nbd-trdump1

Usage

Overview

nbd-trdump translates a transaction log produced by nbd-server (specifically by the transactionlog configuration directive) into human readable form.

The command acts as a traditional UNIX filter, i.e. the transaction log must be supplied on standard input, and the human readable output is sent to standard output.
