PoshTip #4 – List all environment variables

PoshTip #4  – List all environment variables

Retrieving the list of current environment variables is very simply with PowerShell. The windows environment variables are mounted as PSDrive in PowerShell.

First method

Just run :

Get-ChildItem env:

You can use Get-Item to get the value of desired environment variable. Below, I get the current username :

Get-Item env:\USERNAME

or

(Get-Item env:\USERNAME).value

Second method

You can also list all the variables :

dir env:

or

ls env:
