Hello,
recently I picked up knowledge of /proc/sys/vm/drop_caches
(http://lkml.org/lkml/2006/8/4/95)
It does not always work right away:
(/U is a vfat, that is, permissions are back to 755 as soon as the caches
are gone)
14:51 gwdg-wb04A:/U # chmod 644 *
14:51 gwdg-wb04A:/U # sync
14:51 gwdg-wb04A:/U # echo 2 >/proc/sys/vm/drop_caches
14:51 gwdg-wb04A:/U # l
total 50713
drwxr-xr-x 3 jengelh users 2048 2006-08-29 14:48 .
