Can I do this with the for command like this?

@echo off
set "var=333ps555psssword=123 456 789"
for /f "tokens=1* delims=psssword" %%i in ("%var%") do set str=%%i&set num=%%j
echo %str% %num%
pause

My original intention was
Set str=333ps555
num==123 456 789
But the result is
str=333
num=555psssword=123 456 789

Why does the result of my run use p or s as the delimiter instead of psssword?

delims=psssword
Will use these letters as delimiters; not just p and s, w, o, r, d will also be used as delimiters;

delims cannot be used as delimiters for the string;

Oh. So that's it, it means it can only use a single letter or symbol as a separator, right?

C:\>echo 333ps555psssword=123 456 789|gawk "BEGIN{FS=\"psssword\"}{str=$1;num=$2;print \"str=\"str\"\nnum=\"num}"

str=333ps555

num==123 456 789

This is how the delims option of the for command works.

To use the string "psssword" as a delimiter, I only know that the gawk tool can do it. You can find the download address by searching in the forum.

C:\>echo 333ps555psssword=123 456 789|gawk "BEGIN{FS=\"psssword\"}{str=$1;num=$2;print \"str=\"str\"\nnum=\"num}"

str=333ps555

num==123 456 789

Oh. Thanks, but I won't use tools,...
Mainly learning batch processing,...

@echo off

set "var=333ps555psssword=123 456 789"

set "var=%var:psssword=_%"

for /f "tokens=1* delims=_" %%a in ("%var%") do set str=%%a&set num=%%b

echo str=%str%

echo num=%num% 

pause

Sometimes using some tools can solve many problems, but I don't force it.

Although the delims option of the for command doesn't support string splitting, if you want to achieve your goal, changing the idea might also work:

@echo off

set "var=333ps555psssword=123 456 789"

set "var=%var:psssword=_%"

for /f "tokens=1* delims=_" %%a in ("%var%") do set str=%%a&set num=%%b

echo str=%str%

echo num=%num% 

pause

Dear all experts, why don't you write comments for the commands? It makes us noobs confused. Some strange characters used in them can't be found online for their usage. As a result, reading them is like not reading. I don't know the specific meaning of each command, and then I can't apply what I've learned to other problems.

It's like looking at things through a mist! 3D pictures are seen like that. If you persist in looking for three months, you'll understand. I started looking through a mist last December, and now I can see 3D pictures.

The first part was understood, but the latter part is like天书.

Yeah, it's all like天书.

A few seconds for the 3D picture is okay.

Learned.
