src.txt是你原来的文本，执行完后dst.txt是过滤后的文本，将cmd切换到保存src.txt的目录下，再执行上边一行
哈哈....终于找到le

src.txt is your original text, after execution, dst.txt is the filtered text. Switch the cmd to the directory where src.txt is saved, then execute the above line
Hahaha.... Finally found it
What I want is this
Give a thumbs up....

set %%i=a 有什么用处？
The sentence "set %%i=a" is used to set the variable represented by %%i to the value "a". In the context of this `for /f` loop, it's likely part of a process to initialize or assign a default value to each variable that is read from the `test.txt` file.

还有 如果只是想删除相邻重复行的内容怎么办
比如
aaa
aaa
bbb
aaa
aaa
aaa
ccc
ddd
ccc
要求处理后为：
aaa
bbb
aaa
ccc
ddd
ccc

What is the use of `set %%i=a`?
Also, if you just want to delete adjacent duplicate lines, how to do it?
For example:
aaa
aaa
bbb
aaa
aaa
aaa
ccc
ddd
ccc
The desired result after processing is:
aaa
bbb
aaa
ccc
ddd
ccc
