Yes, Luke was just point out that -m is not available on BSD. But, you probably do have: du --help You should check from your prompt on shell world, but I suspect you can just do: du -s and get a result in kilobytes. The -m just gives the result in megabytes.. But, having also myself just looked at du --help, I can now ammend something else I just said a minute ago. Instead of subtracting a total for mail, do: du -s -x mail/ to exclude the mail directory from the calculations. So, get anything better with these commands?
