The folder structure is: /home/bobuser/ftp/files
I am logged in as root, and have taken ownership of /bobuser
, /ftp
and /files
. I have 777 permissions on all folders. There is nothing inside /files
.
When I'm inside /files
and do ls -a
I get
. ..
When I do
lsof +D /home/bobuser/ftp/files
I get this:
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
bash 1479 root cwd DIR 253,1 4096 256003 /home/bobuser/ftp/files
lsof 2080 root cwd DIR 253,1 4096 256003 /home/bobuser/ftp/files
lsof 2081 root cwd DIR 253,1 4096 256003 /home/bobuser/ftp/files
If I try to kill service 2080 or 2081 (kill -9 2081
) it tells me service doesn't exist. Those two PID numbers change every time I run the same command. If I kill 1479 it kills my SSH session as user and I'm logged out.
In fact I want to delete /bobuser
and everything below.
EDIT:
More output as requested by comments:
Logged in with root user and changed directory to root, even though I was there already.
root@myhost:~# cd /root
Running this next line returns nothing. I only get a response if I'm cd'ed into the files directory, then I get the output as posted above.
root@myhost:~# lsof +D /home/bobuser/ftp/files
Tried this line next and return is 0
root@myhost:~# ls -l /home/bobuser/ftp/files
total 0

Short answer:
If you take a look at the FD section of
lsof
man page, you will find out thatcwd
means current working directory.The other thing you mentioned is different PIDs for 2nd and 3rd lines. Those are the PIDs of
lsof
command, so every time you runlsof
, it will run with a new PID and then it will be closed.After changing your directory to
/root
, we can see that there is no open file under/home/uerbob/ftp/files
directory, so my first guess is that some partition is mounted there.You should run below command to see if any partitions are mounted there:
If yes, you will get an output like this:
Then simply unmount the partition and remove the directory.
