Creating multiple users in bash shell from a csv file

Question

I'm trying to create multiple users from a csv file from a bash shell script. My csv looks like this

Codigo,Apellido,Nombre,Carrera,Facultad,Rol 
10001,Accorti,Paolo,COM,FACED,Profesor
10002,Afonso,Pedro,ICI,FIA,Estudiante
.
.
.

I have the following code

#!/bin/bash

while IFS=, read  -r Codigo Apellido Nombre Carrera Facultad Rol; 
do

password="Pass123"
sudo useradd -c "${Codigo} ${Apellido}" -d "/home/$codigo" -s /bin/bash -p "${password}"

done < Usuarios.csv 

When I run the code, I don't have any error but my terminal shows options for useradd and my accounts have not been created. This is my first time programming in bash shell, I'm not sure what I'm doing wrong.

Answer 1

Taken from the man pages for useradd:

  -p, --password PASSWORD
       The encrypted password, as returned by crypt(3). The default is to
       disable the password.

       Note: This option is not recommended because the password (or
       encrypted password) will be visible by users listing the processes.

       You should make sure the password respects the system's password
       policy.

The password when passed with -p will need to be encrypted and cannot be plain text. The alternative will be to use passwd

Another possibility would be to user newusers, although this is distribution specific.

Answer 2

I think your command for "useradd" is wrong.

#!/bin/bash

while IFS=, read  -r Codigo Apellido Nombre Carrera Facultad Rol; 
do

  password="Pass123"
  useradd -c "${Codigo} ${Apellido}" -m -p ${password} -s /bin/bash ${Codigo}

done < Usuarios.csv
