使用批处理文件增加文件版本号 [英] Incrementing file version numbers with batch file

问题描述

我正在尝试执行与此几乎相同的操作:

I am trying to do something nearly identical to this: How do I increment a folder name using Windows batch?

基本上，我想创建一个批处理文件以扫描目录，确定最高版本号，然后依次创建下一个.因此，如果目录包含:

Essentially, I want to create a batch file to scan through a directory, determine the highest version number, and then create the next one in sequence. So if the directory contains:

New folder V1.0
New folder V1.1
New folder V1.3

我希望批处理文件添加一个新文件夹V1.4.应该是可行的.问题是我找到了脚本:

I want the batch file to add a New folder V1.4. Should be doable. The problem is that the script I found:

@echo off
setlocal enableDelayedExpansion
set "baseName=New_Folder"
set "n=0"
for /f "delims=" %%F in (
  '2^>nul dir /b /ad "%baseName%*."^|findstr /xri "%baseName%[0-9]*"'
) do (
  set "name=%%F"
  set "name=!name:*%baseName%=!"
  if !name! gtr !n! set "n=!name!"
)
set /a n+=1
md "%baseName%%n%"

不适用于名称为IE的带有空格的文件夹，它不能用于"New_Folder"，而不能用于"New Folder".我尝试用^和的各种排列来转义空格，例如，

doesn't work with folders with spaces in the name IE it works with 'New_Folder' but not 'New Folder'. I've tried escaping the spaces with various permutations of ^ and ", for example,

set "baseName=New^ Folder"
set "baseName=New" "Folder"
set "baseName=New""^ ""Folder"

等等，但是，我还没有开始工作.

and so forth, however, I haven't gotten it to work.

我知道我可以通过更改文件名以使用下划线来解决问题，但是在这一点上，我想知道为什么不起作用以及如何解决./p>

I am aware that I could solve the problem by changing my file names to use underscores, but at this point, I want to know why it doesn't work and how to fix it.

推荐答案

在这里有效.

@echo off
setlocal enableDelayedExpansion
set "baseName=New Folder V1."
set "n=0"
for /f "delims=" %%F in (
  '2^>nul dir /b /ad "%baseName%*"^|findstr /xri /c:"%baseName%[0-9]*"'
) do (
  set "name=%%F"
  set "name=!name:*%baseName%=!"
  if !name! gtr !n! set "n=!name!"
)
set /a n+=1
md "%baseName%%n%"
