[source:://e:\trs\log\accountweb\aw*.log]
TRANSFORMS-anonymize = ssn-anonymizer, ssnlookup-anonymizer

Transforms.conf:
[ssn-anonymizer]
REGEX = (?m)(^|)SSN=($|['])[0-9]{9}($|['])
FORMAT = $1SSN=#########'$2
DEST_KEY = _raw
[ssnlookup-anonymizer]
REGEX = (?m)(^|)SSNLookup=($|['])[0-9]{9}($|['])

This:

[source:://e:\trs\log\accountweb\aw*.log]
SEDCMD-SSN = s/SSN=\d{9})/SSN=xxxxxxxxx\1/g

Should be this:

[source:://e:\trs\log\accountweb\aw*.log]
SEDCMD-SSN = s/SSN=\d{9}/SSN=xxxxxxxxx/g
