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 |
53 |
|
additional |
54 |
|
.I \-t |
55 |
|
options between each output specification. |
56 |
< |
Note that there is no space between this option and its argument. |
57 |
< |
If no character is specified, the default (newline) is used. |

If no argument is given, the default newline terminator is re-established. |

An output is either a file or a command. |

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

Output is either to a file, to a command, to the standard output, or to discard. |

If a named output file exists, it will not be overwritten unless the |
63 |
|
.I \-f |
64 |
|
option is given, or it is being appended using the |
65 |
|
.I \-a |
66 |

option. |
67 |
+ |
The same output file may not appear more than once. |
68 |
|
Commands are given in quotes, and begin with an exclamantion point ('!'). |
69 |

At most, one command may reliably write to its standard output, and |
70 |
+ |
doing so is incompatible with |
71 |
+ |
.I rsplit |
72 |
+ |
also writing to standard output. |
73 |
+ |
A hyphen ('-') by itself tells |
74 |
+ |
.I rsplit |
75 |
+ |
to write directly to its standard output, and may appear multiple times. |
76 |
+ |
The options before the first appearance determine the |
77 |
+ |
standard output header parameters. |
78 |
+ |
A period ('.') tells |
79 |
+ |
.I rsplit |
80 |
+ |
to discard the corresponding data, and also may appear multiple times. |

|
If the terminating character is set to something other than newline ('\\n'), |
108 |
|
a newline is added after each record (in addition to the terminator). |
109 |
|
For binary output formts, no number implies one value per output. |
110 |
< |
The terminator is not used for binary output streams. |

No terminator characters are expected or written for binary outputs. |
