Latest version of Curves.sh not generating output file

[jmo]

Hello,

I am working on Ubuntu 14_04_03 with ImageMagick 6.7.7-10 trying to call the following command:
./curves.sh "98,98 80,80" input.jpeg output.jpeg

Output.jpeg is never created and the script finishes with no error at all. It seems the latest update from April 2015 causes the problem, if I am right.
All the other scripts are working perfectly. Only the curves one is not working.

Has everybody else encountered this problem? Can you reproduce it? Or have you found a solution to make the script work?
Can someone help? I absolutely need the curves script working... and I have no older working version available...

Do you have a solution or in the worst case an older version that you could post here?

Thanks in advance!

Best regards,
jmo

I have fixed the script. Download the latest from my web site

I have taken the new script and it is working now after a first test. Thanks!
