Description

« Hide

Assuming the dfs commands follow POSIX standards, there are some problems with the DFS du and dus commands. I compared the DFS output with that of RHEL 4u5

1. du a file/directory that does not exist:
Linux: du: cannot access `something': No such file or directory
DFS: Found 0 items

2. dus a file/directory that does not exist:

Linux: du: cannot access `something': No such file or directory
DFS: /something 0

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
