"Friends, Romans, countrymen, lend me your ears!" Ok, this isn't a Shakespeare blog but PowerShell continues to be sung from the mountain tops and it's only getting louder. So much so, that I wish I had a nickel for every time I heard the phrase "you can do that easy in PowerShell." Well, my dad used to say, "Nuthin's easy." However, with a bit of basic PowerShell under your belt, many, many things get easier (note, I didn't say 'easy' J ). By 'things' I mean A LOT of things. AD? Check. Hyper-V? Affirmative. Azure? Ci, senior. Got hotfixes? Indeed. DNS? Uh-huh. DHCP? Yep. You get the point.
So, let's cover some of the basics of PowerShell and get you some One-liners to get you rolling:
Now, I present a fistful of handy PowerShell One-Liners from myself and a few PFE Brothers in Arms (Tom Moser of Ask PFE Plat fame and one Mr. Ashley McGlone, whose own blog is a PowerShell buffet: http://blogs.technet.com/b/ashleymcglone/
Take note in the code how we snuck in a variety of output switches … this is yet another helpful element of PowerShell.
Let's roll … The server rebooted recently - who did it and when exactly?
Here's a timely post from Ed Wilson about Get-WinEvent: http://blogs.technet.com/b/heyscriptingguy/archive/2014/06/04/data-mine-the-windows-event-log-by-usi... Is there an easy way to see if KB2862152 is installed?
If the patch is installed, you'll get a nice formatted output of where/what/who/when:
Source Description HotFixID InstalledBy InstalledOn
------ ----------- -------- ----------- -----------
DC01 Security Update KB2862152 DC01User-01 4/22/2014 12:00:00 AM If the patch isn't installed, you'll get an error stating so:
Get-Hotfix : Cannot find the requested hotfix on the 'WS2012r2-dc01' computer. Verify the input and run the command again.
I need to backup all of the GPOs in the domain every day
What are the IP settings on my system(s)?
What are the BIOS versions on my systems?
A few more …
At this point, you should have noticed some patterns to those One-liners (and to the PowerShell syntax in general). That is one of the key elements that makes PowerShell easier. If you get a handle on how to get event log info out to a CSV file, it isn't much different to get hotfixes, or AD user attributes. If you have yet to get going with PowerShell, now is as good of a time as any – take 15 minutes each day over the next week (first thing in the morning or after lunch are often good times) and work through these examples. If these one-liners didn't pique your interest, make a list of 5 things you think would be easier with automation and figure out how to do them in PowerShell.
