Question

I need to echo url with get-parameters to a text file.

When I am trying:

set url=text=2
echo %url% > file.txt

the result is almost ok:

text=2 

But there is one space after number 2 which is not needed

If I try to remove that space from code:

set url=text=2
echo %url%> file.txt

but the result is just empty!

Is it possible to echo "text=2" without space at the end?

PS url in real code is actually like this:

set url=%~1

Answer 1

Two solutions

(echo %url%) >file

>file echo %url%

Your problem is the single number before the redirection is treated as stream number.

It's parsed as echo text= 2> file , it tries to redirect only the stream2/stderr to the file now
