如何在命令行中创建循环？

Question

I tried this command

for /r %v in (*.abc) do abcconvert -toOgawa %v %v

and my result is :

E:\PROGRAMMES\HOUDINI\bin>abcconvert -toOgawa E:\PROGRAMMES\HOUDINI\bin\Mesh01_00009.abc E:\PROGRAMMES\HOUDINI\bin\ParticleMesh01_00009.abc
Error: inFile and outFile must not be the same!

I just wrote one loop but its the same answer for all my loops.

I think my loop is good but i don't know how to change the name of my outfile.. i would like exactly the same path but just newfile0001 then newfile0002 and so on.. for example

I try to do this because i have a lot of files to convert and the original command to do this is :

abcconvert -toOgawa file.abc newfile.abc

good news: your loop works good.
The problem is %v %v , which is the very same filename for input and output.
You have to change it somehow. See for /f near the end there are "modifiers".

There are many ways to change the output file name, many of them can be done just with those modifiers.

Simplest way: just change the extension:

for /r %v in (*.abc) do abcconvert -toOgawa %v %~dpnv.new

ParticleMesh01_000000.new

But you can also add a string to the filename (before the extension):

for /r %v in (*.abc) do abcconvert -toOgawa %v %~dpnv-new%~xv

ParticleMesh01_000000-new.abc
