如何删除超过x天的数据。在linux hdfs非常简单，但hdfs dfs -ls /<path>找不到。
此外，即使Sub SomeSub()
Dim StartWord As String, EndWord As String
Dim Find1stRange As Range, FindEndRange As Range
Dim DelRange As Range, DelStartRange As Range, DelEndRange As Range
'Setting up the Ranges
Set Find1stRange = ActiveDocument.Range
Set FindEndRange = ActiveDocument.Range
Set DelRange = ActiveDocument.Range
'Set your Start and End Find words here to cleanup the script
StartWord = "From: Research.TA@traditionanalytics.com"
EndWord = "This message has been scanned "
'Starting the Find First Word
With Find1stRange.Find
.Text = StartWord
.Replacement.Text = ""
.Forward = True
.Wrap = wdFindAsk
.Format = False
.MatchCase = False
.MatchWholeWord = False
.MatchWildcards = False
.MatchSoundsLike = False
.MatchAllWordForms = False
'Execute the Find
Do While .Execute
'If Found then do extra script
If .Found = True Then
'Setting the Found range to the DelStartRange
Set DelStartRange = Find1stRange
'Having these Selections during testing is benificial to test your script
DelStartRange.Select
'Setting the FindEndRange up for the remainder of the document form the end of the StartWord
FindEndRange.Start = DelStartRange.End
FindEndRange.End = ActiveDocument.Content.End
'Having these Selections during testing is benificial to test your script
FindEndRange.Select
'Setting the Find to look for the End Word
With FindEndRange.Find
.Text = EndWord
.Execute
'If Found then do extra script
If .Found = True Then
'Setting the Found range to the DelEndRange
Set DelEndRange = FindEndRange
'Having these Selections during testing is benificial to test your script
DelEndRange.Select
End If
End With
'Selecting the delete range
DelRange.Start = DelStartRange.Start
DelRange.End = DelEndRange.End
'Having these Selections during testing is benificial to test your script
DelRange.Select
'Remove comment to actually delete
'DelRange.Delete
End If 'Ending the If Find1stRange .Found = True

End With 'Ending the Find1stRange.Find With Statement
End Sub
也会提供未排序的有序数据。

以下是执行此操作的代码段：
days_diff=10
now=$(date +%s)
hdfs dfs -ls /path/todir/ | while read f; do
dir_date=`echo $f | awk '{print $6}'`
filename=`echo $f | awk '{print $8}'`
difference=$(( ( $now - $(date -d "$dir_date" +%s) ) / (24 * 60 * 60 ) ))
if [ $difference -gt $days_diff ]; then
echo "Deleting file:" $filename ;
hdfs dfs -rm $filename;
fi
done
