Linux Create User Account

Q. How do I create create a new Linux user account ? How do update or modify default Linux new user information? Using the command prompt (shell) tools, how do I add a user to the system? What are command line options for adding a user?

A. To create a new user account under any Linux distribution use command called useradd. The system administrator is responsible for creating account. Login as root user (or use sudo command).

useradd command syntax

useradd [options] {username}

Depending on command line options, the useradd command will update system files (/etc/passwd and /etc/shadow file with password) and may also create the new user's home directory and copy initial files.

Linux add a new user called rakhi

Type the command as follows:
useradd rakhi
Set a password for rakhi:
passwd rakhi
Without password user account will be in locked status. To unlock the account, you need to use above passwd command. Use passwd command to assign a password and set password aging guidelines.

Set account disable date

You can set date for the account to be disabled in the format YYYY-MM-DD with -e option while creating account itself:
useradd -e {yyyy-mm-dd} {username}
useradd -e 2008-12-31 jerry

Set default password expiry

The -f {days} option set number of days after the password expires until the account is disabled. (If 0 is specified, the account is disabled immediately after the password expires. If -1 is specified, the account is not be disabled after the password expires.)
useradd -f {days} {username}
useradd -e 2009-12-31 -f 30 jerry

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

    • sashi August 26, 2011, 10:51 am

      i dont know

    • pR0Ps August 27, 2011, 5:58 pm

      cat /etc/passwd

    • manju September 22, 2011, 2:52 pm

      type in root user
      ls /home/

      • Andy October 16, 2011, 8:59 pm

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

    • Mehul January 23, 2012, 7:16 am

      with command who,,,u can see all users

      • theHOFF August 26, 2012, 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]’

    • Mustufa July 8, 2013, 7:05 am

      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…..

    • Fuji May 10, 2010, 8:35 pm

      • Sumit chadha June 8, 2011, 2:54 pm

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

        • BH.Ram Naidu June 12, 2011, 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)

          • H4CKN3T August 3, 2011, 10:12 am

            A better command to pull users would be:

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

          • T September 4, 2011, 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

        • raj April 30, 2012, 7:58 am

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

    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

    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 ???

    • Andy October 16, 2011, 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….

    Hello,

    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,

    Gal

    • wkpop93 May 9, 2011, 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

  • shreya October 6, 2009, 3:31 pm

    • Mustufa July 8, 2013, 7:10 am

      For user admin there are four commands mainly..

      1)useradd
      2)usermod
      3)userdel
      4)passwd

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

  • Girish Mahajan November 9, 2009, 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

  • Girish Mahajan November 9, 2009, 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 ! :)

    • Nilesh May 31, 2011, 12:16 pm

      Can I create user without root login ?

      • Mustufa July 8, 2013, 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:

    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.

    2.If the pirticular user forgets the password what will you do.?

    • Mustufa July 8, 2013, 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..

    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.

    • Mustufa July 8, 2013, 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 ….

      Hi..

      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

    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.
