Question

I want to write a batch script that will copy an existing file repeatedly, gradually increasing the number in the file name of the copied file.

I have naively written this

for /l %%N in (1 5 500) do copy /y C:\batch\batch.pre C:\temp\g=0.00%%N

and have got no further. Would any of you intelligent chaps and chapesses put me on the right road?

Answer 1

The first file is named batch(1).pre, the second batch(2).pre, and so on, up to 500 files.

@echo off
for /l %%x in (1,1,500) do (
  copy C:\batch\batch.pre batch^(%%x^).pre
)
