amazon s3 - Downloading from S3 with aws-cli using filter on specific prefix -


for reason there's bucket bunch of different files, of have same prefix different dates:

backup.2017-01-01aa

backup.2017-01-01ab

backup.2017-01-15aa

backup.2017-01-15ab

backup.2017-02-01aa

backup.2017-02-01ab

etc..

how download only files start "backup.2017-01-01"?

you'll have use aws s3 sync s3://yourbucket/

there 2 commands can give aws s3 sync; --exclude , --include, both of can take "*" wildcard.

first we'll have --exclude "*" exclude of files, , we'll --include "backup.2017-01-01*" include files want specific prefix. can change include around --include "*-01-01*".

that's it, here's full command:

aws s3 sync s3://yourbucket/ . --exclude "*" --include "backup.2017-01-01*"

also, remember use --dryrun test command , avoid downloading files in bucket.
