Unlike most other tools, PowerShell does not offer us a -version flag to tell us its version number. There is a -Version flag (with a capital V), but that we need to use a specific version of PowerShell. What can we do to find out what version we run?
We can open a PowerShell terminal and type $PSVersionTable:
|
1 2 3 4 5 6 7 8 9 10 11 12 |
$PSVersionTable Name Value ---- ----- PSVersion 5.1.19041.3930 PSEdition Desktop PSCompatibleVersions {1.0, 2.0, 3.0, 4.0...} BuildVersion 10.0.19041.3930 CLRVersion 4.0.30319.42000 WSManStackVersion 3.0 PSRemotingProtocolVersion 2.3 SerializationVersion 1.1.0.1 |
This shows us detailed table full of version information about all aspects of PowerShell. In my case, I have version 5.1 running on my machine.
