Unknown directory

TWBSupport — Fri, 04 Aug 2006 14:09:09 GMT

With some issues that I was having earlier and are now fixed, I found some odd issues on my system that I want to resolve, do some housecleaning, if you will.

I have a 'ghost' directory off root.
dr-xr-xr-x 28 bin bin 8192 Apr 1 2003 var
drwxrwxrwx 2 root sys 96 Apr 25 2003

The bottom one is what I am talking about. How can I investigate what this is, it doesn't have a name. I'm sure it's nothing, but I want it off the server.

run

ls -b

to see the non-printable characters in the file/directory names.

thank you!

\177\177\177\177

How do I get into it? I can't cd into it.

Try doing an 'ls -labi'.

That will list everything, include its inode number at the beginning of the line and if there are any non-printable characters in the dirctory name, it will print the octal value of those characters.

Based on that you could then do a

# find . -inum |xargs ll

to make sure you just get the one directory. And then to delete it:

# find . -inum | xargs rm

(Where is the inode number returned from the above ls command.)

ll -b or ll | vis

should show you want character are the directory name. so you can see whats in there or delete it.

You can also do "ls -il" to find out the inode of the directory. Then use find to rename it to something else so you can more easily investigate what's inside before taking further action:

find . -prune -inum X -exec mv {} newname \;

cd /
ls -i # this will list the inodes; find the one associated with your bogus directory
let's say it is inode 1234

next,
find . -xdev -type d -inum 1234 -exec rmdir {} \;

I would first use a safe command such as "-exec ls -l {} \;" to make sure your find filter is just right.

Hi Denda:

It would appear that the directory beneath '/var' has a name with unprintable characters. Do:

# ls -il /var

This will give you the inode number of the directory in question as the left-most field. Now do:

# find /var -xdev -inum -exec rm -ri {} \;

...where is the inode (number) determined from the 'ls'.

Too, this will require you do answer "y" to remove any files under the directory and/or the directory itself.

'man ascii' shows \177 is a delete character, so try "cd "

Hmmm.. Here's the output

Shouldn't the inode only be associated with the one directory?
Thanks for your help.

Inode numbers are unique to each FILESYSTEM.

If you ran your find from the / (root) directory then you will find all occurrences of inode 2305 among ALL filesystems on your machine.

Re: Unknown directory

Jonathan Fife — Fri, 04 Aug 2006 14:47:50 GMT

You need to add an -xdev to the find command, or it will search all filesystems from the directory specified (in your case, the root dir) and not just the one specified.

In any case, from the last bit of output it appears that directory is empty and you can use one of the rm commands above.

Re: Unknown directory

James R. Ferguson — Fri, 04 Aug 2006 14:48:21 GMT

Hi Denda:

Using the inode number you determined to match your directory, you need to do:

# find / -xdev -inum -exec rm -ri {} \;

That is, your directory is "off root" as you say, just like '/var' is "off root".

You *must* use '-xdev' as I show(ed) since you do *not* want to cross mountpoints. Inodes are only unique within filesystems, so you must be very careful to select exactly what you want!

Good gracious.. What am I typing wrong? I wanted to take Clay's advice and make sure the filter is correct, but I get the following error.

find / -xdev -inum 2305 -exec ls -l {}\;
find: -exec not terminated with ';'

Thank you all for your patience.

Re: Unknown directory

A. Clay Stephenson — Fri, 04 Aug 2006 15:06:37 GMT

The between {}\; is all important. Bear in mind that when you do an ls of a directory, you will also see any files under that directory.
