I want to copy the same file dozens of times in the same directory. How do I do this? Could someone tell me?

Is the question too newbie-level, so nobody wants to answer?

Put your file in one directory, for example: C:\test\ ， and move y into the C:\test\ directory
Run this command any number of times: for %a in (*) do @copy /y bbb b%a
Or write this command into a BAT like this:
@echo off
cd c:\test\
for %a in (*) do @copy /y bbb b%a
0%


Then run the BAT batch file.

I tried it, it doesn't work.

Run this command any number of times: for %a in (*) do @copy /y bbb b%a

There may be a problem with the batch file. I'm a newbie just like you too. Waiting for an expert to correct it.
With only a little superficial knowledge, I still try my best to help people.. Hope you understand.

Haha, got it working.
Change this
@echo off
cd c:\test\
for %a in (*) do @copy /y bbb b%a
0%
change %a to %%a, and don't use the @ symbol

@echo off
cd c:\test\
for %%a in (*) do copy /y bbb b%%a
0%
and it works, but it can only copy once.

I just looked up a lot of materials, it should be written like this:
for /l %%a in (1,1,500) do copy a.txt a%%a.txt
That can copy it as many times as you want. If you want to copy it more or fewer times, just change that 500 to the number you want.
Thanks for your reply anyway.

It depends on what you actually need, there are still many ways to write it,
set /a a=0
set /a v=10
:test
set /a a=a+1
copy %0 %a%.bat
if %a% GEQ %v% goto :eof
goto :test

pause

Thanks for the pointers.

copy %0 %random%.bat
start %0

And that's how an evil piece of code is born

Learned something, good stuff, thanks!
