Abstract: Methods, apparatus, computer program products for exchange data among air-gapped devices are provided. The method comprises: identifying, by a device in a cluster of devices, a plurality of accessible devices in the cluster via corresponding respective quick response (QR) codes; generating, by the device, logical routing information based on the identified plurality of accessible devices, the logical routing information comprising at least identifiers of the identified plurality of accessible devices; and transmitting, by the device, data encoded in a plurality of QR codes to a destination device in the cluster based on a shortest routing path identified in the logical routing information.

Abstract: Provided herein are a method, system, and computer program product for creating scripts from command line history. The method includes determining a plurality of distances among a plurality of commands from a command line history. A plurality of command sets is determined from the plurality of commands based on the plurality of distances among the plurality of commands. Each of the plurality of command sets includes at least two neighboring commands. A script is created by the one or more processors based on a first command set and a second command set of the plurality of command sets in response to a distance between the first command set and the second command set being less than a predetermined threshold.
