> Assuming the dfs commands follow POSIX standards, there are some problems with the DFS
ls  and lsr commands. I compared the DFS output with that of RHEL 4u5
> 1. ls a directory when there are no files/directories in that directory:
> Linux: No output
> DFS: Found 0 items
> 2. ls a file/directory that does not exist:
> Linux: ls: /doesnotexist: No such file or directory
> DFS: Found 0 items
> 3. lsr a directory that does not exist:
> Linux: ls: /doesnotexist: No such file or directory
> DFS: No output
