# Exercise - Run your first PowerShell commands

To make sure your system is set up to work in PowerShell, run a command to verify your installation.

1. Type $PSVersionTable and then press Enter. $PSVersionTable


Your output resembles the following text:

 Name                           Value
----                           -----
PSVersion                      7.0.3
PSEdition                      Core
GitCommitId                    7.0.3
OS                             Darwin 17.7.0 Darwin Kernel Version 17.7.0: Fri Jul  6 19:54:51 PDT 2018; root:xnu-4570.71.3…
Platform                       Unix
PSCompatibleVersions           {1.0, 2.0, 3.0, 4.0…}
PSRemotingProtocolVersion      2.3
SerializationVersion           1.1.0.1
WSManStackVersion              3.0


The output is formatted as a table. It provides information about not only your version of PowerShell but also your platform and edition.

For more information about your version of PowerShell, you can run a modified version of $PSVersionTable. 2. Type $PSVersionTable.PSVersion and then press Enter.

$PSVersionTable.PSVersion  Your output now resembles this text: Major Minor Patch PreReleaseLabel BuildLabel ----- ----- ----- --------------- ---------- 7 0 3  This output gives you more details about your version of PowerShell. Notice that running $PSVersionTable results in output that looks like a table but is actually an object. So you can use a dot (.) to access a specific property like PSVersion.
