It seems nomatter what I do it won't let me run scripts. It keeps saying that i have unauthorized access despite setting the policy in both PS and ISE in either order, with administrative privileges. I'm on W11, PS version 5 latest build.
Hey Nolan! Try running Set-ExecutionPolicy unrestricted in PowerShell run as Administrator. I have seen that RemoteSigned sometimes still makes it limited. I'll add that note as an annotation to the video. Thanks for the catch!
@@PowerShellEngineer Thank you very much, that worked 👍👍
Sudo
@@PowerShellEngineer also, you should be able to open Power Shell in Admin mode.
@@PowerShellEngineer Does this have to be done in safe mode, or in startup terminal? I use linux and mac mainly, and rarely run a windows hypervisor or emulator, so I thought I’d ask.
I found the best way to fix all errors in PowerShell. Change the font color of errors to match your background color. If you can't see the errors, they don't exist.
😂
Lmao! 😂
Not only get a get a nice refresh in PowerShell, but I also got to learn about the Pokémon regions.
Very nice course! Stuff nicely explained in a straightforward way, this is what I've been looking for.
But maaan... Your voice is so quiet throughout the whole video! That outro jingle with the volume up spooked me out 😅
Anyway, thanks for the knowledge, I wish you all the best!
Cheers!
Thank you, Karol! Yes, I have to get the volume and aspect ratio right on my next videos 😅 I've got more videos styled like this coming. I'm finishing editing on my PowerShell book I've been working on since November right now.
Thank you!
DO YOU KNOW DOS COMMAND TO MAKE SHORTCUT FILES ?
please add chapters to the video so it'll be easy to navigate
1:22:42 This is where the SHELL part starts
the video is great, but the audio has issues, intro was bit too loud
Well organized, well spoken, easy to understand tutorial. For some reasons, volume is low (I experience this volume issue on some other online videos - but not all videos).
using -eq and -ge etc is so dumb. We already have symbols for these, why make things different in a worse way? Really, at this stage, I just want C# scripting.
Hey James, Great video. at the 50 minute mark you are doing some if elseif stuff with Pokemon regions. I tried it and found that any number =100 causes proper output. I believe your variables are strings, would this cause this type of error?
Great video, any other resources you recommend to keep learning PS.
Update: this video helped my buddy to ditch the GUI and to be comfortable doing it! Yay!!!
This is fantastic!! Thanks! I’m recommending this to a friend who uses windows exclusively, who hasn’t ditched the GUI yet. This really is a great tutorial. Appreciate you.
I took powershell in college.
++GOOD! Watched a ton of videos on the topic the last 2 days - this one is by far the best: well structured, understandable examples, fun to key along in my own system.Keep up the good work!
😊
Great examples.. Star Wars and Pokemon :) i like that. easier to learn that stuff
Glad you liked it!
this is not a PowerShell course it is a programming course, you joking??
Sorry for the newbie question but at around 30 mins you type = @(‘ObiWan…’) what is the @ symbol for?
Hey, no worries at all! That is called the array subexpression operator - you don't technically need it - you could do $jedi = "Obi-Wan","Anakin" and it would work the same 🙂
@@PowerShellEngineer understood now so thanks a lot 👍
Very cool learning video. Specially when I found out you are a fan of LOTR :))
I had my doubts about you and 2 hrs but I have to admit that this gets down to the nitty gritty. Thanks for taking the time.
Thank you, I'm glad it was helpful! If you're interested, I have a video just on automation in under one hour that I think is kind of a next step from this video.
@@PowerShellEngineer I will definitely check it out. I subscribe now.
I got a call On powershell scripting Language (automation)based project..did it usefull to take the project.and is it use full in future..?
Give some suggestions guys please
I like those fun examples! Thank you!
You are welcome!
For execution policy, I got this error:
PS C:\Users\hssna\music> Get-ExecutionPolicy
Restricted
PS C:\Users\hssna\music>
So, you want to run Set-ExecutionPolicy Unrestricted
That will allow you to run scripts on the system.
great stuff thanks. was in bash world for so long and as soon as wsl2 and powershell v6 became a thing i was like "ok windows is now my machine - and i can build stuff easily cross platform too"
1:04:00 you wrote "Foreach ($peep in $HaloPeeps)", why did you use "$peep" as the value? It's part of the array $HaloPeeps; how does Powershell know to use each value in $HaloPeeps when calling $peeps for "Write-Host $peep 'has arrived' "? Is $peep a built in mechanism in PowerShell?
