How to Download from Archive.org Without the Browser
Three good options to download from archive.org without a browser, in increasing order of capability.
wget
Available on every Unix system. Works fine for direct files — use wget -c followed by the full download URL. The -c flag resumes partial downloads. For grabbing a whole item as one file, point it at the auto-generated ZIP at https://archive.org/compress/IDENTIFIER. To recursively download every file inside an item without the ZIP wrapping, use wget -r -np -nH --cut-dirs=2 followed by the item's download directory URL. The -np flag keeps wget from climbing back up the directory tree.
curl
Works similarly. The flag for resume is -C - — run curl -C - -O followed by the download URL.
The ia tool
The Archive's own client, and the best choice if you are going to do this more than once or twice. It is faster than wget for large items, handles retries gracefully, supports format filters, and integrates with the Archive's search API. Install with pip install internetarchive, then run ia download IDENTIFIER.
For pulling many items, only the ia tool is realistic. wget can do it with shell loops, but you will write more code than the gain is worth.
URL patterns
Every archive.org file URL follows the pattern https://archive.org/download/IDENTIFIER/FILENAME. You can construct these directly if you know what you are after. The full file list for an item lives at the download URL with just the identifier (a directory listing), or as XML at the same path with IDENTIFIER_files.xml appended.
The command-line tools handle the downloading, but the discovery step — figuring out which items and files you actually want — is where Arkibber fits in. Search, filter by media type and date, and identify the right items before you queue up your downloads.
