命令行批从它的文件名中删除_ [英] command line batch remove _ from its file name

问题描述

我有多个文件，并想重新命名其文件。结果
例如，我有

I have multiple files and would like to rename its file.
For example, I have

2014_19_24_english_test.doc

"2014_19_24_english_test.doc"

和将其更改为

2014 19 24英语Test.doc的

"2014 19 24 english test.doc"

这是我迄今所做的：

for /f "delims=" %%f in ('dir /b *.hwp') do ren "%%~f" "%%~nf:_= %%~xf"

这是行不通的。任何帮助将是AP preciated，

and this is not working. Any help would be appreciated,

推荐答案

您不能使用的子字符串替换语法变量，所以你需要一个临时变量来做到这一点采用延迟扩展：

You cannot use the substring replacement syntax with for variables, so you need an interim variable to do that, using delayed expansion:

setlocal EnableDelayedExpansion
for /f "delims=" %%f in ('dir /b *.hwp') do (
    set "FNAME=%%~nf"
    ren "%%~ff" "!FNAME:_= !%%~xf"
)
endlocal
