Remove Last Characters from my filenames in windows
提问by Xander Vane
Im quite new to batch programming and i wanted to remove the last characters on my filename.
我对批处理编程很陌生，我想删除文件名中的最后一个字符。
10_myfile_12345_6789.txt
11_myfile_12345_0987.txt
I want to remove the last 4 digits on my filename how i could do that?
我想删除文件名的最后 4 位数字，我该怎么做？
I have tried this
我试过这个
@echo off
setlocal enabledelayedexpansion
set X=3
set FOLDER_PATH=
pushd %FOLDER_PATH%
for %%f in (*) do if %%f neq %~nx0 (
set "filename=%%~nf"
ren "%%f" "!filename!%%~xf"
)
popd
PAUSE
but it removes on first and last characters, i only saw this here too, im still quite confused how this works
但它删除了第一个和最后一个字符，我也只在这里看到了这个，我仍然很困惑这是如何工作的

With your recent clarification - I would do the following.
根据您最近的澄清 - 我将执行以下操作。
@echo off
setlocal enabledelayedexpansion
set FOLDER_PATH=C:\Some\Path\
for %%f in (%FOLDER_PATH%*) do if %%f neq %~nx0 (
set "filename=%%~nf"
ren "%%f" "!filename:~0,-4!%%~xf"
)
PAUSE
This will change your examples
这将改变你的例子
10_myfile_12345_6789.txt
11_myfile_12345_0987.txt
Into
进入
10_myfile_12345_.txt
11_myfile_12345_.txt
If you want to remove the trailing _simply change !filename:~0,-4!to !filename:~0,-5!. This is simple string manipulation.
如果您想删除尾随，_只需更改!filename:~0,-4!为!filename:~0,-5!. 这是简单的字符串操作。
