在文件cmd中的字符操作

Question

这是file.txt

hello
hai

我想创建一个程序来读取这个文件。然后用下一个字母替换每一个字母。保持所有数字和其他符号完整。

所以file。txt会变成

ifmmp
ibj

current已经尝试读取每个n，然后读取行中的每个字符，但是回显它们会导致它在不同的行中即

for /f "delims=" %%i in ('^<%path% findstr /n "^"') do (
set "line=%%i"
setlocal enabledelayedexpansion
set "line=!line:*:=!"
set "num=-1"
:loop
set /a num=num+1
call set "name2=%%line:~%num%,1%%"
if defined name2 (
rem set /a name2+=1 this statement wont work
    echo %name2%
goto :loop )

)

但是我得到的输出是

echo is off
e
l
l
o

任何想法?

Answer 1

set /a命令只能处理数字，您可以试试:

<>之前@echo off&setlocal设置"阿尔法= abcdefghijklmnopqrstuvwxyza"设置"test=hello hai"设置/a num=0:循环调用集"char=%%test:~%num%，1%%"如果没有定义char goto:eof调用集"alf1=%%alfa:*%char%=%%"如果"%char%" neq " " echo %alf1:~0,1%设置/a num+=1goto:循环之前

. .输出:

<>之前我f米米p我bj

这是一个ROT13批处理文件-你所描述的是ROT1翻译。也许这将为你工作，或者给你的想法，你可以修改它。
