两种方法的区别在于如何设置字段分隔符。
The difference between these two methods has to do with how we set the field separator.
默认的字段分隔符是制表符。
除非您指定了一个不同的字段分隔符,否则将使用空格或制表符分隔字段。
Unless you specify a different field separator, fields are delimited by blanks or tabs.
一般而言,最好在脚本内部设置字段分隔符,因为这样可以少输入一个命令行参数。
It's generally best to set the field separator inside the script itself, simply because it means you have one less command line argument to remember to type.
对于ASCII文件,您可以指定文件的字段分隔符、转义字符、是否应包括尾随空白,以及文件的编码。
For ASCII files, you can specify the field delimiter for the file, as well as the escape character, whether trailing blanks should be included, and the encoding for the file.
在该脚本中,(通过设置FS变量)在代码中指定字段分隔符,而前一示例通过在命令行向awk传递- F “: ”选项来设置FS。
In this script, the field separator is specified within the code itself (by setting the FS variable), while our previous example set FS by passing the -f ":" option to awk on the command line.
货币分隔符包括千位分隔符、小数点、小数位置、字段长度和填充字符。
Currency separators include the thousands separators, decimal separators, decimal position, field length, and padding character.
为了确保能识别出选择列表,您必须将一个分隔符(这个分隔符依次由一个空格,一个句点和两个空格组成):". "添加到分隔符字段。
To make sure that the selection lists are recognized, you must add the delimiter of a space, followed by a period, followed by two spaces: " . " to the delimeter field.
创建CSV文件需要定义要使用的分隔符(逗号[,])和要引用的字段;我选择引用所有非数值字段。
Creating the CSV files requires defining which delimiter to use (a comma [,]), and which fields to quote; I opted to quote all non-numeric fields.
注意:这个字段以逗号作为分隔符。
本例中的FormatType是delimited格式,数据文件中的字段由分隔符“|”(管道)分开。
Format Type in this example is Delimited, as the fields in the data file are separated by a delimiter "|" (pipe).
每条Order记录都由使用逗号分隔的字段组成,因此该分组被定义为Explicit——Delimited并且分隔符的值为“,”。
Each Order record consists of fields separated by commas, so this group is defined as Explicit — Delimited and the delimiter value is ", ". Each record is terminated by newline character.
对于多值字段来说,要设置multivalue="true",并使用mveditseparator和mvdisplayseparator指定值的分隔符。
For multi-value fields, set multivalue="true" and specify the value delimiter with mveditseparator and mvdisplayseparator.
此处理程序使用mqheader格式字段,如果将其设置为MQXML,则会将消息正文视为XML,否则会将消息正文视为带分隔符的数据。
This handler USES the MQHeader format field and if it is set to MQXML the message body is treated as XML, otherwise the body will be treated as delimited data.
可以看到这个文件使用冒号(:)作为分隔符,每个条目按以下格式包含7个字段(为了便于阅读,在分隔符前后添加了空格)。
As you can see, the file is colon (:) delimited, and each entry contains seven fields in the following format (with Spaces added before and after delimiter to ease reading).
调用matchlist返回正则表达式捕捉到的所有字段的列表(即任何与\(…\)分隔符中的模式部分匹配的元素)。
The call to matchlist returns a list of all the fields captured by the regex (that is, anything matched by those parts of the pattern inside \ (... \) delimiters).
