options do not require a count, as this will be determined by the |

The |

.I \-p |
74 |

option specifies "passive mode," where characters that do not |
75 |
+ |
match the input format are passed unaltered to the output. |
76 |

This option has no effect unless |
77 |

.I \-i |

is also specified, and does not make much sense unless |

.I \-o |

is also given. |

With both input and output formats, the passive mode can |

or stream without affecting the rest of the data. |
