How do I add to an Ubuntu system many users at once?

Hi @erel,

You can create a list of users and passwords and then use a small bash script to go through them.

Let’s assume the list looks like this:

# File named studentusers
user1-password1
user2-password2
user3-password3

Your bash script will look like:

#!/bin/bash
# Run script with SUDO
for user in $(cat /root/studentusers); do
  STUDENT=$(echo $user | awk -F"-" '{print $1}')
  STUDENT_PASSWORD=$(echo $user | awk -F"-" '{print $2}')
  useradd $STUDENT
  echo "${STUDENT}:${STUDENT_PASSWORD}" | chpasswd
done

To create the script, ssh to your Droplet, create a file called createusers.sh and put the above contents in it. Additionally, don’t forget to create the studentusers file in your /root directory.

Once that is done, just execute the following sudo bash createusers.sh

That should do the trick.
