diff

Description

The diff command mimics *nix diff output and compares two search results at a time by returning the line-by-line difference, or comparison, of the two. The two search results compared are specified by the two position values position1 and position2. These values default to 1 and 2 to compare the first two results.

By default, the text (_raw field) of the two search results is compared. Other fields can be compared by selecting another field using attribute.

Syntax

diff [position1=int] [position2=int] [attribute=string] [diffheader=bool] [context=bool] [maxlen=int]

Optional arguments

position1
Datatype: <int>
Description: Of the table of input search results, selects a specific search result to compare to position2.
Default: position1=1 and refers to the first search result.
position2
Datatype: <int>
Description: Of the table of input search results, selects a specific search result to compare to position1. This value must be greater than position1.
Default: position2=2 and refers to the second search result.
attribute
Datatype: <field>
Description: The field name to be compared between the two search results.
Default: attribute=_raw, which refers to the text of the event or result.
diffheader
Datatype: <bool>
Description: If true, show the traditional diff header, naming the "files" compared. The diff header makes the output a valid diff as would be expected by the programmer command-line patch command.
Default: diffheader=false.
context
Datatype: <bool>
Description: If true, selects context-mode diff output as opposed to the default unified diff output.
Default: context=false, or unified.
maxlen
Datatype: <int>
Description: Controls the maximum content in bytes diffed from the two events. If maxlen=0, there is no limit.
Default: maxlen=100000, which is 100KB.

Examples

Example 1:

Compare the "ip" values of the first and third search results.

... | diff pos1=1 pos2=3 attribute=ip

Example 2:

Compare the 9th search results to the 10th.

... | diff position1=9 position2=10
