双感叹号与双%号的区别是什么呢
for的do里面好像看到的是!n!
其他的像echo看到的是%n%
这个可以讲讲吗
What is the difference between double exclamation marks and double percent signs?
I seem to see!n! in the do of for
Others like echo see %n%
Can you talk about this?

自己试了一下，把word当成分隔符
@ echo off
set "a=333ps555psssword=123 456 789"
for /f "tokens=1* delims=word" %%i in ("%a%") do set b=%%i&set num=%%j
echo %b:~0,-4% %num%
pause
Tried it myself, using word as a delimiter
@ echo off
set "a=333ps555psssword=123 456 789"
for /f "tokens=1* delims=word" %%i in ("%a%") do set b=%%i&set num=%%j
echo %b:~0,-4% %num%
pause

这个问题值得研究研究．．．就是当 delims=字符串时 以什么样的方式分割．
This question is worth studying... That is, when delims = string, in what way it is split.

delims=字符串时 举例:
如果字符串是abc
则起到分割作用的分割符有
a,b,c,ab,ac,bc,abc
学过排列组合的就知道不管字符的长度为多少,分割符总是为:
Cn1+Cn(n-1)..........Cnn,就有这么多的可能!
When delims= is a string: For example: If the string is abc, then the delimiters that play a splitting role are a, b, c, ab, ac, bc, abc. Those who have studied permutations and combinations will know that no matter the length of the character, the number of possible delimiters is always: Cn1 + Cn(n-1) +... + Cnn, there are so many possibilities!

只能主观这么认为 我的意思是字符串在被分割的字符串中有什么特点时 已什么样的方式分割
我也是实验知道的 列如若delims=中的字符串具有唯一性时 会以第整串字母作为分割符 否则 会以第一个字符作为分割符 不够准确 望大虾指出!
Can only be subjectively considered. I mean, what are the characteristics of the string when it is being split, and in what way is it split? I also know from experiments. For example, if the string in delims= has uniqueness, it will use the entire string of letters as the delimiter; otherwise, it will use the first character as the delimiter. It's not accurate enough. Hope the experts can point out!

"delims=abcedef"
无论 那种情况 delims 的分割 是以 等号 后的每一个字符作为分隔符的
只是在 所谓的 "唯一性" 时 看起来 像 以整个字符串为分隔符而已

"delims=abcedef"
No matter what the situation is, the splitting of delims is using each character after the equal sign as the delimiter.
It just seems to use the entire string as the delimiter when it is said to be "unique".

经测试，还可以用一个汉字作分隔符，
我的理解，分隔符是 一个字节

After testing, it can also use a single Chinese character as a separator.
My understanding is that the separator is one byte

Oh. So that's the case. Does that mean it can only use a single letter or symbol as a separator?

经测试，分隔符可以是一个汉字
比如，有一文本文件test.txt,其内容如下
-------------------------------------------------------------------------------
111111你2222222你3333333333你4444444
55555你66666你7777777777777777777你88888
9999你00000你aaaaaaaa你bbbbbb
---------------------------------------------------------------------------------
批处理代码
@echo off
FOR /F "tokens=1,3,4 delims=你" %%a in (test.txt) do @echo %%a %%b %%c
pause
执行该批处理后，可以发现汉字“你”确实可以作为分隔符
字节"

For example, there is a text file test.txt, and its content is as follows
-------------------------------------------------------------------------------
111111You2222222You3333333333You4444444
55555You66666You7777777777777777777You88888
9999You00000YouaaaaaaaaYoubbbbbb
---------------------------------------------------------------------------------
Batch processing code
@echo off
FOR /F "tokens=1,3,4 delims=You" %%a in (test.txt) do @echo %%a %%b %%c
pause
After executing this batch processing, it can be found that the Chinese character "You" can indeed be used as a delimiter

楼上的兄弟挖坟能力好强……看了半天，才知道是2年前的帖子了……不过也很经典
The brother upstairs has an amazing ability to dig up old posts... After reading for a long time, I just realized it's a post from two years ago... But it's also very classic
