Maybe some of the techniques used could be transposed in your context. files=`find . -name '*.tif' -print | wc -l | tail -c 2 | head -c 1` cpu=`grep processor /proc/cpuinfo | wc -l | tail -c 2 | head -c 1` nnumber=`expr $files / $cpu` find . -name '*.tif' -print | sed -e 's/ /\\ /g' | sed -e 's/(/\\(/g' | sed -e 's/)/\\)/g' | xargs -P $cpu -n $nnumber mogrify -format png
