Push all the files in a directory to an s3 bucket

UPDATE: Of course, as soon as I hit publish, a coworker mentions that s3cmd has this functionality built in (and more!) including md5 + filesize checking so it doesn't push files that are already in s3. Check out the s3cmd sync command.


Say you've got a bunch of files sitting on a web server and you'd like to push them all to a bucket on s3. Maybe you want to set this up as a cron task so that the bucket is updated, say, every night.

find . -type f | sed 's|^./||g' | xargs -I {} s3cmd put {} s3://<REPLACE BUCKET NAME HERE>/{}

The find command lists all of the files recursively that are nested somewhere inside the current directory. Then we use sed to replace all of the ./ at the beginning of the file's paths so that we don't create an extra directory called . at the top of our s3 bucket.

Then we use xargs to run the s3cmd put command against each of the files' names. We're using the -I {} placeholder syntax that I learned earlier this week.

s3cmd is a great little utility. Directions for installing s3cmd are here.

Say Thanks
