Hello,

I have a script that does some imageMagick stuff in a for-loop and save 
the results in sub-directories. Normally it works perfect, but in a 
certain condition it produces a strange result I cannot explain.

I start the script in my /home/daniel/digikam folder with ./scriptname.sh

It cd's to the directory containing the files that should be transformed 
and the for-loop searches for all *.png files, like:

cd to png-directory
for bild in *.png
do
  resize $bild, add text, save ${bild%.png}.jpg as JPEG-image in 
sub-directory ./4000
  add color profile to ./4000/"${bild%.png}.jpg"
done

(The original script resizes to 2 sizes into 2 sub-directories, adds a 
color-profile and then converts to new color-profile to both versions,
it is here: https://www.daniel-bauer.com/div/strange_script.txt)

Now when I have NO png-files (but jpg-files) in the "png-directory", in 
my opinion the script should do just nothing, because there is nothing 
to process in the for-loop.

But what happens is:

All files that already have been in the sub-directories before are 
copied to a file with the name of the last file that already was in that 
sub-directory, plus a number.

[to explain:

there are already 3 files A.jpg, B.jpg, C.jpg in the sub-directory 
before I start the script.
After the script executed I have there addditional:
C-0.jpg, C-1.jpg, C-3.jpg ... ... C-32.jpg ... ...
where those C-n-files are copies of A, B and C.jpg

]

Where is my error?
Why does the script do anything, when the condition for the for-loop 
isn't met (there are no *.png-files to process)?

Thanks for your help!

Daniel
