Shane, loving the videos on PowerShell! You're a good teacher! I was wondering if you could do a more advanced video on Arrays? I'm stuck, I've built on Array of Server Names from a XenApp command, then I have a ForEach statment running against that Array of Server Names, but I'd like to know how to Add additional information/psobjects into this existing array (the new information gathered from the ForEach statement), is this possible?

So here is what I would try first. In the steps where you create the object to put in the array add the properties you want to add later with dummy data. Then change the values later which should be straightforward. Try that?

As always, thank you for another great video. I follow a lot of your more recent PowerApps stuff, which has been brilliant. But I also need to get to grips with PowerShell for managing Teams permission policies and I was getting a bit lost in PowerShell for Teams. The ForEach and ForEach-Object and this Arrays video has been so helpful. I work at a school and we have gone heavily into Teams for remote learning. I need to make sure Teams policies are correctly set for students and staff and so if you ever feel inspired to make a video about Microsoft Teams Policy settings in PowerShell, that would be amazing.

I like the content and when some one provides the script example in the video description. Not a PowerShell expert and here to learn like you all. Sorry if i did not understand this correctly, If any one can clarify me this doubt. Instead of creating the array and exporting the data in CSV like the example in the video, The same can be achieved by using a 1 line command without an Array: Get-Process | Where-Object {$_.WorkingSet -GE "10000000"} | Select ProcessName, Workingset | Export-Csv -Path C:\Temp\mydata.csv So i am still not clear on the purpose of using an array from this example.

@gautamr3098

@@ShanesCows Thanks for the clarification. After some research I understood this using the below example: $Fruits=@("Apple", "Orange") When you type $Fruits this will return both Apple and Orange as the values in the array and I can further use numbers just to result Apple or Orange.

I have already watched the first two videos. Thanks!! Excellent way to teach PS. Now in this third video, in minute 5 you use as example (foreach $pp in $processes) and thereafter you list $proc (instead of $pp) and you were able to show the property "ws" for $proc. Should it be for $pp instead of $proc?. Or I missed something there?. Again, thanks. After seen a lot of PS videos, these are among the best.

Great work Shane

Cool video! Just a thought from one dev to another: when an array exceeds a certain amount of indices, the method of using the ‘+=‘ operator in an iteration will, if I understand PowerShell array objects correctly, quickly allocate much unnecessary memory due to the fact that PS arrays are immutable, thus this will create a new mirrored array object in memory just with this new index. An iteration of n times, will then result in n number of array objects created in the background with one increment each, where only the last one is complete. correct me if I’m wrong here - this is what I’ve learned about this data structure in PowerShell. To combat this and to have an object that behaves more like a List object in Python, when I iterate and append an array I usually instanciate an arraylist (collections.generic.list[string] or [int] depending on usecase) to have a mutable array which nicely adds with the .Add() method. I see your example as trivial between these two approaches but imagine a scenario with sublists of thousands of indices on a core server where ram == money. How goes your thoughts? / PS isn’t my ‘native tongue’ if you catch my drift.

I would love if you could upload some troubleshooting session.

The interesting scenarios are when we are struggeling so I think we should see you struggeling. Less staged and prepared

Great Shane, thanks. Big fan. Much prefer the ISE. I've been watching your videos in preparation for migrating my fileshares to sharepoint. Big sticking point was file dates. So I was going to buy your advanced script then I realised i had a problem. My problem is I have thousands of old pdf files. Before I migrate them to Sharepoint I want to run OCR on the them. I have Acrobat 9 Pro and it will perform OCR on the whole lot but it will not only change the modified date but the created date. It effectively creates new files (with same name if you so desire). So I've created the new files in a new folder. I have a csv with the file names and the original dates from the original folder and I can pull that into an array in Powershell (thanks to you) but I cannot work out how to use that to modify the CreationTime property of each of the new files in my new folder. Three days of Googling and trial and error keeps drawing blanks!. My csv columns are filename and filecreationtime. I thought it might be as simple as $MyArrayDates = @() $MyArrayDates = Import-Csv .\NewFileDates.csv ForEach-Object { (Get-Item $_.filename).CreationTime = (Get-date $_.filecreationTime) } No errors but it doesn't "DO" anything either! So obviously it aint that simple! I think the data in my arrray is good but wonder how I should format the filecreationtime in the csv, tried various with no luck. So for each file I want to find the matching name in the array and modify the filecreationtime with the corresponding date and time from the array. Or compare the two directories and copy the dates and times for each file from original folder to new folder. Any pointers gratefully accepted.

Thank you for this! I guess I still don't understand the differences between a list and an array though.

i have an interesting one, i am a beginner to PowerShell, i have a CSV file in which i have server information, service tag, serial number, is it virtual, IP address, MAC Address, etc. i am wondering if i have 2 lines the same but only 1 or 2 things are different, example IP and MAC address, is there a way to get this all on 1 line or variable, or array so i only have just that one line with all the information instead of multiple lines?

@ShanesCows

6 жыл бұрын

Long story short Yes. It would just require you reading in the data, doing some ifs and then writing data back out. Not something I can give you a quick answer to but with a lot of elbow grease I think you could do it.

I got really curious how come after importing the CSV you could still get values by the same property names until I looked back at 11:00 and saw they were exported like column names in the CSV file. This shouldn't be a shock to me since I did something similar in Java, but seeing this done in PowerShell so easily just blew my mind.
