Date Sat, 23 Feb 2008 01:15:20 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-2219?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12571672#action_12571672
] 

Tsz Wo (Nicholas), SZE commented on HADOOP-2219:
------------------------------------------------

Instead of adding a option, how about changing the output as followings?
{code}
bash-3.2$ ./bin/hadoop fs -du /
Found 3 items
              byte         file directory
               159            1         0   hdfs://host:9000/a.txt
             44198            1         0   hdfs://host:9000/build.xml
               318            2         2   hdfs://host:9000/user
bash-3.2$ ./bin/hadoop fs -dus /
             44675            4         3   /

>             Project: Hadoop Core

> To keep the total number of files on dfs low, we like the users to be able to easily
find out how many files each of their directory contain.   
> Currently, we only have fsck or dfs -lsr which takes time.
> Can I ask for an option for du to show the total number of files (as well as the total
size) of a given directory?
