> 1. The FSShell commands CreateSnapshot/DeleteSnapshot/RenameSnapshot currently may output
duplicated error msg. E.g., when trying to create snapshot on a file, we have the following
error msg:
> {noformat}
> createSnapshot: `/newFile': Is not a directory
> createSnapshot: `/newFile': Is not a directory
> {noformat}
> 2. deleteSnapshot/renameSnapshot with incorrect args does not throw usage msg.
