imageMagick convert from a folder to another command in Linux?

Question

I have the two folders under the same level directory folder1 and folder 2 now I try to convert all images in folder1 to folder2 and with same file name. here is what i have now:

 for f in folder1/*.jpg
 do 
       convert $f  -resize 80%X80% +profile "*" -quality 85 folder2/$f
 done

and it throws the following message from each file it tried to convert: convert: unable to open image `folder1/folder2/st-3474827-1.jpg': No such file or directory @ blob.c/OpenBlob/2440.

and I know its directory problem but google for two days already still dont know how to fix it. Can you help me with this?

Answer 1

There's two ways you could deal with it.

1. Use mogrify:

   mogrify -path folder2 -thumbnail 50x50 folder1/*.jpg
   

2. Use basename:

   for filename in folder1/*.jpg; do
       basename="$(basename "$filename" .jpg)"
       convert "folder1/$basename.jpg" -thumbnail 50x50 "folder2/$basename.jpg"
   done
   

The former option is probably better, but the latter may be clearer.
