Description

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
