The difference between delims and tokens and asterisks

Compare the difference in execution results between the following two pieces of code:

1、

@echo off

for /f "delims=" %%i in (test.txt) do echo /%%i/

pause

2、

@echo off

for /f "tokens=*" %%i in (test.txt) do echo /%%i/

pause

The .txt content is: abc . There are several spaces at the top of the line.

See the difference?

Why: "delims" means to cancel the default separator, so the contents of the line are copyed down, while "tokens" means getting everything on the line, but ignoring all spaces at the top of the line.
