I am new in the Commutiy and new in the topic GROK.
I have a message where I want to replace a certain string. The problem the string contains the GROK meta character ^.
The whole thing is supposed to happen in an ingest pipeline in the ES cluster.
Here is an example:
This should become
cat /etc/passwd | grep "Thomas"
So the ^@ should be replaced by a space.
I have no idea how to do this.
Thanks for your time and help
