# Class Netchannels.input_command

    class input_command : string -> in_obj_channel

Runs the command with `/bin/sh`, and reads the data the command prints to stdout.

The method `pos_in` returns the number of read octets.

When `close_in` is invoked, the subprocess is `wait`ed for. If the process exits with code 0, the method returns normally. Otherwise, the exception `Command_failure` is raised.
