The less command handles large files efficiently by loading only the portions of the file that you are currently viewing, rather than loading the entire file into memory. This makes it particularly useful for very large files, such as logs or configuration files, as it reduces resource usage and allows for quicker access to the content.
When you navigate through the file using less, it fetches and displays only the necessary data for the current view, allowing you to scroll through the file page by page without overwhelming your terminal or consuming excessive memory. This approach makes less an ideal tool for examining large text files in a Linux environment.
