command to check if a field is binary

does splunk have a command that can check to see if a field is binary or has binary characters in it?

Can you be more specific?

It sounds like you need a regular expression. The only binary characters are "0" and "1".

This regex would match binary characters: "[01]+"

Hey @jowenssi.... to be specific I was curious if there is a Splunk command, that when passed an argument to it, it would check if there are any binary characters in it. For example, we are presently looking for any malformed file names.

I did find this article (using regular expressions) to help me with what I was looking for. Thank you for your answer.
