Start the Windows PowerShell ISE.
2. Use the Get-Verb cmdlet to obtain a listing of approved verbs.
3. From the list of verbs outputted from #2, select a verb that would be appropriate for a
function that obtains a listing of files by date last modified.
4. Create a new function named Get-FilesByDate.
5. Add four command-line parameters to the function. The first parameter is an array of file
types, the second is for the month, the third parameter is for the year, and the last parameter is
an array of file paths.
6. Add the code to perform a recursive search of paths supplied via the $path variable. Limit
the search to include only file types supplied via the $filetypes variable.

Add a Where-Object clause to limit the files returned to the month of the
lastwritetime property that equals the month supplied via the command line, and the
year supplied via the command line.
Save the function in a .ps1 file named Get-FilesByDate.ps1.
Add to the script containing the function the commands required to call the function,
searching for:
.docx files, from Month 2, year 2020, in path c:\Users
(I didn’t have any .docx files from that month, so I used month = 3, then created an empty file in
my documents directory with name “test.docx”)

Were happy to HELP but not a script writing service. What have you tried? Where are you stuck?

It seems pretty straight forward, give it a try, if you get stuck or have questions, feels free to post the code you have tried and we’ll try to help

If you post code, please use the ‘Insert Code’ button. Please and thank you!

PLEASE READ BEFORE POSTING! Read if you're new to the PowerShell forum! Programming & Development

Hi, and welcome to the PowerShell forum! Don’t apologize for being a “noob” or “newbie” or “n00b.” There’s just no need – nobody will think you’re stupid, and the forums are all about asking questions. Just ask! Use a descriptive subject. Don’t say “Need help” or “PowerShell Help”, actually summarize what the problem is. It helps the rest of us keep track of which problem is which. Don’t post massive scripts. We’re all volunteers and we don’t have time to read all that, nor will we copy…

We’re also not a homework answering service. Happy to help if you need some general pointers, or you’ve got some code and you can’t quite get it to work.

To give you some ideas where to go however, you should look into Get-ChildItem. You can see examples of what it does using Get-Help or just googling it. You’re going to need a loop to go through the items that Get-ChildItem returns. Items returned do have a lastwritetime and that can be further broken down into Day,Month,Year, so if you had an item from Get-ChildItem you could look at the $item.LastWriteTime.month for example to do a comparison on the month. There is a recursive option for Get-ChildItem. If you’ve been doing Powershell for a while you should be able to find that easily.

You’re going to need a loop to go through the items that Get-ChildItem. According to #5 you could have multiple file paths, so you’re going to need a loop to go through those as well. That means you will have nested loops.

If you type dir in powershell, that’s an alias for Get-ChildItem so you know what it does, even if you didn’t know dir was actually calling that. You may already be fully familiar with that command, but we can’t tell your level of experience from the initial post which is why I’m pointing you that way.

actually i am new to this power shell so thats the reason i am totally confused with this question 5 and 6

Well you could be feeding it multiple file paths when you call the function such as c:, c:\temp. When you define a function, you can define multiple parameters such as the path, the file types, the month, day. Here’s a quick function. All it’s going to do is basically give you a directory on all of the paths you feed it. In your case, you’re going to have 4 parameters defined instead of one. When you call the function you will be specifying 4 options instead of 1 on the command line. Dirlist is the parameter I defined. It could be called PathList or whatever you want to call it. I made it mandatory, so that if you were to just type Get-Dirs, it’s going to come back and ask you to supply that parameter. If the parameter is optional it can be left out. In your case, you probably want them all to be mandatory. For #6 it’s saying that you should be checking all sub directories under the path you provide. That’s easy enough. Get-ChildItem has the ability to recurse. It also has the ability to only include certain types of files. Look at the help for it and look at the parameters it accepts. If you read through the list you’ll find the ones I’m referring to. Get-Help is your friend.

This is a very basic function framework below. You could have dozens of commands running in that function. You technically don’t need a loop to run multiple paths through Get-ChildItem. You could do a Get-ChildItem $DirList. It’s easier than looping through it and combining the results. It really depends on what you plan to do with them. There are reasons you might want to process each folder in its own loop, and if you have that reason then you can use a loop to iterate through all of the directories in the array. In a classroom setting I could see a teacher expecting you to do it that way. I could also see a teacher saying that’s nice, but you could have just skipped the loop. Depends on the teacher.

function Get-Dirs {
    Param(
        [parameter(Mandatory=$true)]
        [Array] $DirList 
        )
    foreach ($Item in $DirList) {
        Get-ChildItem $Item
    }
}

Get-Dirs -DirList "C:\","C:\temp"

Ok, show us what you have tried so far and look at what Patrick suggested that should get you 90% there.

Ask if you have specific questions and provide the code you have tried.

I wish I had these kinds of homework assignments in school. It sounds way better than reading The Song of Roland.
