------------------------------------------------

> Can we use Trash if it's enabled ? 

+1  I think this is a good idea.  It can be done by re-using the codes in 
FsShell.

> DistCp should support an option for deleting non-existing files.

> One use case of DistCp is to sync two directories.  Currently, DistCp has an 
> -update option for overwriting dst files if src is different from dst.  
> However, it is not enough for sync.  If there are some files in dst but not 
> exist in src, there is no easy way to delete them.  We should add a new 
> option, say -delete, so that DistCp will delete the non-existing in dst.
