PowerShell Functions

Learn how to work with PowerShell Functions. In this episode of Learn PowerShell I dive into what makes up a PowerShell Function. Discover the difference between an advanced and standard PowerShell function. I also tackle the question of why you might write a PowerShell Function vs PowerShell Script. Go beyond theory - this episode uses real life fully functional PowerShell Functions to explore how functions are made and how they operate.

I wish I could like this many more times, I have spent weeks reading and trying to understand functions. This 30ish minute video has shot my confidence and understanding of functions through the roof and I look forward to building my own functions now. THANK YOU for making this video, it's been a tremendous help, so much more to discover on my own but I have learn enough here to feel confident moving forward.

Edit:
One month later and I have grown to making my own modules and even manifests. Been sharing the tools I've made and this all around has been so useful

Went on and donated since this is one of the best courses on coding. The info is available everywhere but the structure and the practical examples makes the difference.

No way! I started learning ps a week ago and now you continue the series :D
Thank you very much for your awesome work!

As a DevOps engineer who uses PS alot, I learnt a few things and my knowledge was solidified further after watching this. Nice video! Subscribed.

[boazrosen]

Amazing tutorial and the best I've see about PowerShell functions. Thank you so much!

[Tegle]

Like Moss from the IT-Crowd would say, "This is INSANELY brilliant!"

[csmith]

Super helpful and just what I needed; thank you for the completeness of this video!

[MeOnTheStreets]

Learning a lot with these series! thanks!

[prasadsardeshmukh]

Amazing explanation. Way better than Microsoft's documentation :-D

[yavor]

Great presentation. Thank you for your efforts!

[wasimbagwan]

Thank you very much!! Really Helpful!!

[abhishekkumar-zsle]

Thanks for bringing powershell functions. If possible please keep on bringing new videos. It's very heplful

[kalyanben]

right after the function ends.. why do you comment function name? At @25:30, right after function definition ended, you commented on its name.. is there any advantage or just for clarity?

[Cyrixau]

How many more videos in the series do you think are left? Also do your blog posts contain all the same info from the youtube vids?

[kolesplace]

You have some great instructions. Do you have instruction on the higher level aspects of PowerShell. I have written functions but did not know until I watched this video that I need to type (. ./filename) for my file to be recognized. What does that do?

[CaptainQwerty]

I must know how you make your cursor blink in that style! Very pleasing compared to a flashing cursor

[mikuj]

Finally, I can start to make my vim-plug manager lol

[zeroexct]

Great tutorial but the difficulty spike of this from pws logic vid is massive.
