Downloading Shared Files on Google Drive Using Curl

Downloading Shared Files on Google Drive Using Curl

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.

File size < 40MB

CURL

filename="### filename ###"
fileid="### file ID ###"
curl -L -o ${filename} "https://drive.google.com/uc?export=download&id=${fileid}"

File size > 40MB

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&amp;confirm=####&amp;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.

CURL

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.

sample script

This is a simple bash script.

#!/bin/bash
fileid="### file id ###"
filename="MyFile.csv"
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}

CLI tool

If you will use a CLI tool, please use this. This is a CLI tool to download shared files and folders from Google Drive. For large file, the resumable download can be also run.

Updated at February 17, 2022

Recently, it seems that the specification of this flow has been changed. So I updated this answer. In order to download a publicly shared file of large size from Google Drive, you can use the following script.

#!/bin/bash
fileid="### file id ###"
filename="MyFile.csv"
html=`curl -c ./cookie -s -L "https://drive.google.com/uc?export=download&id=${fileid}"`
curl -Lb ./cookie "https://drive.google.com/uc?export=download&`echo ${html}|grep -Po '(confirm=[a-zA-Z0-9\-_]+)'`&id=${fileid}" -o ${filename}
  • In this case, the ID for downloading is retrieved from the HTML data as follows.

      <form id="downloadForm" action="https://drive.google.com/uc?export=download&amp;id={fileId}&amp;confirm={value for downloading}" method="post">
    
  • When you want to download a publicly shared file of small size from Google Drive, you can use the following command.

      curl -L "https://drive.google.com/uc?export=download&id=### fileId ###" -o sampleoutput.csv
    
  • Also, goodls was updated to v1.2.8.

Testing

  • August 3, 2022: I could confirm that the method on February 17, 2022, can be still available.

@Green-cattow
Thank you for your comment. At windows, it seems that both -Po and -Eio can be used.

Unfortunately, I cannote replicate your grep invalid range. When I tested my proposed script again, I confirmed that no error occurs. I deeply apologize for this.

For example, curl -s -L 'https://drive.google.com/uc?export=download&id={fileId}' | grep -Po '(confirm=[a-zA-Z0-9\-_]+)' returns confirm=###.

regex for character class says - must be added to last or first if itwas litereal for matching because in middle it acts as a range

Hello, I'm running into a weird issue where it doesn't actually download the file: seems like quota issues or something.
