<ul data-eligibleForWebStory="true"><li>Bash scripting allows for the use of functions and the source command to create modular tools.</li><li>Functions can be used with the source command to enable modularity, especially in cybersecurity use cases like network reconnaissance and building scanner tools.</li><li>This approach eliminates the need to repeat code in every script, offering efficiency and cleaner code.</li><li>Common utility functions can be placed in a separate file, such as utils.sh, and loaded into the current shell session when running a main script.</li><li>By modularizing code in separate files, functions and variables defined there become accessible and reusable in the main script.</li><li>This design helps in avoiding repetitive logic and promotes code reusability across different scripts.</li><li>Log analysis logic becomes reusable and can be utilized for writing cron jobs or alerting systems by sourcing the necessary functions.</li><li>Using source for required functionalities in primary scripts enhances code security, testability, and scalability for various automation tasks.</li></ul>
