but the terminator can be changed using the |
48 |
|
.I \-t |

option. |
50 |
+ |
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. |

Note that there is no space between this option and its argument, and |
57 |

certain arguments, such as a space or a tab, must be quoted or escaped |

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

|
An output is either a file or a command. |
62 |
|
If an output file exists, it will not be overwritten unless the |
65 |
|
.I \-a |
66 |
|
option. |
67 |
|
Commands are given in quotes, and begin with an exclamantion point ('!'). |
68 |
+ |
A period ('.') may also be specified as output, |
69 |
+ |
which indicates that no output is desired for this field. |
70 |
+ |
The corresponding data will be skipped on the input. |

A hyphen ('-') by itself can be used to indicate the standard |
109 |
|
output, and may appear multiple times. |
110 |
+ |
The options before the first appearance determine the |
111 |

header parameters, if any. |
112 |
|
Results will be unpredictable if the standard output is specified |
113 |
|
in this way |
114 |
|
and any of the command outputs also writes to their standard output. |
