批量替换文本文件内的文本（Linux / OSX命令行） [英] Batch replace text inside text file (Linux/OSX Commandline)

问题描述

例如，我要替换http：//的每个实例。与rtmp：//。

这些文件具有.txt扩展名，分布在多个文件夹和子文件夹中。

我基本上是在寻找一种方式/脚本，通过每个文件夹/子文件夹和每个文件，如果它发现里面的http替换为rtmp。

提前感谢。

解决方案

c $ c>查找和 sed ：

  find。 -type f -name \ * .txt -exec sed -i.bak's | http：// | rtmp：// | g'{} + 
  

这将创建每个文件的备份。我建议你检查几个，以确保它做了你想要的，然后你可以使用

 查找删除它们。 -name \ * .bak -delete 
  

I have hundreds of files where I need to change a portion of its text.

For example, I want to replace every instance of "http://" with "rtmp://" .

The files have the .txt extention and are spread across several folders and subfolder.

I basically am looking for a way/script that goes trough every single folder/subfolder and every single file and if it finds inside that file the occurrence of "http" to replace it with "rtmp".

Thanks in advance.

解决方案

You can do this with a combination of find and sed:

find . -type f -name \*.txt -exec sed -i.bak 's|http://|rtmp://|g' {} +

This will create backups of each file. I suggest you check a few to make sure it did what you want, then you can delete them using

find . -name \*.bak -delete
