批处理文件数组的创建/修改 [英] Batch file Array creation/modification
问题描述
所以我正在尝试使用批处理来创建数组，我知道这是原始的，但是我正在从头开始学习代码，所以批处理是我非常想学习的东西，无论如何我还是要跳到其他东西，我知道我可以使用以下语法创建数组:
so i am trying to make an array using batch, i know, primitive, but i'm learning code from the ground up, so batch is something i'd love very much to learn before i jump to something else, anyways, i know i can create an array using this syntax:
@echo off
set a[0] = 1
set a[1] = 2
set a[2] = 3
set a[3] = my input variable here
@echo off
set a[0] = 1
set a[1] = 2
set a[2] = 3
set a[3] = my input variable here
我的问题是，如何使用用户输入向阵列添加新行或修改现有行?
My question is, how can i add a new line to the array or modify an existing one using user input ?
我的意思是我想将用户输入变量用作新行或修改数组上的现有行！
I mean that i'd like to use a user input variable as a new line or modify an existing line on the array !
推荐答案
所以我在DOS论坛上找到了我需要的东西，这很简单:
so i found what i needed on a DOS forum, it was pretty simple:
< myfile.txt (
set /p line1=
set /p line2=
set /p line3=
set /p line4=
set /p line5=
)
set line
< myfile.txt (
set /p line1=
set /p line2=
set /p line3=
set /p line4=
set /p line5=
)
set line
我仍然想修改一些东西，例如添加自动的行数增量，因此每次将新字符串添加到文本文件时，它都会自动创建一个新的字符串(设置/p line"n" =)，所以现在它可以满足我的需要，它可以读取指定文本文件中的每一行，并将其放置在列表中的变量上，一旦存在，我就可以将变量用于所需的对象，而不必是一个数组，但可以足够接近，唯一的事情是，如果您未实现自动行增量"，则必须手动创建空变量，就像我在上面的代码示例中所做的那样，您可以看到我最多写了"5个变量"，因此如果输入第6个，仍会将其添加到文本文件中，但脚本不会列出它，因此需要自动增加空变量.
i still want to modify some things, like adding automatic line count increment, so every time a new string is added to the text file, it will automatically create a new (set /p line"n"=) so right now it works for what i want, it reads each line on the specified text file, and places it on a variable on the list, once is there, i can use the variable for whatever i need, not exactly an array, but close enough, only thing, if you do not implement "automatic line increment" you have to manually create the empty variable, as i did on the code example above, you can see i wrote up to "5 variables" so if you enter a 6th, it will still add it to the text file, but the script won't list it, therefore, the need to automatically increment the empty variables.
