6.  Now recheck the passwd, shadow and group files that contain ‘root2’ user informations to confirm the changes:

 

[root@fedora ~]# less /etc/passwd

root:x:0:0:root:/root:/bin/bash

root2:x:0:0::/home/root2:/bin/bash

 

[root@fedora ~]# less /etc/shadow

root:$1$B2BRWv4X$Gb.MPc6I3RwCkEkT13ow21:13080:0:99999:7:::

root2:$1$bQHGH4cX$TtsV/WVdFe5cIsHWjzc.N1:13112:0:99999:7:::

 

[root@fedora ~]# less /etc/group

root:x:0:root,root2

bin:x:1:root,bin,daemon,root2

daemon:x:2:root,bin,daemon,root2

sys:x:3:root,bin,adm,root2

adm:x:4:root,adm,daemon,root2

disk:x:6:root,root2

7.  Everything should be ok, now try to login to system with newly created ‘root2’ account, see example:

Could not chdir to home directory /home/root2: No such file or directory

-bash-3.00#

-bash-3.00#

-bash-3.00# su –

[root@fedora ~]#

 

8.  Make sure that you execute the su command with hyphen ( su - ) to get the PATH of the user that you become to... below is the example of the su command with hyphen and without hyphen.

 

Loggin in as user tenouk, then execute $PATH as example below.

 

[tenouk@fedora ~]$ $PATH

-bash: /usr/lib/qt-3.3/bin:/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/home/ tenouk/bin: No such file or directory

[tenouk@tenouk ~]$

 

Use the su command to change to root user as example below and then execute $PATH as example below.

 

[tenouk@fedora ~]$ su root

Password:

[root@fedora tenouk]# $PATH

bash: /usr/kerberos/sbin:/usr/lib/qt-3.3/bin:/usr/kerberos/bin:/usr/local/bin:/b in:/usr/bin:/home/tenouk/bin: No such file or directory

[root@fedora tenouk]#

 

Then try use the su - command and verify with the $PATH as example below.

 

[root@tenouk tenouk]# su - root
