Learn PowerShell: Episode 8, Operators + If Statements + Scripting Tips

Welcome to the eighth episode in the long-running PowerShell video series. This is nearing the very last episode now, and the bonus episode where we're going to make an entire graphical app.

In this video, we focus on two main things: If Statements and operators!

Operators are not a new concept to us, they've been there the entire time we've been using PowerShell, we just haven't noticed them much yet. In this episode, we're going to look at what operators are, and recap some of the things we already know about them. Once we've recapped that, we're then going to look at new concepts with operators, clarifying their behaviour in certain situations, as well as looking at entirely new operators we haven't covered, or operators we very briefly touched on previously, but haven't looked at in-depth much since then.

We're also going to take a look at "operator precedence", which is a concept you're also already very familiar with, from basic Mathematics, but, again, may not have really noticed before. This is a concept we'll also look at, and we'll see the implications of this and use it to help clarify some ways PowerShell makes using operators easier for us.

Once we've covered the concept of "operator precedence", we're going to move into some new scripting concepts, such as writing comments or indentation. These are things we apply to scripts to make them more readable and maintainable.

And then, we'll move onto "if statements", a very important feature that gives us huge flexibility in our scripts. Watch to find out more!

Thanks a lot for this video's I really like the way you explain things !

[stianiversen]

Your tutorials are really great, I appreciate how you "deconstruct" everything and explain each part before "assembling" it again. You make a lot more sense than any of the other tutors I have found on YT :-)

[karyazin]

Awesome tutorials! Thank you, Man! Waiting for new episodes)

This is still the best PowerShell breakdown on YT to date. I blasted you on PowerShell reddit.

This info plus learn PowerShell in a months lunches edition 4 will fast track you right away.

I have watched a couple series on powershell that say for beginners but seem hard to follow. Your series has been great and I look forward to the next episode.

I recently completed your third PS video. I have worked in IT for 32 years and have been able to skip around learning PS until now, but while some say 'better late than never' meh, not so much working in IT. There are so many people teaching PS on YouTube but your videos are clicking with me. I can't identify why but they are. By any chance are you available to hire for one on one lessons for training on specific things I am trying to do in PowerShell?

I am intrigued by this tutorial. I'm motivated to figure out how to repeat the question if the answer is neither yes nor no... Any hints?

Video shows "Identation" instead of "Indentation"...
