> The FsShell commands are very tightly coupled together which makes it necessarily hard to write new commands.  There is a lot of redundancy between the commands, inconsistencies in handling of paths, handling of errors, and correct return of exit codes.  The FsShell commands should be subclasses of the fs.shell.Command class which is already being used by the -count command, and is used by other commands like dfsadmin.
> This will serve as an umbrella bug to track the changes.
