answer aws s3 check if file exists

aws s3 check if file exists

Comment

Last time I saw performance comparisons getObjectMetadata was the fastest way to check if an object exists. Using the AWS cli that would be the head-object method, example:

aws s3api head-object --bucket www.codeengine.com --key index.html
which returns:

{
    "AcceptRanges": "bytes",
    "ContentType": "text/html; charset=utf-8",
    "LastModified": "Sun, 08 Jan 2017 22:49:19 GMT",
    "ContentLength": 38106,
    "ContentEncoding": "gzip",
    "ETag": "\"bda80810592763dcaa8627d44c2bf8bb\"",
    "StorageClass": "REDUCED_REDUNDANCY",
    "CacheControl": "no-cache, no-store",
    "Metadata": {}
}
