Thread: User account creation shell script

Im new to scripting what i want to do is create 20 user accounts. I want the user account to be ex. user1 ..... user20. but the password can be auto generated; also for each user account created i want to send a text file to /home/admin/useraccounts folder with each username and password for each user ; separate text file for each user.

Code:

#!/bin/bash

mkdir -p /home/admin/useraccounts
for (( i=0; i<=20; i++ ))
do
useradd user$i
< /dev/urandom tr -dc A-Na-n1-9_ | head -c8 > /tmp/passwd.txt
cat /tmp/passwd.txt | passwd --stdin user$i
echo -e "Username:user$i" > /home/admin/useraccounts/user$i
echo -e "password:" >> /home/admin/useraccounts/user$i
cat /tmp/passwd.txt >> /home/admin/useraccounts/user$i
done
rm -rf /tmp/passwd.txt

Note:When password generating i just created a password which will not contain o(small ooo), O(capital OO), 0(zero). This is to remove confusions for users.. some times user will get confusion when using these characters

that worked perfectly. Thanks now i will need to understand the code...any book you recommend for shell scripting?
