delete_s3_object_golang

1. Run AWS CLI to save objects to results.json file

aws s3api list-objects --bucket <BUCKET_NAME> > results.json

2. The script will find older-than-28-day files which have extension .png, not .pdf and .csv, with an assumption that all files not having file extension are PNG files

go mod init
go mod tidy
go run main.go

3. Run go script with flag --dryrun=false to find the actual PNG files in the bucket and delete all PNG files

go run main.go --dryrun=false
