   # Loop through the list of users and change passwords
   for user in "${users[@]}"
       echo "Changing password for user: $user"
       sudo passwd $user

In the users array, replace "user1", "user2", "user3", etc., with the actual usernames for which you want to change passwords. You can add as many usernames as needed.

You’ll be prompted to enter the root password (or use sudo if required) to run the script with administrative privileges.

  1. The script will loop through the list of users and prompt you to enter new passwords for each user. Follow the prompts and enter the desired passwords. The script will change the passwords for all the specified users.

By using this script, you can easily change passwords for multiple users in one go. Remember to use it responsibly and protect the script file with appropriate permissions, as it has administrative privileges.
