Change file owner

What i did:
- logged in with acc1 and created a new user acc2
commands used: useradd and passwd.
- Then i logged in acc2. but all the files are owned by acc1.

Issue: I try to change the owner of the files using chown command . But it gives me a error message.

All i want to do is create a file in one of these folder?
Am i using the correct method??Smilie

Thanks

Where are the file the second id wants access to, and what acces does it need?

Root can chown files to anyone. You can make both same group and make group readable or even writable.

It is not wise to have mixed ownership in a subtree - only root can remove all id files and dirs unless permissions are wide open.

When i login from my id 'Ubuntu' and create a user 'johns' . The user is created.
Now when johns logins using login command, and runs 'ls -l' command, he will see that all files are owned by 'Ubuntu' and the group is Ubuntu.

If the file permission on this file needs to be changed to 777 (read, write, execute to all) How do i do it. ?

Can i change the ownership of it?? I tried
chown Johns filename
but no use?

Log in as Ubuntu and try "chown -R johns ~johns".

777 is wide open, a+rwx for command chmod

What is johns group (run 'id')?

Commands i ran:


Code:
sudo useradd johns
sudo passwd johns 
... i entered the password twice ......
sudo login johns
--- enter johns password....
whoami           ---- returns johns
 ls -l                 ----- returns  drwxr-xr-x 2 ubuntu ubuntu  80 2011-08-01 17:05 Desktop

I want to create a file in Desktop but when i enter :

Code:
echo "please help" > MyDoc
-su: cannot create MyDoc: Permission denied

OR

Code:
sudo chown johns Documents
[sudo] password for johns: 
johns is not in the sudoers file.  This incident will be reported.

Maybe sudo does not do a right useradd, as most users get a login home directory they own!

Why sudo to login as johns?

After login, are you in a johns-specific home dir?

If yes, run id to find johns' group, and use sudo to "chown -R johns <home_dir>" and "chgrp -R <group_name> <home_dir>", and you should be fine.

If no, I recommend making one, not opening up permissions to all. At most, put them in the same group and open up group permissions.

When i do useradd, it does not allow me to create the user.

PN: when the user is created it login home directory is the root
I dont understand how to go to Johns directory. Please guide me

If yes, run id to find johns' group, and use sudo to "chown -R johns <home_dir>" and "chgrp -R <group_name> <home_dir>", and you should be fine.
