如何使用批处理文件替换文本文件中第二行的字符串?

前端之家收集整理的这篇文章主要介绍了如何使用批处理文件替换文本文件中第二行的字符串?前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
好吧,所以我一直在研究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(或更多行)文本的文本文件.然后它接受该文件并将每个字母的每个实例更改为其相应的数字(例如,如果文本文件的第一行表示“可编程”,则程序将字母“a”的所有实例更改为1和“b”进入2,依此类推,直到它全部为数字.然后它将显示为“16 18 15 7 18 1 13 1 2 12 5”)并且我会通过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

但是,此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中的字母“a”.

我还尝试在程序开头拆分文档,以便当用户键入第一行的文本时,它将其发送到单独的隐藏文件(text1.txt),而不是仅发送用户的所有文本行类型,分成一个文本文件(text.txt)

我是这样做的:

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会非常高效且非常耗时,并且对于每一行(或在此情况下,文件)执行此操作用户输入…如果我将所有这些放在上下文中会有所帮助,这里是我的程序到目前为止的脚本,对于“:LOADING”下标我目前正在使用我之前解释过的方法,我将这些行拆分成文件.

如果你有一个解决方案,我会很高兴听到它,因为我一直在寻找解决这个问题的高低,但一无所获.此外,如果任何人注意到我的脚本中的任何其他错误错误,请随时发表评论

提前致谢!

解决方法

让我向您介绍我的朋友 for loop.将用户输入的所有行保存到单个文件中.我将此文件称为input.txt.使用带有/ f开关的for循环和delims =选项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 =,它只会读到第一个空白字符.

对于它读取的每一行,进行文本替换.批处理编程的“问题”是在for循环中设置变量时,必须在文件顶部添加set setlocal enabledelayedexpansion,然后使用!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包含以下内容

programable
this is line 2
third line

然后输出看起来像这样:

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

如你所见,我遗漏了假延迟.我很喜欢我的节目. 原文链接:https://www.f2er.com/html/228325.html
