pies

The name Pies (pronounced "p-yes") stands for Program Invocation and Execution Supervisor. This utility starts and controls execution of external programs, called components. Each component is a stand-alone program, which is executed in the foreground. Upon startup, pies reads the list of components from its configuration file, starts them, and remains in the background, controlling their execution. If any of the components terminates, the default action of Pies is to restart it. However, it can also be programmed to perform a variety of another actions such as, e.g., sending mail notifications to the system administrator, invoking another external program, etc.

    Pies can be used for a wide variety of tasks.  Its most obious use
    is to put in backgound a program which normally cannot detach itself
    from the controlling terminal, such as, e.g., minicom.  It can
    launch and control components of some complex system, such as
    Jabberd or MeTA1 (and it offers much more control over them than the
    native utilities).  Finally, it can replace the inetd utility!
