This article mainly introduces the difference between delims= and tokens= asterisks in batch processing. It is very detailed and has a certain reference value. Friends who are interested must read it!

Compare the execution results of 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 content of test.txt is: abc. There are several spaces at the beginning of the line.

See the difference?

Reason: "delims=" means to remove the default delimiter, so the content on the line is copied down, while "tokens=*" means to get everything on the line, but ignores all the spaces at the beginning of the line.
