Hi

I am trying to use cmd batch file to list the size of all directories
in my roaming user profile - so I an clean it out.

DU.exe works well and gives me the exact output I want - the sum of
the size of the files in each directory EXCLUDING subdirectories. e.g.

P:\MyPrograms\EDITORS\Scite>du -Ssb %CD%
2641767 P:\MyPrograms\EDITORS\Scite

P:\MyPrograms\EDITORS\Scite\tools>du -Ssb %CD%
8834439 P:\MyPrograms\EDITORS\Scite\tools

I would use a for loop to iterate over all the directories, but
testing with a single directory shows this command to be painfully
slow.
(dir /AD /B /S %USERPROFILE%)

Is there any way to optimize the DU function or an alternative you can
suggest that gives the identical output.

I did read the link below - but the output is not what I wanted.

Kind Regards

Gavin

Given that you have 'du.exe' from Cygwin (so that you have the
latest gear), I'd go with a combination of 'find' to get directory names
and 'du' to print the sizes; I'd also use --threshold=SIZE to exclude
directories smaller than SIZE:

  $ find . -depth -type d -exec du -hxSt 10M '{}' +

or with a pipe:
  $ find . -depth -type d -print0 | du --files0-from=- -hxS --threshold=10M

Finally, as you asked for Windows, I want to mention a very useful
graphical tool: "windirstat".

As this is more a question how to use du(1) - and not a bug - I'm
marking this issue as such in our bug tracker.

Have a nice day,
Berny
