An automation script is a set of commands or instructions that performs tasks automatically without manual effort. It helps save time, reduce errors, and improve consistency.
Automation scripts can create servers, deploy applications, configure systems, run tests, or monitor resources. They are commonly written in Shell (Bash), Python, or PowerShell and are used with tools like Jenkins, Ansible, and Terraform.
In simple words, an automation script does repetitive tasks automatically, making IT operations faster, easier, and more reliable.
