Learning Windows PowerShell is like learning to use a universal multi-tool. In this post, I cover PowerShell scripting basics so you can more easily perform virtually any administration task related to your Windows IT environment. PowerShell offers both a command-line option and an integrated scripting environment ISE: To launch the PowerShell command line, type powershell.
So now that we know where we can find the information we looking for, open up the ISE and type the following.
I had to split my code over two lines so that it all fit into the screenshot, but feel free to type it on a single line. If you do choose to split it over two lines, please make sure that the pipe character is the last character on line 1.
WMI times can be a little cryptic. By that we mean if you look at the LastBootUpTime property, it says at You will need to change the Select-Object part of the code to look like this: Your code should now look like this.
Running the code now will yield a much more readable last boot time. Now that we are happy with the basic functionality of our script, we need to save it. Our script is working as expected, however there is still one problem with our script.
We hardcoded the name of the computer we want to get the last boot time for. Instead of hardcoding values, we should rather provide a parameter so that whoever is using the script can choose which computer they run the script against.
To do that, go to the top of your script and do the following. Your script should now look like this: Save your script, then head back to the bottom half of the ISE and view the help for your script.
Unfortunately, there are still a few things wrong. To make the ComputerName parameter mandatory, change the contents of the param block to the following. That means we just add an extra long comment to the top of out script.Using the PowerShell ISE is the preferred way to work with the scripting language, because it provides syntax highlighting, auto-filling of commands and other automation features that simplify script development and testing.
