如何使用批处理文件替换文本文件第二行的字符串？

Question

好吧，我一直在处理一个相当复杂的批处理文件，它基本上要求用户创建一个包含 6 行（或更多）文本的文本文件。然后它获取该文件并将每个字母的每个实例更改为其各自的数字（例如，如果文本文件的第一行说“可编程”，那么程序会将字母“a”的所有实例更改为 1 和“b”进入 2 以此类推，直到全部为数字。然后它将显示为“16 18 15 7 18 1 13 1 2 12 5”），我将使用以下脚本来做到这一点：

set /p var=< text.txt
set var=%var:a=1%
echo.%var% >> text.txt

然而，这个脚本的唯一问题是它只会将第一行的字母 a 更改为 1，而不是文档其余部分的字母“a”。

我还尝试在程序开始时拆分文档，以便当用户键入第一行的文本时，它会将其发送到单独的隐藏文件 (text1.txt)，而不仅仅是发送所有文本行用户输入到一个文本文件 (text.txt) 中

我是用这个来做的：

set /p line1=type the first line:
echo %line1% >> text1.txt
attrib +h text1.txt
set /p line2=type the second line:
echo %line2% >> text2.txt
attrib +h text2.txt
:: ########################################################################
:: Im not going to repeat this 6 times but hopefully you get my point
:: ########################################################################

现在将行拆分为单独文件的问题在于，将每个字母的所有实例更改为各自的数字，并为每一行（或在这种情况下，文件(行到文件中。

如果您有解决方案，我会很高兴听到它，因为我一直在寻找解决此问题的方法，但一无所获。另外，如果有人注意到我的脚本中的任何其他错误或错误，请随时发表评论！

提前致谢！

让我把你介绍给我的朋友for loop。将用户输入的所有行保存到一个文件中。我将此文件称为input.txt。使用带有/f 开关和delims= 选项的for 循环循环遍历文件中的每一行，并将这些行存储在变量%%i 中。如果没有delims=，它将只读取到第一个空白字符。

对于它读取的每一行，进行文本替换。批处理编程的“陷阱”是当您在for 循环中设置变量时，您必须在文件顶部添加行setlocal enabledelayedexpansion，并使用! 而不是% 来访问变量内容.

@echo off
setlocal enabledelayedexpansion
for /f "delims=" %%i in (input.txt) do (
echo translating "%%i"... ^<insert fake delay here^>
set var=%%i
set var=!var:a=1 !
set var=!var:b=2 !
set var=!var:c=3 !
set var=!var:d=4 !
set var=!var:e=5 !
set var=!var:f=6 !
set var=!var:g=7 !
set var=!var:h=8 !
set var=!var:i=9 !
set var=!var:j=10 !
set var=!var:k=11 !
set var=!var:l=12 !
set var=!var:m=13 !
set var=!var:n=14 !
set var=!var:o=15 !
set var=!var:p=16 !
set var=!var:q=17 !
set var=!var:r=18 !
set var=!var:s=19 !
set var=!var:t=20 !
set var=!var:u=21 !
set var=!var:v=22 !
set var=!var:w=23 !
set var=!var:x=24 !
set var=!var:y=25 !
set var=!var:z=26 !
echo !var!
)

如果input.txt 有这些内容：

programable
this is line 2
third line

然后输出将如下所示：

C:\batch>encode.cmd
translating "programable"... <insert fake delay here>
16 18 15 7 18 1 13 1 2 12 5
translating "this is line 2"... <insert fake delay here>
20 8 9 19  9 19  12 9 14 5  2
translating "third line"... <insert fake delay here>
20 8 9 18 4  12 9 14 5

如您所见，我忽略了假延迟。我喜欢我的程序快。 :)
