[文件操作] 【分享】批处理把俩个文件名称互相交换

我看论坛没有，所以分享
比较好奇的是运用场景在哪里啊.....

把俩个文件名称交换【拖动到bat处理】

@echo off
if "%~2"=="" (
    echo Drag two files into this bat to swapping files names
    pause
    exit /b
)
if not "%~3"=="" (
    echo Can only swap two files names
    pause
    exit /b
)
set "file1=%~n1"
set "file2=%~n2"
set "ext1=%~x1"
set "ext2=%~x2"
set "temp=%random%"
ren "%~1" "%temp%%ext1%"
ren "%~2" "%file1%%ext2%"
ren "%temp%%ext1%" "%file2%%ext1%"
复制代码

以下代码可以接受同目录中两个文件一次拖入，亦可接受两个不同目录中的文件逐个拖入...

@echo off & if "%~2"=="" set/p="命令行须拖入或输入两个文件参数"&exit/b
ren "%~1" "%~nx2.tmp" && ren "%~2" "%~nx1" && ren "%~dp1%~nx2.tmp" "%~nx2"
pause&exit/b

用随机数作为临时文件名存在文件名重复可能吧，数字文件名还是挺常见的。

@echo off
if "%~3" equ "" (
	if "%~2" neq "" (
		ren "%~2" "$"
		ren "%~1" "%~nx2"
		ren "%~dp2\$" "%~nx1"
	) else (
		echo Drag two files into this bat to swapping files names
	)
) else (
	echo Can only swap two files names
)
pause

temp是默认环境变量建议改为自定义变量.bat

@echo off
if "%~2"=="" (
    echo Drag two files into this bat to swapping files names
    pause
    exit /b
)
if not "%~3"=="" (
    echo Can only swap two files names
    pause
    exit /b
)
set "MyTemp=%random%"
ren "%~1" "%MyTemp%%~x1"
ren "%~2" "%~n1%~x2"
ren "%MyTemp%%~x1" "%~n2%~x1"

4个set去掉.bat

@echo off
if "%~2"=="" (
    echo Drag two files into this bat to swapping files names
    pause
    exit /b
)
if not "%~3"=="" (
    echo Can only swap two files names
    pause
    exit /b
)
set "temp=%random%"
ren "%~1" "%temp%%~x1"
ren "%~2" "%~n1%~x2"
ren "%temp%%~x1" "%~n2%~x1"
