How to change the name (user that is shown on the left) that is shown in the linux terminal?

  • 772

I want to change the user that is displayed in the linux terminal. Try this command

sudo usermod -c "Nuevo-Nombre-Usuario" nombredeusuario

But it does not do it, it always continues to show me the same user in the terminal.

    Command

    sudo usermod -l NuevoNombre AntiguoNombre

    Explanation

    As the usermod documentation indicates :

    -l, --login NEW_LOGIN
    The name of the user will be changed from LOGIN to NEW_LOGIN. Nothing else is changed. In particular, the user's home directory name should probably be changed manually to reflect the new login name.

    Whose translation would be:

    -l, --login NEW_LOGIN
     El nombre del usuario se cambiará de LOGIN a NEW_LOGIN. Nada más cambia. En particular, el nombre del directorio de inicio del usuario probablemente debería cambiarse manualmente para reflejar el nuevo nombre de inicio de sesión.

    Note: You can either use sudo, or you can also login as root and run the command from there. Although it is highly recommended to log in as root , since there are processes that are executed by your user to which your terminal will show an error.

    Mistake

    actual example

    Context: I currently have a user called user , I am going to make the name change, now it will be called debian , for this, I will log in asrootand then just execute the previously explained command.

    Name change

    Note for Ubuntu

    For the case that you use Ubuntu, I would recommend that you do the following:

    1) Login to your terminal as root:

    sudo -i

    2) Change the key of root:

    passwd

    3) Log out of Ubuntu. 4) Enter a virtual terminal, executing the combination:

    Ctrl Alt F4

    5) Login as root.

    6) Run the command:

    usermod -l NuevoNombre AntiguoNombre

    7) Go back to your graphic session:

    Ctrl Alt F7

    8) Sign in.

  2. If you only want to change the name that is displayed in the console, just change the value of PS1en~/.bashrc

    [eduen@EDUENPC ~]$ cat ~/.bashrc
#
# ~/.bashrc
#
alias subl="subl3"
alias ls="ls --color=auto"
# If not running interactively, don't do anything
[[ $- != *i* ]] && return
PS1='[\u@\h \W]\$ '
    • \u = username
    • \h = pc name
    • \W = current path

    in your specific case

    PS1='[Nuevo-Nombre-Usuario@\h \W]\$ '

    Save changes and you're done.

    You can also directly change the value in console

    [eduen@EDUENPC Escritorio]$ PS1='[Prueba@\h \W]$'
[Prueba@EDUENPC Escritorio]$
