How to display a custom field with underscore from search result

For instance, how to show "_msg" from the search result? Thanks.

| makeresults
| eval _msg="Hello World"

You can rename the field to not start with an underscore, and then Splunk will display it:

| makeresults
| eval _msg="Hello World"
| rename "_msg" AS "msg"

If you have many fields that start with underscores, you could do this:

| makeresults
| eval _msg="Hello World"
| rename "_*" AS "*"

Note that this will also display and convert other internal fields, like _time.

If you are wondering why you need to rename them at all, it's because Splunk uses underscores to identify internal fields:
