centos 6.4 and my bid disk mounted from EMC.

here is my directory structure.
20TB mouted from EMC
10m files -images/
500k files -txt/
wanted to get total size of images and txt folder separately.

cnt=0 > /tmp/summary_sizes.txt   # set the file to zero length while read dirname  do 
[ "$dirname" = "/data/images" ]  && continue                # skip highlevel dirs 
[ "$dirname" = "/data/txt" ]  && continue      
du -s $dirname >> /tmp/summary_sizes.txt &   # run du in the background      
cnt=$(( $cnt + 1 ))                                          # count background processes      
[  $(( $cnt % 15 )) -eq 0 ]  && wait                   # when 15 active -- wait
done  < /tmp/dir.txt

I try your script but no result
No wonder - you have skipped exactly the directories you were interested in. You should skip "/data", as HIGHERLEVEL directory, like the commentary suggested. It might help to actually try to understand what the script is doing before modifying it.

I hope this helps.
