How can I change all existing objects in my bucket to public or private using s3cmd or Cyberduck?

Using s3cmd

To recursively set all objects in your bucket to public, the s3cmd tool can be used:

https://www.linode.com/docs/guides/how-to-use-object-storage/#s3cmd

After installing and configuring, use the following command to set all objects to public:

s3cmd setacl s3://bucketname --acl-public --recursive

Alternatively, all objects in the bucket can be set to private using this command:

s3cmd setacl s3://bucketname --acl-private --recursive

Using Cyberduck

This can also be done through Cyberduck.

  • Click on the first object in the bucket
  • Scroll to the last object in the bucket, Shift + click to highlight and select all the objects
  • Click the system wheel at the top, then click 'Info'
  • If 'Everyone' is listed under 'grantee', click the setting to the right, then change to 'Read'. This will change the permissions for all objects selected.
  • If 'Everyone' is not listed, click the system wheel at the bottom, then click 'Everyone' to add it. Then follow the previous step to change all objects to have 'Read' permissions.
