Amazon S3 boto: How do you rename a file in a bucket?

Question

How do you rename a S3 key in a bucket with boto?

Answer 1

You can't rename files in Amazon S3. You can copy them with a new name, then delete the original, but there's no proper rename function.

Answer 2

Here is an example of a Python function that will copy an S3 object using Boto 2:

import boto  def copy_object(src_bucket_name,                 src_key_name,                 dst_bucket_name,                 dst_key_name,                 metadata=None,                 preserve_acl=True):     """     Copy an existing object to another location.      src_bucket_name   Bucket containing the existing object.     src_key_name      Name of the existing object.     dst_bucket_name   Bucket to which the object is being copied.     dst_key_name      The name of the new object.     metadata          A dict containing new metadata that you want                       to associate with this object.  If this is None                       the metadata of the original object will be                       copied to the new object.     preserve_acl      If True, the ACL from the original object                       will be copied to the new object.  If False                       the new object will have the default ACL.     """     s3 = boto.connect_s3()     bucket = s3.lookup(src_bucket_name)      # Lookup the existing object in S3     key = bucket.lookup(src_key_name)      # Copy the key back on to itself, with new metadata     return key.copy(dst_bucket_name, dst_key_name,                     metadata=metadata, preserve_acl=preserve_acl)
