We can get a single variable.
PS> $env:path
Or get all of them at once.
PS> gci env:
However, since each environment variable result is truncated to a single line, you will not be able to see all of certain ones – like Path. Use below to wrap all the values to multiple lines.
PS> gci env: | format-table -wrap PS> gci env: | ft -wrap # Using alias
Set Environment Variables
To set an environment variable for the current session.
PS> $env:NewVar = "This is a new variable"
Once the PowerShell command window is closed, the variable will be lost. Also, the variable is not available to other command windows.
