Code:

find $path -type f -name "*$exten" |
 while read iFile
 do
    echo $iFile
    iFile1=${path1%/}/${iFile##*/}
    echo $iFile1
    destFile="${dest%/}/${iFile##*/}"
   lipo -create "$iFile" "$iFile1" -output "$destFile" # changed the last line
 done

I figured out the problem in my script ,
It generated this path
"/sw/lib/ImageMagick-6.5.4/modules-Q16/codersycbcr.a"
which should have been
"/sw/lib/ImageMagick-6.5.4/modules-Q16/coders/ycbcr.a"

Thank you very much. I normally feed exten wildcards "*.a" or "*.dylib". I need to make checks for file existence.

I have faced that problem too. How should I handle white spaces in file paths?
