Probably best to use the "useradd" command.

It is difficult to post a script here, if you don't want to use "useradd", as so many people would do this in different ways.

I suspect the best thing would be do a short script to keep track of the next free UID and put that as a variable to the "useradd" command.

Hi Mahesh,

Take a look at the command useradd and userdel.

Hope it helps,

Robert-Jan.

The following script I use recently to add many users at a time:

#!/bin/sh
for i in `cat /tmp/newusers.lst`
do
USER=`echo $i | awk -F":" '{print $1}'`
UID=`echo $i | awk -F":" '{print $2}'`
GROUP=`echo $i | awk -F":" '{print $3}'`
DIR=`echo $i | awk -F":" '{print $4}'`
SHELL=`echo $i | awk -F":" '{print $5}'`
/usr/sbin/useradd -u $UID -g $GROUP -d $DIR -s $SHELL $USER
if [ $? -eq 0 ]
then
/usr/bin/passwd $USER
fi
done

#!/usr/bin/ksh
#usage :scriptname passwdfilename
set -x
for x
do
echo "enter the user name \c"
read user1
echo "the user name to be disabled is $user1"
grep "^${user1}:" $x
if [ $? -eq 0 ]
then
sed '/^'$user1':/ {

I'm attaching my version.

You'll see all kinds of cool code, some of it commented.
