Supposing you only want to supply one directory at a time to du, here's a cheesy way around it:

Save the script below it to a file named, say "sdu", and supply it a directory like so:

$ sdu ./foo3 1 bar 0 bazz 18 test Total: 19

Here's the shell script: #!/bin/ksh typeset -i total du -ask `ls -a $1 | egrep -v '^(.|..|.snapshot)$'` | while read line do echo $line set $line usage=$1 ((total=$total+$1)) done echo "Total: $total"

Hi all,

I have a few directories that are automounted from NetApp F720 Filer to the SUN boxes. The mounted directories are directories under qtrees. .snapshot is accessible under all mountpoints. The issue I have is when doing du to query the directory usage, there will be error messages due to permission level of contents beneath the .snapshot.

I would like to get the correct disk usage of my mounted directories. One way to do it is to disable access to the snapshot directories by "vol options volumename nosnapdir on". Is there anyway of getting the correct output of du without accessing the .snapshot directories and not having to turn off and on the options each time, perhaps the right options of du to bypass that particular directories?

Thanks for any input. Nic
