batch file to list filenames and copy its content-CodePudding

I need to copy content of all text files (more than 100) with their names in a file.

I know I can list names of files.

Dir  /b *.txt > Combine.txt

I can copy content of text files like it.

copy *.txt Combine.txt

But how to mix it?

I need Combine.txt

file1.txt
Content of file1 
file2.txt
Content of file2 
file3.txt
Content of file3 
file4.txt
Content of file4

CodePudding user response：

Whilst it may not actually look exactly as in your example, I'd suggest you give the following a try:

find /v "" *.txt > allcontent.log

And to do that more correctly:

%SystemRoot%\System32\find.exe /V "" "*.txt" 1>"allcontent.log"

The content would look a little more like this:

---------- FILE1.TXT
Content of file1 

---------- FILE2.TXT
Content of file2 

---------- FILE3.TXT
Content of file3 

---------- FILE4.TXT
Content of file4

As a side note, I changed the destination filename to use a .log extension, to not have the results try to include its own content, (which would have happened had it also included the .txt extension).

CodePudding user response：

del 2>nul "output.xxx"&(for %J in (*.txt) do @>>output.xxx (echo %J&type "%J"))&move /y "output.xxx" "output.txt" >nul

from the prompt.

Since the output filename matches the mask *.txt, you need to generate the intermediate filename to a non-maskmatching name.

You may need to delete output.txt first to avoid including the original contents of that file in the result file.
