Do not run in the background. Useful for debugging.
-l argument
Set the object load behavior, as follows:
  • 0 — load directory names and objects on demand. Default.
  • 1 — load all directory and object names on startup, but do not load object contents. Load object contents on demand.
  • 2 — load directories, objects, and object contents on startup.
-m mount
Specify the mountpath for PPS. Default is /pps/
-p path
Set the path for backing up the persistent storage.
-t period
Specify the periodicity of the forced persistence, in milliseconds. For example -t 5000 forces the PPS service to write to persistent storage every five seconds. Default is no forced persistence.
Enable verbose mode. Increase the number of "v"s to increase verbosity.


The pps program manages the Persistent Publish/Subscribe system, which provides a simple method of disseminating information to interested processes.
