Description:
------------
I use shell_exec to retrieve the directory-sizes.

however the filesizes returned are exactly twice the true size.

I believe this may be related to bug #11386

Reproduce code:
---------------
// MBOX_DIR is directory of your mailboxes

echo $du_raw = shell_exec('du -d1 '.MBOX_DIR);

Expected result:
----------------
2 /usr/boxes/jeab690/mbox1
280 /usr/boxes/jeab690/mbox2
32054 /usr/boxes/jeab690/mbox3

Actual result:
--------------
4 /usr/boxes/jeab690/mbox1
560 /usr/boxes/jeab690/mbox2
64108 /usr/boxes/jeab690/mbox3

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions.  Due to the volume
of reports we can not explain in detail here why your report is not
a bug.  The support channels will be able to provide an explanation
for you.

Thank you for your interest in PHP.

No, shell_exec() returns exactly what it gets from the command, it doesn't do any magical actions like summarizing or multiplying by 2.
And no, bug #11386 is not related to your problem.
