I should have added the following that was run on the same machine: /dev/hdc1 230G 207G 12G 95% /home/data/m [root@www music]# ls -Rl|wc -l 8768 [root@www music]# date > /tmp/du.txt; du -h >> /tmp/du.txt; date >> /tmp/du.txt Took < 1 second. So. You might want to count your number of files. You could write a script that uses tree -dfi and du --max-depth=0. I'm not sure this would be any faster though. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
