China DOS Union

When we use del, it has a /S parameter that can operate on all subdirectories~
But going the other way around, if I want to copy a file (say dos.txt) into all subdirectories of some partition, how should I do it?
copy doesn't provide a /S parameter either :(

Search ;

This kind of question has been discussed way too many times

The OP can try thinking about it like this:
Use dir's /s parameter together with a for loop.

That really is correct, thank you very much indeed! I'd like to ask, what exactly does ^ do here?

for's /r and /d commands seem to have been ignored for a long time, extra points, extra points

^ means that the following " is an ordinary character, not a symbol in the command

Then wouldn't it become copy dos.txt ""?
I still don't quite understand how in specifies the folders here...?

Because the value of %%i is a path with an extra " added at the end, for example d:\aa\bb\"
So "%%i becomes "d:\aa\bb\"

Looks like it's my fault for not making myself clear, I do understand this part. What I mean is...
Inside (^"), does ^ have any meaning besides indicating that what follows is an ordinary symbol?
I checked the usage of for /r, and it says that if the set contains only a single dot character, then it enumerates the directory tree~
So in this case, is ^ the so-called single dot character?
What exactly does single dot character mean?

No, I think that "single dot" means when it's empty; the wording in the help command really is quite confusing.

Oh~~~ if that's the case then it's easy to understand
Anyway, that "single dot character" in the help file really had me completely baffled!!!

The more you read the help, the more confused you get. You can only look at examples.

Learning this, good stuff.
