PowerShell Master Class - PowerShell Scripting

[@iamdedlok]

Thanks John! Great content. I grew few brain cells in the last 30 min. Watching your content daily for 30min in the morning is the new 'discipline' I have been building :D On to the next 'Advanced Scripting' vid!

I went through the Microsoft powershell training tutorial. You gave me a lot of good information.

[@NTFAQGuy]

[@bjorndennenbroek1284]

Thank you, these video's are a tremendous help.

[@patrickwilliams7210]

I noticed on your section at 8:58 you include the execution operator '&' it doesn't appear that you need that for the script to work.

[@zt.5677]

Dear John. Funny thing is: I have just seen your motivational on discipline, and I thought: is it discipline that after my SQL examination, I return to John's PowerShell Class to continue and finish them?

[@NTFAQGuy]

:-)

[@alishavez]

Good stuff John.

[@NTFAQGuy]

Thanks :-)

[@TheMarcosmf]

Where could I find the concept of Parameters and Strings? I watched PowerShell Fundamentals and I couldn't find it there. I supposed was here.

[@badsector82]

What's the difference between "Write-Output" and "return" in a function?

[@Codyyyyyyyyyy]

Great video! Thanks

[@badsector82]

What if I have script to do a task for a million users, for example and I want to have a progress shown on the screen. Should I use "Write-Output" as it can possibly mess with the pipeline, and I have had such cases, or I am allowed to use "Write-Host"?

[@NTFAQGuy]

check the firewall is open etc. it can't get to the machine.

[@pallabkolkata]

@@NTFAQGuy Yes it is my local laptop only.

If you code doesn't run in powershell, and shows "cannot be loaded because running scripts is disabled on this system", copy and paste this: Set-ExecutionPolicy RemoteSigned -Scope CurrentUser

[@PaulBunkey]

About "Just don't use it" - I don't support boycotting a language command. You just need to understand pros and cons and use an appropriate command. (As I see it) Write-Host is only useful if you want to make output more readable for user, staring at the console. If you always write to log and never need to inform a user about the process or give beautifully readable result, with important parts jumping to the eye, so yeah, never use Write-Host.

[@pgrinius]

Hi John, what a great video! Superb quality and straight to the point. I noticed, that Write-out at 29:38 outputs Version before Procs, which is the opposite of how you set up the $paramout hashtable. What’s the reason for that?

[@NTFAQGuy]

Thanks. Hash table is a collection of values, how its output does not have to match. I could control the output format if I wanted to but didn't in this example.

[@yusril-ihsanul-alim]
