If a space is specified as the terminator, then fields are separated by |
| 51 |

any number of white spaces, including tabs, returns, and newlines. |
| 52 |

Different terminators may be given for different fields by specifying |

additional |

options between each output specification. |

If a named output file exists, it will not be overwritten unless the |

The same output file may not appear more than once. |

Commands are given in quotes, and begin with an exclamantion point ('!'). |

At most, one command may reliably write to its standard output, and |

doing so is incompatible with |

A hyphen ('-') by itself tells |

.I rsplit |

The options before the first appearance determine the |

standard output header parameters. |

A period ('.') tells |

.I rsplit |

to discard the corresponding data, and also may appear multiple times. |
