How do I properly set wget to download only new files?
Solution 1:
did you read this ? http://www.editcorp.com/Personal/Lars_Appel/wget/wget_5.html
"Several days later, you would like Wget to check if the remote file has changed, and download it if it has."
wget -N http://www.some-url.com/folder/
Try this.
Solution 2:
wget -c
also continues partial files caused when the download has issues.....
Better yet,
wget -c -N
seems to do both at the same time.
