Can anyone explain what is happening here

[Sounak@9434]

So guys I was playing around with batch macros and and am going to write a small topic about it at http://www.thebateam.org.

I was looking at almost all of my code but, I can't really make out what's happening in this common line.

Code: Select all

set ^"\n=^^^%LF%%LF%^%LF%%LF%^^"

I know %LF% is a newline character(0x0A). But how can this line issue a newline with line continuation?

Can anyone write a step by step guide on what is happening here. Thanks in advance.

Sincerely,
Sounak

Thankfully, you're on the site that invented that line.

Jeb may have explained it at some point before that post, but that's the earliest one I can find.

Hello All!

In 2008, a Stack Overflow user asked how to echo a newline in Batch files. Someone called Ken posted this answer. This prompted a request for an explanation of how the code worked, but Ken was unforthcoming. So Jeb took up the slack and provided this now famous answer… two and a half years later?

HTH!

@ShadowThief:, @SpongeBelly:

Thanks to both of you. I think I might have understood it.

set ^"\n=^^^%LF%%LF%^%LF%%LF%^^"
set \n=^%LF%%LF%^

So it creates an escaped linefeed with an caret at the end. Thanks
