LR_DEANONYMIZE.IN(1)

NAME
lr_deanonymize - restore anonymized data, using a dump as produced by lr_anonymize(1)

SYNOPSIS
lr_deanonymize dumpfilestem

DESCRIPTION
lr_deanonymize reads a file containing anonymized emailaddresses, ipnumbers, and hostnames (typically a report, generated from a logfile from an internet service) from stdin, and prints a "deanonymized" version of this file to stdout. It reads its information to do this from a bunch of Berkeley DB's, stored in files whose's names are derived from dumpfilestem, as produced by lr_anonymize(1).

EXAMPLE
A 'logfile' like e.g.