From Microsoft Learn, it gives this example: "foreach ($ in $){}
The part of the foreach statement inside parenthesis represents a variable and a collection to iterate. PowerShell creates the variable $ automatically when the foreach loop runs. At the start of each iteration, foreach sets the item variable to the next value in the collection. The {} block contains the commands to execute for each iteration."
It's just implicit to the way that a foreach loop works in PowerShell. There always has to be a placeholder item variable to represent the current value as it iterates through the collection.
I appreciate at the references used for programming. I didn't realize we were up to 908 pokemon these days. But I'm partial to the Johto region.
I made this mistake back in 2015 and I promise my self not to do it again. Just learn Bash
Thanks mate, good vid. Newbie here and learnt a lot, much appreciated.
great video man ,great content.. i am begginer with basic python knowledge yet i was able to understand everything thanks a lot
No problem! I'm glad you enjoyed it.
Complete NOOB here, I used Set-ExecutionPolicy unrestricted, as admin but I still get the red cd : Cannot find path 'C:\Scripts' because it does not exist.
At line:1 char:1
+ cd C:\Scripts.
Windows 10 Pro v 1909
You would need to make the C:\Scripts directory - you could do that with
cd C:\
New-Item -ItemType Directory -Name "Scripts"
or just
mkdir C:\Scripts
Tried #My First Comment. It still showed the comment. Wouldn't go away
Can you share your code?
how do you make a key press thing like:
if plus pressed, press h
Nice vid, touched every major topic.
Do you happen to know a good static analyzer for PowerShell?
Yes, the PSScriptAnalyzer from Microsoft. Though the GitHub plugin for VSCode works really well - I used it to audit my disk cleaner script.
e si che, con tutti quelli che vi hanno dato in campionato, avete avuto tempo per prepararvi..
Thank you james👍
Do you recommend books for learning PowerShell and automating with PowerShell
Hey SysAdmin, I just recently finished my book, PowerShell for Systems Engineers - it's available on Kindle for now - I'm proofing the print version. I'm almost done with a companion course. www.amazon.com/dp/B0C12DPZ2C
@@PowerShellEngineer
I am happy that you released book about PowerShell, is it tutorial or strategy book
in addition, Do you provide workshop or course for specific subjects, for instance, I want to learn how to use ASDI in PowerShell for Active Directory and GPO.
Thank you, that was very easy to follow & made a lot of Sense!
Thanks!
Hi, great vid so far in 30 minutes or so.
I use power shell in general for deploying applications via sccm. Pretty basic stuff probably from your perspective. Start-process etc with silent switches and so on for msi and exes etc.
Are there any links or urls you could advise that would help with this particular area of power shell and deploying apps or making changes to a systems file system for example (usually deploy the ps script via sccm with a admin service account to the remote device)
Seen some folk get really into a massive long script with other app deployment, I have no idea how they manage to retain the information to write from scratch to be honest. Personally I grab other people’s code online, test and then make it cater for the app in question needs (if it needs to be installed when the device has batter greater than 10 percent for example)
Would it be possible to message you a couple of questions with some scripts I have for you opinion on them?
Thanks 🙏
Also, what best helped you retain the way you can just write the code like that, right off bat?
Yes, the @pdq channel has some good resources for app deployment. I honestly am testing code the same way for the things I do as well. I often setup a test server just to make sure I don't inadvertently do something bad to my own PC or my server. Feel free to message me on TH-cam or Twitter!
@@HBOMB-nl9pw I've been writing a book on PowerShell which will be out soon and I when I made this it was fresh off of two presentations in PowerShell, so I had done (and continue to do) a lot of scripting. Even still, I write something in PowerShell almost every day, even if it's just a little, so it keeps it fresh. For the video I did have an outline so I could keep track of what to move on to next to compress it down :) I would come up with a project to keep the challenges going and stay engaged.
@@PowerShellEngineer been using and testing chatgpt to write test scripts and it’s really good so far, it wrote them similar to how I have which is good 🙂

Hello Sir!..
...My English is not that good (lvl B1 still learning :P) ..anyways, that's not the case though lOl, I'll try to explain as much as I can :P...
