uniq

uniq

Synopsis

Filters out repeated adjacent results.

Syntax

uniq

Description

The uniq command works as a filter on the search results that you pass into it. It removes any search result if it is an exact duplicate with the previous result. This command does not take any arguments.

Examples

Example 1: Keep only unique results from all web traffic in the past hour.

eventtype=webtraffic earliest=-1h@s | uniq

Note: If you have a large dataset, it's more efficient to use the dedup command on the _raw field in place of uniq:

... | dedup _raw

"If you have a large dataset, it's a better practice to use the dedup command on the _raw field in place of uniq: "

Why? What does "better" mean? More efficient? More reliable? Why ever use "uniq" instead of "dedup _raw"?
