Take a look at osh (Object SHell): https://github.com/geophile/osh

It is a Python implementation of this idea: OS objects like files and processes are represented in Python. You construct pipelines as in UNIX, but passing Python objects instead of strings. E.g. to find the pids of /bin/bash commands:

    osh ps ^ select 'p: p.commandline.startswith("/bin/bash")' ^ f 'p: p.pid' $

- osh: Runs the tool, interpreting the rest of the line as an osh command.

- ^: Piping syntax.

- ps: Generate a stream of process objects, (the currently running processes).

- select: Select those processes, p, whose commandline starts with /bin/bash.

- f: Apply the function to the input stream and write function output to the output stream, (so, basically "map"). The function computes the pid of an input process.

- $ Print each item received in the input stream.

Osh also does database access (query results -> python tuples) and remote access. E.g., to get a process listing of (pid, commandline) on every node in a cluster:

    osh @clustername [ ps ^ f 'p: (p.pid, p.commandline)' ] $
