查找并重命名没有扩展名的文件? [英] Find and rename files with no extension?

问题描述

因此，我有一堆没有扩展名的文件.我想编写一个Windows批处理脚本，该脚本将:

So, I've got a bunch of files with no extension. I want to write a windows batch script that will:

1. 查找没有扩展名的文件(在指定文件夹中)
2. 在文件名的末尾添加.bla

我真是个Windows批处理脚本菜鸟，我什至不知道从哪里开始.有建议吗?

I'm such a windows batch script noob I don't even know where to start. Suggestions?

推荐答案

对于Windows批处理文件，这将仅将不带.bla扩展名的文件重命名:

For windows batch files, this will rename only files with no extension to the .bla extension:

rename *. *.bla

请注意，第一个参数是星号和点:*.

Notice the first argument is a star and a dot: *.

第二个参数是:* .bla

The second argument is: *.bla

起始点(*.)组合表示在这种情况下没有扩展名的文件.

The start dot (*.) combination represents files with no extensions in this context.

之前:

06/21/2009  11:57 PM                 6 test
06/21/2009  11:57 PM                 7 test.exe
06/21/2009  11:57 PM                 7 test2

之后:

06/21/2009  11:57 PM                 6 test.bla
06/21/2009  11:57 PM                 7 test.exe
06/21/2009  11:57 PM                 7 test2.bla

其他说明:相反的命令行会将所有.bla文件重命名为没有扩展名文件.

Additional note: The opposite commandline would rename all .bla files into no extension files.

编辑:

对于递归重命名文件时，子目录之间没有扩展名(不支持路径中的空格):

For recursively renaming files with no extension across subdirectories (doesn't support spaces in paths):

@echo off
FOR /F %%i in ('dir /b/s/A-d') DO (
  if "%%~xi" == "" rename "%%~fi" "%%~ni.bla"
)

@echo off
for /f "tokens=* delims= " %%i in ('dir /b/s/A-d') DO (
  if "%%~xi" == "" rename "%%~fi" "%%~ni.bla"
)
