使用正则表达式重命名多个文件 [英] Rename multiple files with regular expression

问题描述

我从互联网上下载了一些文件.在这些文件的名称字段中，每个' '字符均替换为"%20".我想重命名所有这些文件，但是文件数太多.因此，手动方法将很笨拙.我知道从命令行使用正则表达式可以做到这一点，但我对此并不十分熟悉.几乎不需要什么帮助.

I downloaded some files from internet. In the name field of those files each ' ' character is replaced by "%20". I want to rename all of those but number of files is too high. So manual approach would be clumsy. I know from command line with regular expression this can be done but I am not very familiar with it. So little help is needed.

总结是，我想通过用" "替换所有"%20"模式来重命名目录中的所有文件.我该怎么办?

Summary is, I want to rename all files in a directory by replacing all "%20" patterns with " ". How can I do it?

示例:

17%20Clipping.cpp --> 17 Clipping.cpp
14%20Mouse%20(Button)%20Listener.cpp --> 14 Mouse (Button) Listener.cpp

推荐答案

您可以使用接受正则表达式的命令rename重命名一组文件

you can rename a group of files using command rename that accept regular expression

例如，要重命名所有匹配"* .bak"的文件以去除扩展名，您可能会说

For example, to rename all files matching "*.bak" to strip the extension, you might say

rename 's/\.bak$//' *.bak

要将大写名称转换为小写，请使用

To translate uppercase names to lower, you'd use

rename 'y/A-Z/a-z/' *

和您的答案:

rename 's/%20/ /' *.cpp
