disk usage

graziano

Hello,

I written a simple php script to calcolate disk usage
on a directory ($name) using the linux command du ,

<?
ob_start();
passthru("/usr/bin/du -sk /home/$user/$name");
$spacea = ob_get_contents();
ob_end_clean();
$spaceb = ereg_replace ("/home/$user", "", $spacea);
$spaceb = str_replace(' ','',$spaceb);
$spacec = $spaceb/1024;
$spaced = number_format($spacec, 3, ',', ' ');
?>

Unluckly sometime if some directory contains "restrictive" permission or chOwn it could returns some error lines like these

/usr/bin/du: cannot change to directory /home/test/catalogs/test/session/Z': Permission denied

Is there any way to delete this error output ?

Thanks

If you put @ just in front of the function that generates the error, then it should not output it to the screen.

Or you can set the error reporting level to E_NONE.
But that's not advised for developping :rolleyes:

Unluckly I place a @ before passthru , but I am still receiving the
error ...It seems that @ doesn't work with passthru ...

<?
ob_start();
@passthru("/usr/bin/du -sk /home/$user/$name");
$spacea = ob_get_contents();
ob_end_clean();
$spaceb = ereg_replace ("/home/$user", "", $spacea);
$spaceb = str_replace(' ','',$spaceb);
$spacec = $spaceb/1024;
$spaced = number_format($spacec, 3, ',', ' ');
?>
