How can I download a file from an S3 bucket with wget?

You should be able to access it from a url created as follows:

http://{bucket-name}.s3.amazonaws.com/<path-to-file>

Now, say your s3 file path is:

s3://test-bucket/test-folder/test-file.txt

You should be able to wget this file with following url:

http://test-bucket.s3.amazonaws.com/test-folder/test-file.txt

1. Go to S3 console

2. Select your object

3. Click 'Object Actions'

4. Choose 'Download As'

5. Use your mouse right-click to 'Copy Link Address'

6. Then use the command:

   wget --no-check-certificate --no-proxy 'http://your_bucket.s3.amazonaws.com/your-copied-link-address.jpg'

AWS cli has a 'presign' command that one can use to get a temporary public URL to a private s3 resource.

aws s3 presign s3://private_resource

You can then use wget to download the resource using the presigned URL.
