Subject [jira] Commented: (HADOOP-662) dfs -ls sometime prints "Found xxx items"; sometimes it does not print that string
Date Mon, 18 Dec 2006 08:24:28 GMT
    [ http://issues.apache.org/jira/browse/HADOOP-662?page=comments#action_12459218 ] 
            
Jiang Lei commented on HADOOP-662:
----------------------------------

Yes, the ls command of unix print different format depends on the type of target. 
But I think if we can provide some option to fit the requirement of this user(if this kind
of requirement is general). 
If all think this is unnecessary, we can close the bug? :) thx.
