下面的示例对上一示例进行了扩展，显示了其工作方式。
// Delete local file
$ rm ./MyFile1.txt
// Attempt sync without --delete option - nothing happens
$ aws s3 sync . s3://my-bucket/path
// Sync with deletion - object is deleted from bucket
$ aws s3 sync . s3://my-bucket/path --delete
delete: s3://my-bucket/path/MyFile1.txt
// Delete object from bucket
$ aws s3 rm s3://my-bucket/path/MySubdirectory/MyFile3.txt
delete: s3://my-bucket/path/MySubdirectory/MyFile3.txt
// Sync with deletion - local file is deleted
$ aws s3 sync s3://my-bucket/path . --delete
delete: MySubdirectory\MyFile3.txt
// Sync with Infrequent Access storage class
$ aws s3 sync . s3://my-bucket/path --storage-class STANDARD_IA
使用 --exclude 和 --include 选项可以指定规则来筛选要在同步操作期间复制的文件或对象。默认情况下，指定目录中的所有项都包含在同步中。因此，仅当指定 --exclude 选项的例外情况（例如，–include 实际上意味着“不排除”）时才需要使用 --include。这些选项按指定顺序应用，如下例所示。
Local directory contains 3 files:
MyFile1.txt
MyFile2.rtf
MyFile88.txt
'''
$ aws s3 sync . s3://my-bucket/path --exclude '*.txt'
upload: MyFile2.rtf to s3://my-bucket/path/MyFile2.rtf
'''
$ aws s3 sync . s3://my-bucket/path --exclude '*.txt' --include 'MyFile*.txt'
upload: MyFile1.txt to s3://my-bucket/path/MyFile1.txt
upload: MyFile88.txt to s3://my-bucket/path/MyFile88.txt
upload: MyFile2.rtf to s3://my-bucket/path/MyFile2.rtf
'''
$ aws s3 sync . s3://my-bucket/path --exclude '*.txt' --include 'MyFile*.txt' --exclude 'MyFile?.txt'
upload: MyFile2.rtf to s3://my-bucket/path/MyFile2.rtf
upload: MyFile88.txt to s3://my-bucket/path/MyFile88.txt
–exclude 和 --include 选项也可以与 --delete 选项一起使用来筛选要在同步操作期间删除的文件或对象。在这种情况下，参数字符串必须指定要在目标目录或存储桶上下文中包含或排除在删除操作中的文件。下面是一个示例。
Assume local directory and s3://my-bucket/path currently in sync and each contains 3 files:
MyFile1.txt
MyFile2.rtf
MyFile88.txt
'''
// Delete local .txt files
$ rm *.txt
// Sync with delete, excluding files that match a pattern. MyFile88.txt is deleted, while remote MyFile1.txt is not.
$ aws s3 sync . s3://my-bucket/path --delete --exclude 'my-bucket/path/MyFile?.txt'
delete: s3://my-bucket/path/MyFile88.txt
'''
// Delete MyFile2.rtf
$ aws s3 rm s3://my-bucket/path/MyFile2.rtf
// Sync with delete, excluding MyFile2.rtf - local file is NOT deleted
$ aws s3 sync s3://my-bucket/path . --delete --exclude './MyFile2.rtf'
download: s3://my-bucket/path/MyFile1.txt to MyFile1.txt
'''
// Sync with delete, local copy of MyFile2.rtf is deleted
$ aws s3 sync s3://my-bucket/path . --delete
delete: MyFile2.rtf
sync 命令还可以接受 --acl 选项，使用该选项可以设置对复制到 Amazon S3 中的文件的访问权限。该选项接受 private、public-read 和 public-read-write 值。
$ aws s3 sync . s3://my-bucket/path --acl public-read |
