批处理脚本可反转文件名中日期的顺序 [英] Batch script to invert the order of a date in file names

问题描述

我想使用批处理脚本来重命名使用以下命名方案的一堆文件:

I wanted to use a batch script to rename a bunch of files which are using the following name scheme:

File 2-9.pdf
File 3-9.pdf
File 4-9.pdf
[...]

我想反转数字，以便它们变为...

I want to invert the numbers so that they will become...

File 9-2.pdf
File 9-3.pdf
File 9-4.pdf
[...]

通常，我会搜索重复的字符串并将其替换，但是在这种情况下，字符串随每个文件而变化，因此我不知道该如何处理.有什么想法吗?

Normally I would search for the repeating string and replace it, but in this case the string changes with each file, so I don't know how to go about it. Any ideas?

感谢您的阅读.

我在Windows上，正在寻求创建.bat文件.像

I am on Windows, I am seeking to create a .bat file. Something like

For %%# in ("file-path") Do (
    Set "File=%%~nx#"
    Ren "%%#" "!File:%Pattern%=%Replace%!"
)

推荐答案

相对容易.不要使用搜索并替换"，而是使用适当的标记和定界符来分割文件名:

relatively easy. Don't use "search and replace", but use proper tokens and delimiters to split your filenames:

@echo off 
for %%f in (*.pdf) do (
  for /f "tokens=1,2,3 delims=- " %%a in ("%%~nf") do (
    ECHO ren "%%~f" "%%a %%c-%%b%%~xf"
  )
)

(注意:故障排除后请删除 ECHO 以启用重命名命令)

(Note: remove the ECHO after troubleshooting to enable the rename command)
