Removing a token with an obscure trick

[jeb]

Hi,

I know this trick for a long time, but I can't found any useful application for it.

But perhaps have anyone else an use case.

Code: Select all

@echo off
echo One two three ^
four

echo One two three^
 four

echo One two<nul three ^
four

echo One two<nul three^
 four

One two three four
One two three four
One two three four
One two four

As you can see in the fourth line the word/token "three" is removed, this is an effect of the redirection and a token just before a multiline caret.
This effect is not related to the ECHO, it works always.

It can strip a single token from a string like here

Code: Select all

set var=one two <nul "this & that"^
three
set var

one two three

But currently I didn't know what problem can be benefit by this

Maybe it could be used for commenting-out things in a weird way?
