如果有特定前缀，CMD 重命名文件，如果所有文件都有（或没有）前缀，则工作，如果不同，则即使有一个也会失败

Question

我正在为在改装的 PlayStation 2 上使用 POPStarter 的人制作一个 .BAT 脚本。

使用它需要 .ELF 文件具有四种格式之一（取决于游戏的加载方式。）

XX.somegame.ELF 用于从 USB 加载
PP.somegame.ELf 用于从 PS2 硬盘上的每个游戏分区加载
__.somegame.ELF 用于从 PS2 硬盘上每个游戏的隐藏分区加载
somegame.ELF 用于从 PS2 硬盘上的 __.POPS 分区加载

此脚本应重命名要以相应格式使用的文件。

我有我的代码，如果所有 .ELF 文件都有一个前缀（这三个文件中的哪一个无关紧要）或者如果它们都缺少前缀，那么命令运行完美，但是即使有一个不同的文件（都有前缀，一个没有，或者都没有前缀，一个有）所有文件都被视为不同的文件。

我的代码是：

@echo off
setlocal ENABLEDELAYEDEXPANSION
Mode con: cols=115 lines=40
color 17
set "logfile=ELF_Test_Log.txt"
Set "Replace1=XX"
Set "Replace2=__"

:loading部分出现了四次（对应4个期望的结果）

使用两个文件，当它们具有相同的结构时，这是读出的日志

Sun 09/20/2015 - 14:19:05.08 Menu Loaded

Sun 09/20/2015 - 14:19:12.62 End Program

这是当所有 somegame.ELF 而只有一个 XX.somegome.ELF:

时的日志输出

我该如何补救这最后遗漏的部分？

编辑 - 添加了完整的 BAT 脚本 .....

Answer 1

你并没有真正告诉我们你的脚本应该做什么。

但我认为问题在于您实际上只测试了第一个文件。第一个 for 循环实际上从不循环。它只是检查它获得的第一个文件并跳转到相应的 "action" 循环。

您想测试每个文件并据此采取行动。为此，您只需要一个 for 循环：

for /f "delims=" %%a in ('dir /a-d /b *.elf') do (

    set F=%%~na
    set F=!F:~3!
    set ADD=1
    if %%a == %Replace1%.!F!%%~xa set ADD=0
    if %%a == %Replace2%.!F!%%~xa set ADD=0
    if %%a == %Replace3%.!F!%%~xa set ADD=0

    if !ADD! == 1 (

        echo File %%a has no Prefix, Adding %Replace1%. 
        ren "%%a" "%Replace1%.%%a"
        pause

    ) else (

        set F=%%a
        set F=!F:~3!
        echo File %%a has a prefix, renaming to %Replace1%.!F! 
        ren "%%~a" "%Replace1%.!F!"

    )
)

如果有特定前缀，CMD 重命名文件，如果所有文件都有（或没有）前缀，则工作，如果不同，则即使有一个也会失败

CMD rename files if has certain prefix, works if ALL files have (or don't have) prefix, fails if even one if different

loops

cmd

file

batch-file

file-rename
