Thinking about Code

I needed to find a file that was created in March 2009.  The folder isn’t indexed so I created this PowerShell script to help find the files within a specified date range.

 

childitem -filter *.doc? -recurse |
    where {$_.CreationTime -gt
    [datetime]::parse("03/01/2009") -and
  $_.CreationTime -lt
    [datetime]::parse("03/31/2009") -and
        $_.length -gt 50}

 

The first line recursively finds all files with a doc or docx extension.

childitem -filter *.doc? -recurse | 

Lines 2-3 look for a file with a creation time greater than (-gt) March 1st 2009.

where {$_.CreationTime -gt
[datetime]::parse("03/01/2009") -and 

Lines 4-5 look for a file with a creation time less than (-lt)  March 31st 2009.

$_.CreationTime -lt
  [datetime]::parse("03/31/2009") -and 

And the final line looks for files larger that 50 bytes.

$_.length -gt 50}
