如何使用awk或者sed替换文本？ [英] How to replace text using sed or awk?

问题描述

我有以下的JSON文件：

I have the following json file:

 { "last_modified": {
         "type": "/type/datetime", 
         "value": "2008-04-01T03:28:50.625462" }, 
     "type": { "key": "/type/author" }, 
     "name": "National Research Council. Committee on the Scientific and Technologic Base of Puerto Rico"s Economy.", 
     "key": "/authors/OL2108538A", 
     "revision": 1 }

name的值有双引号，我只想用一个单引号（而不是其他任何双引号）替换此双引号。我该怎么办呢？

The name value has a double quote and I only want to replace this double quote with a single quote (not any other double quote). How can I do it?

推荐答案

如果你想repleace单个字符出现的所有，你也可以使用命令 TR ，比awk或者sed简单：

If you want to repleace all occurences of a single character, you can also use the command tr, simpler than sed or awk:

   cat myfile.txt | tr \" \'

注意，两个引号转义。如果您有其他字符不是引号，你只写：

Notice that both quotes are escaped. If you have other chars than quotes, you just write:

   cat myfile.txt | tr a A

编辑：请注意，这个问题被编辑后，这个答案不再有效：它取代所有的双引号，不仅是名称属性里面有一个

Note that after the question was edited this answer is no longer valid: it replaces all double quotes, not only the one inside the Name property.
