PowerShell
This is my working notebook as I journey into PowerShell. I'll update it as I follow along with the Pluralsight course called Your First Day with Powershell from Jeff Hicks.
PowerShell background
PowerShell is a management engine built on .Net framework. The engine itself is hosted by an application to allow you to run PowerShell.
Consoles
There are two primary - the one that looks like cmd.exe, and the ISE (graphical console). The graphical console is only run on desktops.
It's probably easiest to create a PowerShell shortcut on your desktop, and in general, it's best to run it with admin/elevated privileges.
Check PowerShell version
$psversiontable
will give you version of PS running on your system.
Customize console
Right click the Window and click Properties. In Font tab you can change font size and style.
If you go under Layout and play with window sizes, make Screen Buffer Size and Window Size width value the same.
PowerShell ISE
Basically you can punch in commands in the top pane and have them run in the window below. You have options to split the screen horizontally, vertically or put everything in full screen mode.
In Tools > Options you can modify size/fonts, apply themes, etc.
From the regular "cmd" console, you can type ise to launch PowerShell ISE.
PowerShell help
Type help + name of command, like help get-service
. You might get an error/warning like:
So run update-help
to get the latest help files!
If running this command barfs up a bunch of red text, it's likely because you didn't run PowerShell in an admin/elevated session. So right-click the PowerShell shortcut and click Run as administrator.
Then, you might want to run get-help force
to force the get-help operations to run again.
And when that's all done, you can type clear to clear the console out!
Getting started with PowerShell
get-service
lists a crazy amount of detail on running services, which ones are started/stopped, their description, etc.
get-service bits
will give you info on just that service
help *service
will give you help syntax for service-related commands
get-service bits
will show whether or not bits is running
help *eventlog*
will list all matching commands, like
get-eventlog
by itself will basically say "What log are you talking about?"
get-eventlog system
will list out the system log entries
help get-eventlog -Parameter logname
will help you understand how to properly format the command
get-eventlog system -newest 5
will give you last 5 entries
Discovering commands
Use help get-command
for getting all the commands that are installed on the computer.
Running get-command
will list ALL commands that PS recognizes right from a command prompt.
get-command *process*
will list out all the commands with process in the name.
You can run commands that aren't PS commands! Example:
dir
netstat -n
net user
etc...
When you run commands in ISE, one gotcha is if you run netsh it'll bark at you that interactive console applications are not supported.
Update 8/21 - I've paused my Pluralsight subscription in lieu of a Codecademy subscription
