A Command Prompt developer works with the Command Prompt interface, a text-based user interface used to execute commands in Windows OS. They write scripts, automate tasks, troubleshoot issues, and manage system files. They use languages like Batch or PowerShell for scripting. Tasks include creating and managing directories, managing system processes, configuring network settings, and interacting with the OS kernel. They also use Command Prompt for debugging and testing software. They need to understand system architecture, file structures, and command syntax. Often, they have a background in system administration, scripting, or software development.
