Question

I am trying to put these two scripts together:

This one lists all the files in all the directories:

dir -recurse | group-object Extension -noelement

And this one lists all the files that were modified after a certain date:

get-childitem –recurse | where-object {$_.lastwritetime -gt “1/13/2008”}

My issue is that the second script outputs a header for every directory:

Mode                LastWriteTime     Length Name                                                                      
----                -------------     ------ ----                                                                      
d----        12/10/2012  11:21 AM            BUDGET                                                                    
d----        12/21/2012  12:38 PM            SPEND DOWN                                                                


    Directory: \\file\property\vt\Environmental Services\BUDGET\SPEND DOWN


Mode                LastWriteTime     Length Name                                                                      
----                -------------     ------ ----                                                                      
d----        12/13/2012  12:32 PM            2012                                                                      
d----         1/29/2013   9:50 AM            2013                                                                      


    Directory: \\le\property\vt\Environmental Services\BUDGET\SPEND DOWN\2012

I tried to put them together like this:

dir -recurse | group-object Extension -noelement | where-object {$_.lastwritetime -gt (Get-date).AddDays($somenumber)}

But this did not yield any results.

How can I list the counts of all the different types of files since a certain day recursively in all directories?

Here’s my expected output:

4352    .JPG
2352    .doc
2135    .pdf
1811    .xls
1472

63  .ppt
61  .url

Answer 1

dir and gci are both aliases for the Get-ChildItem cmdLet. Just filter before grouping:

gci -Recurse| where {$_.LastWriteTime -gt (Get-Date).AddDays(-45)}| group Extension -NoElement
