Creating a new field depending on wildcard search

[ajdyer2000]

Hi I know this is probably an easy one but I'm new and need some help.

I have the following Field Called "Account Name"

Account Name                                  

Alan Test Account                             

Debbie Production Account         

John Dev Account                            

Ed Test Account                                 

I would like to create a new field called Environment that matches Test, Production ,Dev

Account Name                                  Environment

Alan Test Account                             Test

Debbie Production Account         Production

John Dev Account                            Dev

Ed Test Account                                 Test

One possible approach:

<your search>
| rex field='Account Name' "\S+\s(?<Environment>\S+)\sAccount"

[VatsalJagani]

You can validate that you are extracting the environment field from all the results with the below query:

<your search>
| rex field='Account Name' "\S+\s(?<Environment>\S+)\sAccount"
| search NOT Environment=*
| table "Account Name"

If you see any results that mean those account names are differently formatted than what you provided examples here.

If you have "No results" in this search you are good to go. You can use the solution provided by @PickleRick .