I'm new to "Powershell" (still learning the basics..) and briefly, STEP 1 I'm trying to read two different .txt files...the files are simply ranked words (from A to Z) but the words are not the same in each file though, say for example : file 1 path = "c/words/SectionA.txt" , file 2 path = "c/words/SectionB.txt"..STEP 2 matching the words in file 1 (line by line) with a string (text blah blah) and return the result to a variable (say $Result/Match= $Line , $Line_Number)..STEP 3 in file 2 reading only lines that match $Line_Number in "$Result/Match" ($Result/Match= $Line_Number)
STEP 1 & STEP 2 were easy but stuck on STEP 3 (reading the specific lines which match the result $Line_Number)
//$Index = "E" #reading files based on letters ex : A.txt, B.txt.....
//$FilePath = "C:\Read\{0}*.txt" -f $Index
//irrelevant//
$FilePath1 = "c/words/SectionA.txt"
$FilePath2 = "c/words/SectionB.txt"
$regex = read-host "Write something"
if([string]::IsNullOrEmpty($regex) -eq $true){
Write-Warning "Null Or Not Found"
exit
}
$l = 1
switch -regex -file $FilePath1 {
$regex {
"$l , $_"
$l++
STEP 3 GOES HERE ......
}
}
...anyone can help me with this and I'll be very grateful..thanks in advance + excuse my poor language :P..Peace!.
Maybe something like this?
$FilePath1 = "C:\words\SectionA.txt"
$File1Content = Get-Content $FilePath1
$regex = Read-Host "Enter the string to match"
if ([string]::IsNullOrEmpty($regex)) {
Write-Warning "Null or empty input"
exit
}
$Result = @()
$Line_Number = 1
foreach ($line in $File1Content) {
if ($line -match $regex) {
$Result += "$Line_Number, $line"
}
$Line_Number++
}
$FilePath2 = "C:\words\SectionB.txt"
$File2Content = Get-Content $FilePath2
$FilteredLines = @()
foreach ($entry in $Result) {
$LineNumber = $entry.Split(',')[0] -as [int]
if ($LineNumber -gt 0 -and $LineNumber -le $File2Content.Count) {
$FilteredLines += $File2Content[$LineNumber - 1]
}
}
Write-Host $FilteredLines
"Edited" ..that's not what I'm looking for but it helps Thanks anyways .. have a good day :). @@PowerShellEngineer
Actually that was easier than I thought...
all that I need to do is finding the matched words lines (*Only* $Lines_numbers without $Lines) ..and then later I can use them as "$Index" to get the specific lines from file2..for example :
#########
$FilePath1 = "C:\words\SectionA.txt"
$FilePath2 = "C:\words\SectionB.txt"
$File1Content = Get-Content $FilePath1
$String = Read-Host "Type something"
if ([string]::IsNullOrEmpty($String)) {
Write-Warning "Null or empty input"
exit
}
$String += "*"
$FilteredLines = @()
$Line_Number = 0
foreach($Line in $File1Content){
if($Line -like $String){
$FilteredLines += "$Line_Number"
}
$Line_Number++
}
if([string]::IsNullOrEmpty($FilteredLines)){
Write-Warning -Message "Not Found"
exit
}
$Result1 = (Get-Content -Path $FilePath1 | Select-Object -Index ($FilteredLines))
$Result2 = (Get-Content -Path $FilePath2 | Select-Object -Index ($FilteredLines))
#Display Contents
$Result1 + "" + $Result2

that's it. (that was much fun ☺)..

I'm on linux & stumble to this ...Why not ~
Hi, When I type net session in Powershell, it shows me an SMB connections. Is there a way I can show SSH connection from PowerShell?
Get-NetTCPConnection will show you all of the TCP connections. You could filter that down by piping it to a Where-Object that looks for port 22 connections: Get-NetTCPConnection | Where-Object { $_.OwningProcess -ne 0 -and $_.RemotePort -eq 22 } | Select-Object LocalAddress, RemoteAddress, RemotePort

@@PowerShellEngineerbro Execution Policy enable put us in any dangerous things?
The best intro PS. Thank you 🙏
i hate working with windows power shell since it has the c:/User/{name}/etc/etc/ which feels slower to write then ~\etc\etc the c: is really a turn off idk why
So, a lot of my options are blurred out. What does that mean? i cant run anything, even though I am admin, and set policy to remotesigned?
