rman command

1.
what is the different between
list copy and
list copy of databas archivelog all


2.
what is the different between
list backup and
list backup of database archivelog all

list copy would only list the backup copies of the tablespaces and datafiles and controlfile copies. Where as the list copy archivelog would list only the archivelog backup information. Where as you wouldn't see it under the first command.
