Check out Object Shell: http://geophile.com/osh http://geophile.com/osh. It takes the idea of commands and pipes, but is oriented around python objects. Usable from the command line, and also has a python API. It includes integration with the OS (e.g. commands to get files and processes as python objects), databases, remote nodes, and combinations of these, (E.g. submit a query to all nodes in a cluster, pull back the results and integrate them.) I developed and used this tool while developing a sharded system running on a cluster of nodes with postgres running on each. Object Shell is GPL. See the page above for examples, documentation and downloads.