Set the policy to unrestricted and you should be good :)
@@PowerShellEngineer ahh okay, thank you sensei.
thank you. ❤❤
ughh, I feel like all of this i can figure out, and i totally get it while watching. It doesnt seem difficult to me in the slightest. The issue for me is, if i had to figure it out on the spot... I am looking for a entry level sys admin job. Can I say that I know powershell? I couldn't recreate this video off the top of my head. BUT if i was asked to do something, I could 100% figure it out. And if i was doing it on a daily basis, I would master it extremely quickly... So can i say that I know powershell?
is this imposter syndrome? Do i just not know it?
That was a very helpful video, keep it up! :)
Great watch sir, What book would you recommend for o365/Azure consultant to learn powershell? Thanks
Rookie question (doesn't come super easy to me!). How do you decide when to write the script in the script window and when to do it in the console window?
Hey! Great question. I write code in the PowerShell ISE script window when I want to save the script to run it again later or if I want to make a scheduled task to run the script automatically. In the console, I would run code if I'm just wanting to check something, like Get-Volume (for example) to check disk space or Test-NetConnection to see if a website or server is up.
Try doing something like this using VS CODE PowerShell extension.
Thank you-I was able to learn PS basics- I like your teaching style..too good🤘
Glad you liked the video and glad I could help!
Thank you. This video was so helpful. I'm just starting my journey learning PowerShell and this was so helpful. You gave me some confidence in learning it now.
WOW just wow! I got chat gpt to make a script that outputs a template for me based on my answers and I've been struggling to edit it as I don't know much, I'm only 18 minutes into this video and i was able to understand my script and make the correct edits!
Thank you for the video. Very helpful. May the force be with you.
Thanks for the video.
Hey James, I am a graduate who is trying to get into system administration and I am learning both linux and windows server. I have basic knowledge in programming and bash shell scripting. I was confused if I should learn python for scripting as it is cross platform, or just move on with powershell and bash shell. Can I get your opinion?
I don't think you would be worse off for learning Python. I'd actually recommend learning all three. That said, for systems administration, PowerShell and Bash would be more useful. Additionally, PowerShell Core 7 is available on Windows, Mac, and Linux!
@@PowerShellEngineer learning all three? I wish I have the time.
If I have to pick one first to start, what we you recommend? Thanks.

Great video and great examples 😊 🎉
Brother this is very informative and helpful! Thanks heaps!
hey is it possible to embed tmux status line into powershell?
This is what one could look like; I'm not sure how to keep it present on the shell though:
while ($true) {
# Get current time
$time = Get-Date -Format "HH:mm:ss"
# Get CPU usage
$cpuUsage = (Get-WmiObject Win32_Processor).LoadPercentage
# Get memory usage
$mem = Get-WmiObject win32_operatingsystem
$memFree = "{0:N1}" -f ($mem.FreePhysicalMemory/1MB)
$memTotal = "{0:N1}" -f ($mem.TotalVisibleMemorySize/1MB)
$memUsage = "{0:N1}" -f (($memTotal - $memFree) / $memTotal * 100)
# Build the status bar string
$status = "Time: $time | CPU: $cpuUsage% | Memory: $memUsage% used ($memFree MB free of $memTotal MB total)"
# Clear the current line and write the status
Write-Host -NoNewline "`r$status"
# Sleep for a second before updating
Start-Sleep -Seconds 1
}
@@PowerShellEngineer really appreciate it thank you but seems like icons are missing 😁😁
thanks for the lesson
Thank you so much
As a new PowerShell user this was super helpful and you presented it in a fun easy to understand way. Thanks
This helped me so much
I remember when Microsoft Windows wanted to get rid of the DOS command line. Most people these days probably don't even know what that is anymore. This was in the 90s. They said "With Windows, you don't need to type commands anymore." Ok, thanks. That's great.
Several years later..."Here's Powershell. We want you to learn a whole new set of 50,000 commands again." Good lord. What is the matter with people?
And why do these commands have to be so deliberately different than Linux? Feels like a personal agenda against using already established industry wide accepted commands to do even simple stuff
This was so helpful! Thank you!
thanks

Probably one of the better tutorials! Mike from MI
Can you please help me create group manage service account, a basic one and start any service using that gmsa account
This is untested, but something like this should work: New-ADServiceAccount -Name gmsa -DNSHostName -PrincipalsAllowedToRetrieveManagedPassword
and then you can collect the password and restart the service with this:
$secpasswd = ConvertTo-SecureString "" -AsPlainText -Force
$mycreds = New-Object System.Management.Automation.PSCredential("DOMAIN\gmsa", $secpasswd)
Start-Service -Name Spooler -Credential $mycreds
Truly amazing tool !
