Why bash-4.2$?

Hi,
Thanks.

But, I don't know how to drop (or boot) to single user mode.

Kind regards

Hi,

single user mode should be runlevel 1. You can change the runlevel with the telinit command. Eg.

Code:

telinit 1

Hi,
Thanks.
The command

Code:

telinit 1

seems not to be working for me. It gives me a blank screen, I have to restart to restore the terminal interface.
What should I do?
Kind regards

Sounds like it worked. Now you should be able to unmount /home. Eg

Code:

umount /home

Then have a look in /home eg

Code:

ls -al /home

and report what you find.

Once you are done you can use telnint to go back to what ever runlevel you were at before. The command "runlevel" will list the current and previous runlevel.

Hi,
Thank you.
I got the same output as in post 14, that is

Code:

umount /home

PHP Code:



umount: /home: device is busy. 
        (In some cases useful info about processes that use 
         the device is found by lsof(8) or fuser(1))

Kind regards

Hi,

ok, so something is using /home. Try killing all user processes.
Eg

Code:

killall -u mohammed

failing that read the error message and use lsof or fuser to find what process to kill.

Well, here's the problem, if you deleted everything from /home then the files are gone, including the shell start-up scripts. You can try to use something like testdisk or photorec to recover them, but chances are good that they're gone. You should restore from back-up (you do have back-ups, right)?

WTF? How did I not see this earlier? You deleted your home directory that, is why it is not there.

Good bye,
