellscript everything seems to go weird, this I beleive should work...

echo converting thumbnails
for searchfile in ./*.jpg
do
echo processing
echo $searchfile
convert ‐resize 120x120 "$searchfile" "$tndir/$searchfile"
done

but I get instead

convert: Unable to open file (‐resize) [No such file or directory].
convert: Unable to open file (120x120) [No such file or directory].

I have tried strong quotes to bind the arguments tighter

convert '‐resize 120x120' "$searchfile" "$tndir/$searchfile"

I have tried opening it in a subshell

(convert ‐resize 120x120 "$searchfile" "$tndir/$searchfile")

But nothing will convince it that -resize 120x120 is an argument not a file!!!

The file arguments themselves are fine $searchdir and $tndir are interpreted right. Indeed I get unaltered files dumped in the destination directory which kind of confirms that its just the -resize flag that isn't getting heard.
I have read the man for this program over many times and I'm sure i'm using it correctly.

Any ideas on how to crack this? Many thanks to any takers.
