When the shared files on Google Drive is downloaded, it is necessary to change the download method by the file size. The boundary of file size when the method is changed is about 40MB.
filename="### filename ###"
fileid="### file ID ###"
curl -L -o ${filename} "https://drive.google.com/uc?export=download&id=${fileid}"When it tries to download the file with more than 40MB, Google says to download from following URL.
<a id="uc-download-link" class="goog-inline-block jfk-button jfk-button-action" href="/uc?export=download&confirm=####&id=### file ID ###">download</a>Query included confirm=#### is important for downloading the files with large size. In order to retrieve the query from the HTML, it uses pup.
pup 'a#uc-download-link attr{href}'And sed is used to remove amp;.
sed -e 's/amp;//g'`So curl command is as follows.
filename="### filename ###"
fileid="### file ID ###"
query=`curl -c ./cookie.txt -s -L "https://drive.google.com/uc?export=download&id=${fileid}" | pup 'a#uc-download-link attr{href}' | sed -e 's/amp;//g'`
curl -b ./cookie.txt -L -o ${filename} "https://drive.google.com${query}"The value of confirm is changed every time. So when the value of confirm is retrieved, the cookie is saved using -c ./cookie.txt, and when the file is downloaded, the cookie has to be read using -b ./cookie.txt.
By using this method, you can download files with the size of over 1 GB.

This is a simple bash script.
#!/bin/bash
fileid="### file id ###"

curl -c ./cookie -s -L "https://drive.google.com/uc?export=download&id=${fileid}" > /dev/null
curl -Lb ./cookie "https://drive.google.com/uc?export=download&confirm=`awk '/download/ {print $NF}' ./cookie`&id=${fileid}" -o ${filename}If you will use a CLI tool, please use this.
