First create a file which contains all the user name. Something like this:

nurealam
nayeem
mrahman
farid
rubi
sankar

Save the file as userlist.txt.
Now create the following bash file:

#!/bin/sh
for i in `more userlist.txt `
do
echo $i
adduser $i
doneSave the file and exit.

chmod 755 userlist.txt

Now run the file:

./userlist.txt

This will add all the users to the system. Now we have to change the passwords. Let’s say we want username123 as password. So for user nayeem the password will be nayeem123, rubi123 for user rubi and so on.

Create another bash file as follows:

#!/bin/sh
for i in `more userlist.txt `
do
echo $i
echo $i”123″ | passwd –-stdin “$i”
echo; echo “User $username’s password changed!”
done

Run the file.
All the passwords are changed.

# Make that them there directory.

If you need to make sure a script is run as root, add the following to the start of the script:

if [[ $UID -ne 0 ]]; then
echo “$0 must be run as root”
exit 1
fi

#!/bin/bash

users=`cat /etc/passwd`
for i in $users ; do
user=”"
dir=”"

user=`echo $i | cut -f1 -d: | awk ‘{print $1}’`
dir=`echo $i | cut -f6 -d: | awk ‘{print $1}’`

check=`expr substr “$dir” 0 14`

# if [[ $check == "/home/mailuser" && -d $dir ]] ; then
echo $user
chown -R $user /home/mailuser/$user
# fi
done

[root@home ~]# find /etc -type f -exec grep -Hil sonny {} \;
/etc/shadow
/etc/group
/etc/passwd-
/etc/shadow-
/etc/gshadow
/etc/passwd

This script is used to make onboard nic eth0 and addon gig card eth1

If allowed to boot w/o this; it boots PCI slots before onboard…
