What is the primary function of the "nl" command in Splunk?

The primary function of the "nl" command in Splunk is to assign a unique line number to each event in the search results. This command is particularly useful when dealing with large datasets, as it provides a simple way to reference individual events based on their position in the result set. By adding a line number, users can easily identify and sort through events, making it easier to analyze specific occurrences within their data.

The "nl" command is not intended for calculating totals, filtering events, or displaying data graphically, which distinguishes it from the other options. Instead, the command focuses on organizing and labeling the events, enhancing the user’s ability to work with the data in a structured manner.
