Built-in Commands
Built-in commands are pre-defined functions or utilities integrated directly into an operating system shell, programming language interpreter, or software environment, providing essential operations without requiring external programs or installations. They enable core tasks like file management, process control, and system configuration, often optimized for performance and reliability. Examples include commands like 'cd' in Unix shells or 'print()' in Python.
Developers should learn built-in commands to efficiently interact with systems and tools, as they are fundamental for scripting, automation, and debugging in environments like Bash, PowerShell, or programming languages. They are crucial for tasks such as navigating file systems, managing processes, and performing basic operations without external dependencies, enhancing productivity and portability across different setups.
