Might it be the case that du follows links into other file-systems and includes the size of their contents?

The -x switch is supposed to make it not do that.

-x, --one-file-system
skip directories on different file systems

Maybe that's not operational here, where du is just a symlink to busybox. But it claims to support the switch:

~ $ du --help
BusyBox v1.10.2 (Debian 3:1.10.2.legal-1osso26+0m5) multi-call binary

Usage: du [-aHLdclsxhmk] [FILE]...

Maybe you should show step by step what is the problem? According to your previous message package was properly uninstalled.

I think he's just asking for you to explain what your problem is, slowly and thoroughly, one step at a time.

If you read the posts above, it's been said a couple of times that the dpkg output you posted looks normal. i.e. the "problem" is not visible.

I've completed the list of non-opt usage in the first post. Hope it's useful for some

Maybe I can help you guys here. If you are receiving this information when using dpkg then mplayer is removed from your system. That first field that says "RC" means that the package was removed, but configuration files left.

If dpkg --purge was used to remove the package, or the package was never installed, then the first two letters would be "un". If the package is installed, you would see "ii".

Another, more english way to view this, is using:

Code:
~$ dpkg --status xserver-xephyr
Package: xserver-xephyr
Status: unknown ok not-installed
Priority: optional
Section: x11
Pay attention to the status line... "not-installed". Evidently I don't have xserver-xephyr installed on my desktop. So those of you that are thinking mplayer did not remove from your system.. please try this command, or verify that your -l command says "rc" or "un". Either of these will indicated that yes, it has been removed.

I changed your script, so that the line
$du = `du -s /$_`;
now is
$du = `du -xs /$_`;

But it looks like "du" still follows the links. I tried in on mc which I manually moved away from rootfs. Although I'm not sure what your script does at that point of time - or in which directory "du" thinks it is.

Sorry, but I don't know perl - the only thing is that I heard people say it is a write only language (no read ).

So, does anyone now, how to modify that script to don't follow symbolic links?

"du" does NOT follow symbolic links, i just tested it.

btw, -P is the du-switch to deactivate symlinks, but it's not present on the tablet, and it's supposed to be default anyways.

what makes you say that du follows links? any hard evidence?

I didn't actually test this before posting the script, because I assumed du behaviour would be normal (i.e. don't follow symlinks) but here's a quick test which seems to show it is normal:

~# mkdir ttt
~# ln -s /usr/share ttt/test
~# ln -s /usr/share test2
~# du -s /usr/share
76716 /usr/share
~# du -s ttt test2 /usr/share
0 ttt
0 test2
76716 /usr/share
~#
the -x switch is not relevant to symlinks in particular. It's to tell du not to look at disk usage on separate filesystems which are mounted under the directory it's looking at.

So

du -s /

would give the disk usage for everything under / including /home and /home/user/MyDocs, which are separate filesystems, but

du -sx /

would only give the disk usage for the filesystem that / was part of.

Or, to give another example:

# du -s /home
2195060 /home
~# du -sx /home
204468 /home
The first result is bigger because it's counting /home/user/MyDocs. The second result doesn't look at that, because it's a separate mount to /home, and the -x switch has been given.

So in short the script shouldn't need any change to do the Right Thing in relation to symlinks

Edit: Nope, it did the Wrong Thing in relation to symlinked directories. Please get the new version (from the original place) if you're having trouble with that.
