推荐答案

RENAMER.CMD

RENAMER.CMD

@echo off
setlocal enableextensions enabledelayedexpansion
for %%i in (*) do (set name=%%i && ren "!name!" "!name:~7!")
endlocal

说明:

setlocal / endlocal 东西只是确保不管您的默认命令行设置如何，脚本都可以正常工作.如果您确保默认情况下启用了命令扩展名和延迟扩展名，或者使用 cmd/e:on/v:on 启动命令提示符，则这些行是可选的.

The setlocal / endlocal stuff just makes sure that the script will work no matter what your default commandline settings are. Those lines are optional if you make sure that command extensions and delayed expansion are enabled by default, or if you start your command prompt using cmd /e:on /v:on.

for 语句是关键.它使用(*)选择目录中的每个文件.如果只想更改带有某些扩展名的文件，则可以使用其他模式，例如(*.avi).然后！name:〜7！从前面减去七个字符. 设置/?列出了您可以执行的其他一些操作.大多数示例使用％代替！，但是所有字符串操作都可同时使用.

The for statement is the heart of the thing. It selects every file in the directory using (*). If you only want to change files with certain extensions you can use a different pattern such as (*.avi). Then !name:~7! takes seven characters off the front. set /? lists some of the other manipulations you can perform. Most of the examples use % instead of ! but all string manipulations work with both.

您可以在！内执行％替换.替代.

You can perform a % substitution inside a ! substitution.

@echo off
setlocal enableextensions enabledelayedexpansion
set numtrim=7
for %%i in (*) do (set name=%%i && ren "!name!" "!name:~%numtrim%!")
endlocal
