Command syntax

 ./ossutil appendfromfile local_file_name oss://bucket/object [--meta=meta-value] [--payer requester] 
If the appendable object does not exist, you can use the --meta option to configure the object metadata, such as --meta "X-Oss-Meta-Author:test". The --meta option cannot be used to append content to an object that already exists.
Notice
  • You must specify the name for objects uploaded using append upload.
  • You can only append content to objects created using append upload.
  • You can use the set-meta command to modify the metadata of an object.
