Unbecome root
 
Hi, just started with my maemo, and once I gained root access by typing "sudo gainroot" I could ls into some root folders.

My question is how do I exit the root account, become user again, I tried to exit the terminal, and restart the phone, but no luck, each time the ls command is entered on the root folders it works.

I want to be user again.

Regards
Maemon

Normally when you open the terminal you're user. Open a new terminal, issue the "whoami" command - it should give you "user".

Type Ctrl-D or "exit"+enter.

That's probably because the permissions on the directory allow it - for example:

Code:
$ ls -ld /root/
drwxr-xr-x    5 root    root            0 Aug 27 02:24 /root/
The green permission bits indicate that everyone can see the contents of the directory (r) or cd into it (x) but not write (- instead of w).

I'm not using sudo gainroot, but just root, a command that becomes available after rootsh is installed.

In that case, to become user again you just type exit and whoami shows you are user again. I just confirmed that.

Being or not being root does not restrict access to the root mountpoint of the filesystem /. The default user account can see the root mount and even create files and directories (they will be created with permissions for the user account).

As stated above, the command to see what account you are using from the terminal is 'whoami'. If it comes back as 'root' and you want to get back to 'user', simply type 'exit'.

Ok, thanks all, whoami did state off course user after restarting the xterm.

The folder I did ls on stated "permission denied" before I did sudo gainroot, now it just list files under that folder even with the user account, thats why I thought the user where always root.

its a bit strange, isn't it?

Yeah, it is expected to work as user... (user has read permissions)

Anyways, you can exit from root terminal with the 'exit' command. 'whoami' tells you what user you are at the moment.

Then when you exit, you'll be root again. The shells are nested inside each other.

You should use the following command to switch to user instead:

Code:
su - user
