i am first time use linux, How can i see all user ??


2 sashi August 26, 2011 at 10:51 am

i dont know


3 pR0Ps August 27, 2011 at 5:58 pm

cat /etc/passwd


4 manju September 22, 2011 at 2:52 pm

type in root user
ls /home/


5 Andy October 16, 2011 at 8:59 pm

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


6 Mehul January 23, 2012 at 7:16 am

with command who,,,u can see all users


7 theHOFF August 26, 2012 at 8:51 pm

$ 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]’


8 Huskies xD February 23, 2014 at 7:30 pm

Nice regEx :)


9 Mustufa July 8, 2013 at 8:47 am

No only the user who is active or logged In….


10 lan October 14, 2013 at 6:19 am

type ‘w’ command.


11 Luca Francesca November 6, 2012 at 12:44 pm

User and their home

cat /etc/passwd | awk -F: ‘{print $1,” =>”, $6}


12 John Bryan February 12, 2013 at 1:18 am

you don’t need cat.

awk -F : ‘{print $1}’ /etc/passwd


13 Luca Francesca February 12, 2013 at 2:23 pm



14 hariprasad March 26, 2013 at 8:46 am

cat /etc/passwd
vim /etc/passwd


15 Mustufa July 8, 2013 at 7:05 am

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

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

Sagar: cat /etc/passwd


17 Fuji May 10, 2010 at 8:35 pm

cat /etc/passwd | cut -d”:” -f1


18 Sumit chadha June 8, 2011 at 2:54 pm

@Fuji : hi , cat /etc/passwd | cut -d”:” -f1 , what is the meaning of this command.Pleaswe tell ASAP.


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

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


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


22 raj April 30, 2012 at 7:58 am

It display the passwd file in /etc/ and after cut command using -d-delimiter
where u specify field1 it will shows..

30 mehdi May 31, 2009 at 9:27 am

i cant create password for my user
errore: dab password: it is based on a directory word.


31 Vishal June 2, 2009 at 5:06 am

It was a really simple & useful tutorial.
@Mehdi: Try something difficult;t as your password. Linux is intelligent enough to disallow simple dictionary word as password.
Say for example you can try: awk007


32 Amit December 19, 2010 at 3:03 pm

login with root account and then change password.


33 satyn June 16, 2009 at 7:37 am

i just laod ubuntu and there is no option for PW during the installation now somw want to access my machine through SSH and asking for root PW how can i create the pw for root as well as other account and pw , please guide me ???


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
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….

Is it possible to create a new user by edit the /etc/passwd file ?
when i try to add a new line with a new user name, user ID , user comment, home directory
it doesn’t work.
What am i missing ?

Thank you all,



44 wkpop93 May 9, 2011 at 2:26 pm

No, you cannot create a new user by editing the /etc/passwd. Instead you should either use a GUI to help you or use ‘useradd -p


45 shreya October 6, 2009 at 3:31 pm

how can i add a user without using useradd command in linux?


46 Mustufa July 8, 2013 at 7:07 am

Through graphic mode you can add,like in windows.
like as User friendly screen will be pulled up and you can create within the screen only…


47 wolful October 18, 2009 at 2:03 pm

how to create linux:/home/admin ,
or how to rename user “wolful” in “admin” without the reinstallation of the linux(suse) ??


48 Amit December 19, 2010 at 3:06 pm

use usermod command


49 Mustufa July 8, 2013 at 7:10 am

For user admin there are four commands mainly..


So try the options for usermod as it is used to change username which is currently active in the Linux OS
Try to find it from Internet and it will surely help…u

54 Girish Mahajan November 9, 2009 at 11:53 am

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


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.

Girya ! :)


56 Nilesh May 31, 2011 at 12:16 pm

Can I create user without root login ?


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
Type useradd b
It wont work and will show you that u dont have superuser permission for it..

61 Tomer January 26, 2010 at 11:58 pm

there is also this option:

adduser tomer -p Liux12345

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.



62 Justin March 10, 2010 at 8:07 pm

how to create multiuser in linux?


76 sam August 2, 2011 at 4:50 pm

is already multiuser by default


77 Mustufa July 8, 2013 at 7:19 am

No such command exist where you can create multiple users unlike multiple files in Linux OS.

It requires advance Shell scripting…

sudo chmod 777 -R
#with absolute path

i have some questions..Please answer it…
1.How to know the pirticular user password is locked.?
2.If the pirticular user forgets the password what will you do.?


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..


92 deepak March 24, 2012 at 6:32 pm

When I type the command useradd it gives the following details please provide the solution
deepak@deepak ~/Desktop $ useradd ram
Command ‘useradd’ is available in ‘/usr/sbin/useradd’
The command could not be located because ‘/usr/sbin’ is not included in the PATH environment variable.
This is most likely caused by the lack of administrative priviledges associated with your user account.
useradd: command not found

hey, i want to install linux in my system but i am having windows-7.i want to operate linux from cd or from usb.which way would be better.please tell me.


99 Mustufa July 8, 2013 at 8:27 am

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.

Hi everyone, i am trying to add a user in ” /home/ ” but every time i get this error

command ‘useradd’ is available in ‘/usr/sbin/useradd’
the command could not be located because ‘/usr/sbin’ is not included in the PATH environment variable.
This is most likely caused by the lack of administrative privileges associated with your user account.
useradd: command not found.

what should i do..??
i use the syntax : “useradd desd”.

I also tried sudo before the command but it wont accept the password ….


107 Mustufa July 8, 2013 at 8:31 am


you should try creating user in superuser mode..as Root is the ony user having sufficient priviledges for creation and deletion of users….

You must be creating under local user login..
try creating under Root user,it will work…

If you want a simple solution, you can use bash for this (This will vary for users of unity/gnome/kde). Use ‘zenity’ (see $zenity –help)

$ export credentials=$(zenity –password –username)
$ echo $credentials

113 Embony March 30, 2014 at 12:41 pm

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.
