View Full Version : [ubuntu] du -s not working.
July 29th, 2008, 03:53 AM
So I'm new to Ubuntu. You've probably gathered that by my being on this particular forum, though, so I'll skip the pre information. All that I really need to say is that I've been using this guide to learn how to use the shell/terminal in Ubuntu. In the guide, I'm currently learning how to create a simple shell script that will allow me to output my system information in an HTML file. However, there's a part in it that wants to show the information in my home directory. The command that was given in the guide was
du -s /home/* | sort -nr
However, anything with
in it returns this error:
du: cannot read directory `./.dbus': Permission denied
So, does anyone know how to solve this? Thanks!

sudo du -s

I'm guessing that you have a directory called .dbus in your home directory that you do not have read permission on (you probably created it accidently)
and see if there is a directory named .dbus listed.

I've tried running it with sudo, when I do that, it just tells me the same thing, but, instead of it being ./.dbus that it can't access, it's ./.gvfs.
I've tried running it as root with the
command. But even that doesn't work. When listed with ls -l, both of these files come up, and the owners are root.

I've actually had the same problem before, and root couldn't even delete the .gvfs directory.
It was strange, and I don't remember what I did to resolve it...at least you can rest assured you're not crazy.

Hah, well, that's good. It's not like it's crippling, but it's strange.
(Fun fact: my first thought when this happened was "virus." Then, I remember I wasn't on windows. :P )

Using sudo, try opening up the permissions on .dbus. For example the following command will give the user, group, and other read-write-execute permission:
sudo chmod 777 .dbus
Then when you run du -s as, you should not get a permission error.

yeah, me with the same problems.
Logged in as root, I can read the .dbus directory. But not the .gvfs
Its the gnome virtual file system. And it shows owner as "??"
What does this mean ? I've not seen this before.

thanks, cheetaux, that allowed me to access ./.dbus. After I changed permissions in that, it told me that I couldn't acces dbus_sessions, a subdirectory of ./.dbus. I changed permissions in THAT, and now I can run du -s! Thanks for that. I had previously tried changing permissiosn, but I did so in Nautilus instead of the terminal, which didn't work for some reason.
However, and this is what I think is strange, I can du -s as a user, but when I try to sudo it, it gives me the .gvfs message! When I try to change permissions on THAT, the access is denied.
