Creating new users using a text file as imput (using only shell script and/or awk)
I need somebody who could help with an exercise.
You have a text file called users.txt with this info inside:
users.txt:
The script should create an user using the first word of each line, the second word of each line will be used as password, and the third one as the home directory.
I would be very grateful If anybody can point me in the right direction

virt-login-shell
VIRT-LOGIN-SHELL(1) Virtualization Support VIRT-LOGIN-SHELL(1)NAME
virt-login-shell - tool to execute a shell within a container matching the users name
SYNOPSIS
virt-login-shell
DESCRIPTION
The virt-login-shell program is a setuid shell that is used to join an LXC container that matches the user's name. If the container is not
running, virt-login-shell will attempt to start the container. virt-sandbox-shell is not allowed to be run by root. Normal users will get
added to a container that matches their username, if it exists, and they are configured in /etc/libvirt/virt-login-shell.conf.
The basic structure of most virt-login-shell usage is:
virt-login-shell
OPTIONS -h, --help
Display command line help usage then exit.
-V, --version
Display version information then exit.
CONFIG
By default, virt-login-shell will execute the /bin/sh program for the user. You can modify this behaviour by defining the shell variable
in /etc/libvirt/virt-login-shell.conf.
eg. shell = [ "/bin/ksh", "--login"]
By default no users are allowed to use virt-login-shell, if you want to allow certain users to use virt-login-shell, you need to modify the
allowed_users variable in /etc/libvirt/virt-login-shell.conf.
eg. allowed_users = [ "tom", "dick", "harry" ]
