Limiting Powershell Get-ChildItem by File Creation Date Range

问题

I use a Powershell command to generate a CSV report of certain file types. My goal is to find out how many were added during a particular date range. Right now, the script finds everything and I sort by date to find my number. I'd like to modify the command to only return objects within a creation date rage, i.e. if this file was created between 1 March 2013 and 31 March 2013. There's probably a way to limit the command by a date range, likely using Select-Object, I just can't figure it out.

Get-ChildItem 'PATH' -recurse -include @("*.tif*","*.jp2","*.pdf") | Select-Object FullName, CreationTime, @{Name="Mbytes";Expression={$_.Length/1Kb}}, @{Name="Age";Expression={(((Get-Date) - $_.CreationTime).Days)}} | Export-Csv 'PATH\scans.csv'

回答1:

Use Where-Object and test the $_.CreationTime:

Get-ChildItem 'PATH' -recurse -include @("*.tif*","*.jp2","*.pdf") | 
    Where-Object { $_.CreationTime -ge "03/01/2013" -and $_.CreationTime -le "03/31/2013" }

Use Where-Object, like:

Get-ChildItem 'PATH' -recurse -include @("*.tif*","*.jp2","*.pdf") | 
Where-Object { $_.CreationTime -gt "03/01/2013" -and $_.CreationTime -lt "03/31/2013" }
Select-Object FullName, CreationTime, @{Name="Mbytes";Expression={$_.Length/1Kb}}, @{Name="Age";Expression={(((Get-Date) - $_.CreationTime).Days)}} | 
Export-Csv 'PATH\scans.csv'

Fixed it...

Get-ChildItem C:\Windows\ -recurse -include @("*.txt*","*.pdf") |
Where-Object {$_.CreationTime -gt "01/01/2013" -and $_.CreationTime -lt "12/02/2014"} | 
Select-Object FullName, CreationTime, @{Name="Mbytes";Expression={$_.Length/1Kb}}, @{Name="Age";Expression={(((Get-Date) - $_.CreationTime).Days)}} | 
Export-Csv C:\search_TXT-and-PDF_files_01012013-to-12022014_sort.txt
