I have a field in logstash ```auto [user scp -t /apps/user] ``` I would like to extract the user by doing something similar to stripping off '[' in the string. I saw that the strip option just strips off spaces. So I wanted to know if there is an option to do what I want here. Thanks. ---

You could use either a grok or dissect filter to parse that field. ---
