Add a New User to the System

This script can be used to automate the process of adding a user via the command line.
This script has been modified for Solaris 8 but can be modified to fit individual needs very easily.

First create the file newuser:

# cd /sbin
# touch newuser

Add the following information to the newuser file: [download newuser]

# Add a new user to the system
# Modified script found at

thiscmd=`basename $0`
thisuser=`/usr/xpg4/bin/id -u`

# first things first - are we root?
case $thisuser in
0 ) ;; # root - fine
* ) echo "You must be root to run $thiscmd" && exit 1

if [ "$#" -ne 1 ]; then
echo "USAGE: $thiscmd username" && exit 1

# does username already exist?
grep ˆ$1: /etc/passwd > /dev/null 2>&1
if [ "$?" -eq 0 ]; then
echo "User $1 already exists. Please re-run with a different username!"
exit 1
echo "Adding New User [$1] to `hostname`"
# Assumptions
# -----------
# By default, we know that "useradd" will assign the next available UID
# Also, under SuSE, the "users" group is GID 100

echo "Please enter the users real name: "
read real_name
echo "Please enter the users Group: "
read group_name
echo "Please enter the users ID: "
read user_id
echo "Please select a login shell (enter for /bin/sh): "
read u_shell
if [ "$u_shell" = "" ]; then
# No shell entered - default to /bin/sh
echo "Using /bin/sh"
grep $u_shell /etc/shells > /dev/null 2>&1
if [ "$?" -eq 0 ]; then
echo "Using shell $u_shell"
echo "Shell $u_shell not found in /etc/shells"
echo "Defaulting to /bin/sh"

echo -e "\n\n"
echo "About to add user with the following details:"
echo "User name: $1"
echo "Real name: $real_name"
echo "Shell: $def_shell"
echo "Home Directory: /users/$1"
echo "User ID: $user_id"
echo "User Group: $group_name"
echo "Type [y] to confirm, or anything else to quit"
read response
case $response in
[yY]* ) ;; # fine
* ) echo "Aborting user creation process"
exit 1 ;;

# Add the user proper!
echo "\n\nAdding user $1 [$real_name] to system - DO NOT ABORT NOW!!"
useradd -g $group_name -u $user_id -d /users/$1 -s $def_shell -c "$real_name" $1
cp -r /etc/skel /users/$1
chown -R $1:$group_name /users/$1

echo "User $1 successfully added to system!"
echo "User $1 [$real_name]: added to `hostname` on `date`" >> /var/log/newusers
