If I understand you, you're using "tail -c 2 | head -c 1" to separate the number of
lines from the whitespace in the "wc -l" output. In fact it appears to extract just
the last digit. You could use "awk '{print $1}'" to print the number on its own.

I think you would want to round up nnumber to avoid one processor running two xargs
processes:
nnumber=`expr \( $files + $cpu - 1 \) / $cpu`
