Unix Shell循环遍历文件并替换文本 [英] Unix Shell Loop through files and replace texts

问题描述

我对这些东西还很陌生，我需要一个Shell文件来循环遍历文件夹中的所有".xml"文件，并进行一些文本替换. 到目前为止，我已经提出了这个建议:

I am fairly new to this stuff, and I need a shell file to loop through all ".xml" files in a folder, and do some text replacements. So far I have come up with this:

sed "s/old_text/new_text/g" testfile.xml -i

但是，我希望它能在当前文件夹中的所有xml文件上运行，而不仅仅是在"testfile.xml"上运行.此外，如何备份原始文件?

However, I want this to run on all xml files in the current folder, not just on "testfile.xml". Furthermore, how can I make a backup of the original file ?

欢迎任何输入！ 非常感谢！

Any input is more than welcomed! Thankls a lot!

推荐答案

要在所有xml文件上运行sed，只需指定通配符

To run sed on all the xml files, just specify the wildcard

sed "s/old_text/new_text/g" *.xml -i

要创建备份，只需在-i之后指定扩展名:

To create a backup, just specify the extension after -i:

sed "s/old_text/new_text/g" *.xml -i~

请注意，通常最好使用XML感知工具来处理XML.

Note that's usually better to use XML aware tools to handle XML.
