copying files between s3 buckets without folders amazon aws cli

Question

I'm looking through the documentation of aws cli and I cannot find the way to copy the only files in some directory structure to other bucket with "flattened" structure(I want one directory and all files inside of it).

for example

/a/b/c/1.pg
/a/2.jpg
/a/b/3.jpg

i would want to have in different bucket:

/x/1.jpg
/x/2.jpg
/x/3.jpg

Am I missing something or is it impossible? Do you have an idea how could I do that?

Answer 1

Assuming that you have aws cli configured on the system and assuming that both the buckets are in the same region. What you can do is first dowload the s3 bucket to your local machine using:

aws s3 sync s3://originbucket /localdir/

Post this, use a find command to get all the files into one dir

find /localdir/ -type f -exec mv {} /anotherlocaldir/

Finally, you can upload the files to s3 again!

aws s3 sync /anotherlocaldir/ s3://destinationbucket
