You can use Putty or Linux Terminal to SSH to your server. While there are thousands of SSH commands available and it’s hard to master all of them in a short period, mastering some SSH goodies would be a good first step to start learning SSH.

However, it’s not recommended to play around with the SSH commands you can find on the internet on your critical production server.
