Create User Accounts with Password

Below is a quick script to create a user account and password.

If no username is typed the script will exit. If the input for for the username is “Exit” or “exit” the script will exit.

When finished typing the username and password the script will show the output of the newly created user in /etc/passwd and loop back to the beginning and will ask to create another user account.

#!/bin/bash
# Script for creating user accounts

# Function Declarations
err_function() {
	echo An error has occurred!
	echo Exiting script immediately...
	exit
}

# While loop to repeat user account creation process
while true
do

# Create user account or exit the script
	echo -e "Please type new account name or type Exit to leave: \c"

# Read user Input
	read -r Username

# If account is not provided, leave script
	if [ -z "$Username" ]
	then
		echo
		echo An account name was not provided
		echo Leaving script...
		exit
	fi

# Type "Exit" or "exit" to leave script
	case "$Username" in
		Exit)
			echo Leaving script...
			exit
		;;
		exit)
			echo Leaving script...
			exit
		;;
		*)
		echo
		echo Account for "$Username" is being created...
		;;
	esac

# Create user with home directory from user Input
# Double pipes with the function are used to cleanly exit the script if an error occurs
	useradd -m -d "$Username" || err_function

# Create password for account
	echo Password "$Username" is being set...

	passwd "$Username"

# Display account record
	User_Record=$(grep "$Username" /etc/passwd)
	echo "$User_Record"
