[英]How to rename a folder the same as the filename of the first file inside that folder using Windows batch programming?
I have a group of about 3,000 folders named XYZ-1 through XYZ-3000.我有一组大约 3,000 个文件夹,名为 XYZ-1 到 XYZ-3000。 Inside those folders are groups of image files and a description text file.
在这些文件夹中是一组图像文件和一个描述文本文件。 Such as:
如:
The number of .jpg
files differs in each folder, but there's always a single description file.每个文件夹中
.jpg
文件的数量不同,但始终只有一个描述文件。 Each directory's image files have a different name, for example `XYZ-1 might contain Property123, while XYZ-10 might contain Easement789.每个目录的图像文件都有不同的名称,例如`XYZ-1 可能包含 Property123,而 XYZ-10 可能包含 Easement789。
I need to rename the folders containing the files after the "Property123" part of the .jpg files.我需要在 .jpg 文件的“Property123”部分之后重命名包含文件的文件夹。 Ideally I would truncate off the trailing digits and the underscore, but even if they were left on, it would be better than the XYZ-1 names.
理想情况下,我会截断尾随数字和下划线,但即使保留它们,它也会比 XYZ-1 名称更好。
I'm working on a batch file to do just that, but mine won't run and I can't figure out why.我正在处理一个批处理文件来做到这一点,但我的无法运行,我不知道为什么。
Here's what I have:这是我所拥有的:
for /d %%D in (*) do (
set "_dir=%%D"
set /a "_first=1"
cd "%%D"
for %%F in (*) do (
if %_first%==1 set "_name=%%~nF"
set /a "_first=0"
)
cd ..
ren %_dir% %_name%
)
Unfortunately, when I run it, the command window just closes immediately.不幸的是,当我运行它时,命令窗口会立即关闭。 I tried putting a pause command at the end, but that didn't keep the window open.
我尝试在最后放置一个暂停命令,但这并没有让窗口保持打开状态。 Nothing happens to the files/folders.
文件/文件夹没有任何反应。
I've tried my syntax from a command line and everything looks OK.我已经从命令行尝试了我的语法,一切看起来都很好。 So I don't know what the problem is.
所以我不知道是什么问题。 Can I get a little help, please?
我能得到一点帮助吗?
Try this:尝试这个:
@echo off
setlocal EnableDelayedExpansion
for /d %%D in (*) do (
set "_dir=%%D"
set "_name=%%D"
set /a "_first=1"
cd "%%D"
for %%F in (*) do (
if !_first!==1 set "_name=%%~nF"
set /a "_first=0"
)
cd ..
ren !_dir! !_name!
)
You need to use setlocal EnableDelayedExpansion here, and use !您需要在此处使用 setlocal EnableDelayedExpansion,并使用 ! instead of % inside for loops.
而不是 % 在 for 循环中。
I also added set "_name=%%D" so it won't try to change a second folder to the first folders name if that folder doesn't contain files我还添加了 set "_name=%%D" 所以如果该文件夹不包含文件,它不会尝试将第二个文件夹更改为第一个文件夹名称
EDIT:编辑:
also takes into consideration the underscore part:还考虑了下划线部分:
@echo off
setlocal EnableDelayedExpansion
for /d %%D in (*) do (
set "_dir=%%D"
set "_name=%%D"
set /a "_first=1"
cd "%%D"
for %%F in (*) do (
if !_first!==1 (
set "_name=%%~nF"
set /a "_first=0"
if NOT "!_name!"=="!_name:_=!" (
set "subfix=!_name:*_=!"
for /f "delims=" %%B in ("!subfix!") do set "_name=!_name:_%%B=!"
)
)
)
cd ..
ren !_dir! !_name!
)
