Getting started with the PowerShell If Statement

In this video, we do an introduction to using the PowerShell If statement and all of the nooks and crannies that go along with it. We look at If, ElseIf, and If and how you can get the most out of them.

I'm having trouble is there an e-mail I could use to contact you to ask you a few questions about my script ?

[Promos]

I'm having trouble with validating the value when it belongs to the status of a service (opposite to a Where-Object command where no matter what, it's always valid - Argh).
In the below example, I would like it to output the word 'talk' to screen when the IF is valid.
As I show in my example below, the variable value currently is "stopped", but IF does not see it so.
Where am I going wrong here?



PS C:\Scripts> $Service

Status Name DisplayName
----
Stopped WebClient WebClient



PS C:\Scripts> If($Service -eq "Stopped") {'talk'}

PS C:\Scripts> If($Service -eq 'Stopped') {'talk'}

PS C:\Scripts> If($Service -eq 1) {'talk'}

PS C:\Scripts> If($Service -eq 4) {'talk'}


PS C:\Scripts> If($Service -eq Stopped) {'talk'}
At line:1 char:16
+ If($Service -eq Stopped) {'talk'}

Please help me with these questions I'm having a hard time figuring them out:


1-Write the PowerShell code necessary to prompt the user to enter a number and store that value in a variable called $userPIN using a datatype of Int32.
2-Check if the userPIN entered is positive and if not print out an error message.
3-Check if the userPIN entered is at least 4 digits long and if not print out an error message.

I need PowerShell tutor can you help me, we can work something out.

[zubena]

i have made this $names=@('Audiosrv', 'BFE', 'BITS', 'Dhcp', 'Dnscache', 'DNS')
and then made this foreach($item in $names){get-service $item|select displayname, name, starttype, status}
i dont have service named DNS so i need to implement if statement that it could print that nonexisting service into a custom named .csv file and all others that are found in the list i need to put those to in seperate .csv file.
if you will reply me fast i would be grateful dude.

I appreciate professionals making content. That's why I paid for YouTube Premium. I do wish your introduction was not so verbose.

I think you should better consider that people who are following powershell lessons, are expected to have a minimum experiance of at least one easy programming language. Powershell is not the kind of topic for starters in programming language to learn how an if statement works. Powershell is not good nor suitable to reach their needs.

I believe that such basic issues in programming syntax and further details of the if statements, arrays, variables etc basics, are destructing the purpose of the most of the followers of your lessons, becasue they miss some powershell semantics while they are jumping time-bar during each lesson.

I guess a short example for each of the basic statements, emphasising the most common differences, in a single lesson, would be enough to explain for the followers who can really benefit these lessons.
