ls - List directory contents cd - Change directory grep - Search text using patterns chmod - Change file permissions ssh - Secure shell for remote login
Windows Commands:
[cmd]
dir – List directory contents
cd – Change directory
ipconfig – Display network configuration
netstat – Display network connections
tasklist – List running processes
[/cmd]
For further reading on Terraform and IaC, visit the official Terraform documentation and HashiCorp Learn. These resources provide comprehensive guides and tutorials to deepen your understanding of Terraform and its applications in cloud infrastructure management.
By combining the knowledge from the study guide with hands-on practice using the commands and codes provided, you can significantly enhance your skills in Terraform and infrastructure management. This will not only prepare you for the certification but also make you proficient in real-world scenarios.
