The trepctl version command outputs the version number of the specified replicator service.
trepctl versionTungsten Replicator 6.1.1 build 129
The system can also be used to obtain remote version:
trepctl -host host2 versionTungsten Replicator 6.1.1 build 129
Version numbers consist of two parts, the main version number which denotes the product release, and the build number. Updates and fixes to a version may use updated build numbers as part of the same product release.
