Description: Libraries in Bash scripts are collections of functions that can be reused across different scripts, facilitating modularity and code organization. These libraries allow developers to group related functions, which not only improves code readability but also reduces redundancy by avoiding the need to rewrite the same code in multiple places. By using libraries, programmers can easily share and maintain code, which is especially useful in larger or collaborative projects. Additionally, libraries can include functions for common tasks such as string manipulation, file management, and network operations, allowing users to focus on the central logic of their scripts without worrying about the implementation details of each function. In summary, Bash script libraries are essential tools that optimize the development and management of scripts, promoting good programming practices and efficiency in development workflows.
