extract username for element in path

[kritho]

Hi,
Im new to regexes, and I'm trying to get the username field configuration to my extract-fields

source:
/u01/somedir/somedir/user1/anotherfile
/u01/somedir/somedir/user3/anotherfile2
/u01/somedir/somedir/user4/anotherfile3

I want to get the "user1|2|3" part to a username field.

Any tips?

To do that inline in the search, you can use rex in the example below, look at the fourth element of the path (i.e. source);

your search | rex field=source "/([^/]+/){3}(?<username>[^/]+)"
