Problems to rm one file (?--------- )

Carme Torca — Tue, 09 Jan 2007 05:16:42 GMT

Hi,

I want to rm one file, but it is not possible.

# ls -lrta
?--------- 32767 root 38680 0 Jul 15 1965 DeplMMjlhcI

When I do:
rm DeplMMjlhcI

rm: remove weird file `DeplMMjlhcI'? y
rm: cannot remove `DeplMMjlhcI': Operation not permitted

I have tried to change it with chmod, but it doesn't want.
What could I do?

Thanks a lot of!
Carmen.

Carmen,
try quoting the filename.
rm 'DeplMMjlhcI'

ls -a to check for non-printable characters in filename

rm -i and step through the files

WARNING:
This will remove all files of 0 size in directory AND SUBDIRECTORIES:
find . -size 0c -exec rm {} \;

Find the nodeid of the file and remove it that way.

Hi Carmen,

What filesystem is that file located on?
Local,nfs,cifs?

What are the permissions of the directory?

Did you try to reboot and fsck the file system (assuming it's a local file system).
Also post the output of `lsattr DeplMMjlhcI`.

Hello Carme,

there are some process using this file?
Try to remove in another run-level.

Try also to remove with an external net tool, like WinSCP3, FileZilla or with a Linux-LiveCD (like knoppix).

Hola Carmen,

That "file?" has an exorbitant link-count of 32767 it may be a directory with lots of subdirs but more probably a filesystem error.
Are there some hints in /var/log/messages?

can you do a:
# find /var -inum 229445 -exec ls -li {} \+

Finally i think the best is to get a downtime for reboot and fsck in single-user-mode.
