Updating a value in a lookup

Hello,

I have a lookup called top sites with the bellow:

 

Name

Ip address

test1

10.10.10.10

test2

10.10.10.11

Test3

10.10.10.12

Test4

10.10.10.11

Test5

10.10.10.11

 

I am trying to update test3 IP address with the bellow:

 

| inputlookup topsites.csv | append [
|eval Name=Test3
|eval Ip address="9.9.9.9"] [|stats count by Name,Ip address]
| outputlookup
createinapp=true
topsites.csv

 

However it just adds another entry instead pf replacing the IP address value, what am I missing?

 

Thanks

From your original post, it looks like the field is called 'ip address' - if this is not the case, then use the real field name instead of 'ip address'

Try something like this:

| inputlookup topsites.csv
| eval 'Ip address'=if(Name="Test3","9.9.9.9",'Ip address')
| outputlookup
createinapp=true
topsites.csv

Good Morning,

 

Thanks for your reply,

 

when I run the search it adds another column with the updated value called 'Ip address' instead of updating the existing field value, is there a way around this?

 

Thanks

 

Joe
