How to download in bulky compressed (zip, 7z, bzip, xz, etc) archive files from a repository automatically by use of wget ?
wget http://path/to/file.gz
I think he means multiple files.
If so, you can use a for loop and use wget and iterate over files.
wget -nd -r -P /local/folder -A zip,7z,bzip,xz http://www.website.com
