Skipping variable looks impossible

So I want to Echo %%a into another txt file, but seems nothing works to me. Here's the code :

for /f "delims=" %%a in ( 
'dir "*.txt" /b /s /a-d' 
) do Echo for /f "delims=" %%a in ^( >> "%%a"

Simple : output file looks like:

"for /f "delims=" C:\Documents and Settings\xxxxx\Desktop\alpha\lol.txt in ( " .

I just need not a full path but "%%a". Bat file.

As you saw, it's not directly possible to escape the %%a expression in a loop.

But like Magoo mention, it can be solved with changing the loop parameter.

You could also use the parser to create the %%a output.

setlocal EnableDelayedExpansion
set "static=for /f "delims=" %%%%a in ("
for /f "delims=" %%a in ( 'dir "*.txt" /b /s /a-d') do (
  echo !static! >> "%%a"
)

The content of the variable static will be expanded, but the inner %%a will not expanded later.

You want the literal %%a ?

Try %%%%a

Second suggestion:

Try %%%%^a

Third - change the metavariable (loop-control variable) to %%b

for /f "delims=" %%b in ( 
'dir "*.txt" /b /s /a-d' 
) do Echo for /f "delims=" %%%%a in ^( >> "%%b"

Try this:

 for /f "delims=" %%a in ('dir "*.txt" /b /s /a-d' ) do Echo %%a >> output.txt
