In this project, you need to onboard 20 new Linux users onto a server. Create a shell script that reads a csv file that contains the first name of the users to be onboarded.
-
Create the project folder called Shell
mkdir Shell -
Move into the Shell folder
cd Shell -
Create a csv file name names.csv
touch names.csv -
Open the names.csv file
vim names.csv -
Insert some random names into it. (One name per line)
The script you created should read the CSV file, create each user on the server, and add to an existing group called developers (You will need to manually create this group ahead).
touch onboarding_users
chmod +x onboarding_users
Ensure that your script will first check for the existence of the user on the system, before it will attempt to create that it.
cd /etc
getent group developers
``
// url of ifs
PS: Anytime a new user is created, examples.desktop get populated in the /etc/skel/ directory. Put your variables in quotes if there is a tendency for linux to expand it.
Ensure that the user that is being created also has a default home folder
Ensure that each user has a .ssh folder within its HOME folder. If it does not exist, then create it.
For each user’s SSH configuration, create an authorized_keys file and add ensxure it has the public key of your current user.
- remove the user if error
sudo userdel -r <username>
Before Deploying your script, you will need to update your current user with the correct public key and private key.
In your current home directory change directo .ssh folder
cd .ssh
create a file for the public key
touch id_rsa.pub
open the file using your favorite editor and paste in the public key
vi id_rsa.pub
create a file for your private key
touch id_rsa
open the file using your favorite editor and paste in the private key.
vi id_rsa
