Lebesgue Utility (LBG Utility) or Lebesgue Command Line Interface (LBG CLI) is a command-line interactive tool for resource management, job management, project monitoring, and other functions.

This article introduces the invocation method of Lebesgue Utility 1.x version. Compared with versions below 1.0, the new version has the following improvements:

  • More complete documentation, all instructions can be added with -h to view usage instructions;

  • Improve the API call part, the API part is separately named lbgcore, allowing developers to call it themselves;

  • Table output supports multiple formats such as table, yaml, json, and csv;
