How to remove spaces in filenames on s3 bucket programmatically using boto with python?

Question

so I have 1000s of files on my s3 bucket. But, the names of the files contain spaces. I want to replace the space with '_' programmatically using boto python. How do I achieve this?

Thanks.

It is not possible to rename objects in Amazon S3.

Instead, you would need to call CopyObject() to copy the object, and then DeleteObject() to delete the original object.

Alternatively, here's a cheating method that I use:

• I create an Excel spreadsheet with the name of the files
• Then, in Column B, I create a formula to convert the spaces into underlines, so it contains the desired name
• In Column C, I write a command that renames the object, like this:

="aws s3 mv 's3://bucketname/"&A1&"' s3://bucketname/"&B1

• Test the command by pasting it into a terminal window
• If it works, use Copy Down to create the formula for all of the files
• Copy that column, paste it into a .sh file, then run the file (preferably on an Amazon EC2 instance to reduce network latency)

The AWS CLI aws s3 mv command will call CopyObject() and DeleteObject().
