What is the role of a command like 'cd' in command line interfaces?

The command 'cd', which stands for "change directory," is specifically designed to manage files and directories within command line interfaces. Its primary function is to navigate between different directories in a file system. By using 'cd', users can move into a specified directory or back to a previous location. This tool is essential for organizing and accessing files efficiently within a hierarchical file structure.

When working in a command line environment, managing the location within the directory structure is crucial for executing various file-related tasks, such as opening files, executing scripts, or moving files. Thus, the ability to change directories directly influences how users interact with the file system and maintain an organized workspace.
