| |
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 . drwxr-xr-x 22 root root 4096 2006-08-25 14:00 .. drw-r--r-- 2 jengelh users 2048 2006-08-29 13:55 as -rw-r--r-- 1 jengelh users 13806629 2006-08-29 14:00 all-20060611.tar.bz2 -rw-r--r-- 1 jengelh users 37816633 2006-07-28 19:25 inkscape-0.44-2.guru.suse101.i686.rpm -rw-r--r-- 1 jengelh users 297243 2006-08-15 01:13 vmware-any-any-update104.tar.gz
Remains 644.
