wget不必要地下载index.html并暂停批处理脚本（Windows）

Question

I am having trouble with wget64 on Windows :

@echo OFF
FOR /L %%i in (1, 1, 9999) DO (
cls
echo Downloading file %%i
wget64.exe -e robots=off --progress=bar --show-progress -r -np -nd -nc -HDfilepi.com --content-disposition -a wget.log ebooks.info/book/%%i/
)

wget will download index.html (which I feel is unnecessary), then it proceeds to the hosted file and downloads it if the file does not exist on the destination, but will fail to retrieve the index.html of the next book and start the next download.

Is it really necessary to download index.html and if that is the case, how can I tell wget to erase and download the new one every time?

Disclaimer: I am only asking about the specific behaviour of wget, I am not asking to help in the download script nor do I condone illegally downloading files.

Answer 1

I think you may be overthinking this. Assuming that all the other files wget is retrieving are the correct ones, since you're using a FOR loop anyway, why not just delete index.html on each iteration like so:

@echo OFF
FOR /L %%i in (1, 1, 9999) DO (
cls
echo Downloading file %%i
wget64.exe -e robots=off --progress=bar --show-progress -r -np -nd -nc -HDfilepi.com --content-disposition -a wget.log ebooks.info/book/%%i/
if exist index.html del index.html
)
