批处理脚本需求：按指定规则批量重命名JPG文件

我需要一个可复制到任意含JPG文件的文件夹中运行的批处理文件，无需修改路径。要求按文件原顺序将JPG依次重命名为：1 - Front.jpg、2 - Back.jpg、3 - Left Side.jpg、4 - Right Side.jpg、5 - Top.jpg、6 - Bottom.jpg。我尝试了4个脚本，但都出现问题：

尝试的脚本及问题 #

第一个脚本 #

@echo off
setlocal enabledelayedexpansion

REM Get the current directory where the batch file is located
set "folderPath=%~dp0"

REM Initialize the counter
set "counter=1"

REM Define the desired filenames
set "filenames=Front Back Left Side Right Side Top Bottom"

REM Loop through each JPG file in the folder
for %%F in ("%folderPath%\*.jpg") do (
    REM Rename the file based on the counter and filenames
    for %%A in (!counter!) do (
        ren "%%F" "%%A - !filenames:~%%A,1!.jpg"
    )
    REM Increment the counter
    set /a "counter+=1" 
)

问题：文件被错误重命名为1 - r.jpg、2 - o.jpg这类仅提取单个字符的名称，因为!filenames:~%%A,1!是按字符位置截取，而非按空格分隔的条目获取。

第二个脚本 #

@echo off
setlocal enabledelayedexpansion

REM Get the current directory where the batch file is located
set "folderPath=%~dp0"

REM Initialize the counter
set "counter=1"

REM Define the desired filenames
set "filenames=Front Back Left Side Right Side Top Bottom"

REM Loop through each JPG file in the folder
for %%F in ("%folderPath%\*.jpg") do (
    REM Get the corresponding filename from the list
    for %%A in (!counter!) do (
        for %%B in (!filenames!) do (
            if %%A==1 (
                ren "%%F" "%%A - %%B.jpg"
            ) else (
                REM Increment the counter
                set /a "counter+=1"
                if %%A==2 (
                    ren "%%F" "%%A - %%B.jpg"
                ) else (
                    REM Increment the counter
                    set /a "counter+=1"
                    if %%A==3 (
                        ren "%%F" "%%A - %%B.jpg"
                    ) else (
                        REM Increment the counter
                        set /a "counter+=1"
                        if %%A==4 (
                            ren "%%F" "%%A - %%B.jpg"
                        ) else (
                            REM Increment the counter
                            set /a "counter+=1"
                            if %%A==5 (
                                ren "%%F" "%%A - %%B.jpg"
                            ) else (
                                REM Increment the counter
                                set /a "counter+=1"
                                if %%A==6 (
                                    ren "%%F" "%%A - %%B.jpg"
                                )
                            )
                        )
                    )
                )
            )
        )
    )
)

问题：生成重复序号的文件名，比如1 - Back.jpg、1 - Front.jpg，因为内层循环遍历所有文件名条目，每次循环都会执行重命名，导致单个原文件被多次重命名。

第三、第四个脚本 #

@echo off
setlocal enabledelayedexpansion

REM Get the current directory where the batch file is located
set "folderPath=%~dp0"

REM Initialize the counter
set "counter=1"

REM Define the desired filenames
set "filenames=Front Back Left Side Right Side Top Bottom"

REM Loop through each JPG file in the folder
for %%F in ("%folderPath%\*.jpg") do (
    REM Rename the file based on the counter and filenames
    for %%A in (!counter!) do (
        for %%B in (!filenames!) do (
            if %%A==%%B (
                ren "%%F" "%%A.jpg"
            )
        )
    )
    REM Increment the counter
    set /a "counter+=1" 
)

@echo off
setlocal enabledelayedexpansion

REM Get the current directory where the batch file is located
set "folderPath=%~dp0"

REM Define the desired filenames
set "filenames=Front Back Left Side Right Side Top Bottom"

REM Initialize the counter
set "counter=1"

REM Loop through each JPG file in the folder
for %%F in ("%folderPath%\*.jpg") do (
    REM Extract the corresponding filename from the list
    for %%A in (!counter!) do (
        for %%B in (!filenames!) do (
            if %%A==%%B (
                set "newName=%%B.jpg"
                ren "%%F" "!newName!"
            )
        )
    )
    REM Increment the counter
    set /a "counter+=1" 
)

问题：完全没有效果，因为逻辑错误——尝试将数字计数器%%A和文件名条目%%B进行相等判断，显然永远不会成立，因此不会执行任何重命名操作。

正确的批处理脚本 #

解决思路是将目标名称存储为数组，遍历JPG文件时按顺序取出数组中的对应条目进行重命名：

@echo off
setlocal enabledelayedexpansion

REM 定义目标名称数组，索引从1开始
set "name[1]=Front"
set "name[2]=Back"
set "name[3]=Left Side"
set "name[4]=Right Side"
set "name[5]=Top"
set "name[6]=Bottom"

set "counter=1"

REM 遍历当前文件夹下的所有JPG文件（按系统默认顺序）
for %%F in ("%~dp0*.jpg") do (
    REM 检查计数器是否在1-6范围内，避免超出条目数
    if !counter! leq 6 (
        ren "%%F" "!counter! - !name[!counter!]!.jpg"
    )
    set /a counter+=1
)

echo 重命名完成！
pause

脚本说明 #

1. 使用数组存储目标名称，避免空格分隔带来的拆分问题，尤其是Left Side这类包含空格的名称。
2. %~dp0直接指向批处理文件所在的文件夹，无需额外设置路径变量，复制到目标文件夹即可运行。
3. 添加了范围判断if !counter! leq 6，防止文件夹中JPG数量超过6个时出现无对应名称的情况。
4. 最后添加提示和暂停，方便查看执行结果。
