Hi,
Need help to get following results from the search.  all helps will be appreciated. 

On the image below, same colors show match cases I would like to get out of my search. Here is the condition I am looking for:

Under the same pid which is all same already on image below. 

example -1 ( green on the image) :
pid_of_curl = 990820

pid_of_sh = 990821

If exe = curl and ( pid_of_curl + 1 ) has exe = sh

exe is curl and  990820 + 1 = 990821 = pid in which exe = sh

if exe is either "curl" or "wget" and its pid +1 is equal to ( bash or sh ) pid

Hey @ITWhisperer 
Thank you so much for spending time and providing this solution. 
It gives me the following output

splunkxorsplunk_0-1639983617385.png

However, I need following matches out of the data set. 
logic here is :
1. under the same ppid, (curl OR wget ) and ( bash OR sh ) should be available
2. If #1(above) is true, ((pid _of_curl + 1) OR (pid_of_wget + 1 )) = ( pid_of_sh OR pid_of_bash)

time - ppid - pid - exe
1. time2 - 981804 - 991885, 991885 - curl, bash

2. time2 -981804 - 991940, 991940 - curl, sh

Thanks again.
