That will only work if there is a userfolder created for every user. And thats not necessary the case.

$ who only shows you the name of the user you are currently logged into the system as. The ‘ cat /etc/passwd’ method shows all users register to the system. You can grep for userid as well which I picked up from a different post. You have to check your /etc/passwd file to see where added user id numbers start. The example i saw started at 500. Mine start 1000.

$ cat /etc/passwd | egrep ‘[1][0-9][0-9][0-9]’

Login with Any user which is Normal user not the Admin or root.
eg:[localhost@Root]#:
Root is admin and if anything in place of root will be Local user.
type:pwd
It will list the present working directory…
type cd /home.
then type ls

It will list all the users created in Home directory…..

19 BH.Ram Naidu June 12, 2011 at 6:19 pm

hi,
cut -d ” ” -f1 means d is delimiter .In this command delimiter is colon(:) .field1.If the file content is like this ramnaidu7:500:501:Bh.Ram .
After issuing above command o/p is ramnaidu7 since colon(:) is the delimiter and that is considered as field1(f1)

20 H4CKN3T August 3, 2011 at 10:12 am

A better command to pull users would be:

cat /etc/passwd | grep home | cut -d”:” -f1

Reply

21 T September 4, 2011 at 4:25 pm

I think the folliwng is important. You want one character after the -d, that being the separator between columns.

[root@localhost ~]# cat /etc/passwd | cut -d”:” -f1
cut: the delimiter must be a single character
Try `cut –help’ for more information.
[root@localhost ~]# cat /etc/passwd | cut -d: -f1
root
bin
daemon
adm
lp
sync

34 Andy October 16, 2011 at 9:01 pm

Why would give somebody root access to your machine?
Try the following

sudo -i
Enter your user password
Then when logged in as root type
passwd
to set a password for the root user.
But i don’t recommend doing this, especially because you seem not to be too fond of linux….

4)passwd

So try the options for usermod as it is used to change username which is currently active in the Linux OS

Hi Guys,
Do you want to give the root access to the normal Linux user, even after the root passwd get changed?

Do follow below commands,
Login as a root user,
Let suppose the user is imtestuser
[root@girish.mahajan ~]# useradd imtestuser
[root@girish.mahajan ~]# passwd imtestuser
[root@girish.mahajan ~]# visudo
#One file get opened,
# add the below line to the file
imtestuser ALL=(ALL) NOPASSWD: ALL
#save the file.
[root@girish.mahajan ~]# su imtestuser
[ imtestuser@girish.mahajan ~]#
[ imtestuser@girish.mahajan ~]#
[ imtestuser@girish.mahajan ~]#
[ imtestuser@girish.mahajan ~]# sudo su –
[ root@girish.mahajan ~]#

# Now even after changing the passwd , ur imtestuser get authenticated without asking for passwd, and even it get changed…


Girish Mahajan

Reply

55 Girish Mahajan November 9, 2009 at 12:00 pm

Continuing with above statements…
Smarter person can do like ,

[root@girish.mahajan ~]# adduser imtestuser –home /var/.imnotatheft/imtestuser
[root@girish.mahajan ~]# passwd imtestuser
[root@girish.mahajan ~]# visudo
#One file get opened,
# add the below line to the file
imtestuser ALL=(ALL) NOPASSWD: ALL
#save the file.
[root@girish.mahajan ~]# su imtestuser
[ imtestuser@girish.mahajan ~]# sudo su –
[ root@girish.mahajan ~]#

# Now even after changing the passwd , ur imtestuser get authenticated without asking for passwd, and even it get changed…


Now , guys , by follwing these steps , u are creating let suppose a hidden user, having a grant to logged in to as a root user without passwd and all.

Regards,
Girya ! :)

Can I create user without root login ?

Reply

57 Mustufa July 8, 2013 at 7:14 am

No you cannot create user without root Login,as Root is the Admin and only administrator has a rights to manage and create…

root is the superuser in the Linux OS.
If u try creating user with local user login
EG:[localhost@root]#->This is the root user present
If i create user
useradd a
passwd a
if you type or change user :su – 2
[localhost@a]$
Type useradd b
It wont work and will show you that u dont have superuser permission for it..

Hey,
there is also this option:

if you want to automate a scenario in which you need to define a user on a Linux machine programatically, using the above command will save you the hassle of getting prompts from the machine when defining a new user.

91 Mustufa July 8, 2013 at 8:36 am

1)If the User is not able to login though after entering password correctly,it means the user accct is locked.
The only way to unlock is using the usermod command with the Arguments and options as mentioned per the Syntx..

You can download or can know from google.com.
2)if a user can forget the password ,Root user can go and reset it,else the user can also change the passwd but then he has to enter password with password complexity.ie. number,symbol and text…
Root can changed without complexity..
Choice is yours,Any issue kindly email me,will help you..

You can go and install after creating a partition so as to make Two different OS.
You should have min of 4 GB Ram and min of 512 HDD…
But it will boot Linux first as it will be installed after preinstalled windows..
So you can do this way by reading the docs from google ,i just provided you the idea..

My opinion is to installed Linux virtually by the means of VMWARE workstation as it wont occupy space on ur physical HDD.
I have installed the same as mentioned Virtualy.

To see all the user accounts on your system;
– First switch to a root user by issuing the command # su –
– A password for root is required to switch.
– Once successfully switched, use the command # cat /etc/passwd
– All the user accounts will be listed including parameters except their password.
