Creating user in UNIX and cloning the user

Add group to the user with -a (append to the group list)

sudo usermod -a -G vboxsf harvey

To close the user create a script like this

harvey@hvb:~/hscripts$ vi clone-user.sh

#!/bin/bash

SRC=$1

DEST=$2
BLANK=" "

SRC_GROUPS=$(id -Gn ${SRC} | sed "s/${SRC}${BLANK} //g" | sed "s/ ${SRC}//g" | sed "s/ /,/g")

SRC_SHELL=$(awk -F : -v name=${SRC} '(name == $1) { print $7 }' /etc/passwd)

useradd --groups ${SRC_GROUPS} --shell ${SRC_SHELL} --create-home ${DEST}

passwd ${DEST}

run it to clone 

Syntax 

sudo ./clone-user.sh source_user target_user

It will ask the password for the new user

sudo ./clone-user.sh harvey michael

Done!!!
