Which command is used in Splunk to remove duplicate entries from search results?

  1. remove

  2. unique

  3. deduplicate

  4. dedup

The correct answer is: dedup

The command used in Splunk to remove duplicate entries from search results is "dedup." This command is designed specifically to eliminate duplicate results based on one or more fields specified by the user. When you apply the dedup command, it retains the first occurrence of each unique value for the specified field(s) and removes subsequent occurrences, allowing for a cleaner and more concise set of search results. Using dedup is particularly useful when you want to aggregate information or focus on distinct values within your dataset without unnecessary repetition. For instance, if you are analyzing log files and want to see a list of unique users who have accessed a system, dedup can simplify your results significantly. Other choices, such as "remove," "unique," and "deduplicate," are not actual commands in Splunk and do not perform the action of removing duplicates from search results. This reinforces why "dedup" is the correct answer in this context.
