How do I access the current account environment variables from powershell?

In PowerShell, you can access the environment variables of the current user's account using the $env: prefix. Here's how you can do it:

1. List All Environment Variables:
   To list all the environment variables for the current user, you can use the following command:

   powershellCopy code
   Get-ChildItem -Path Env:
   
   

   This will display a list of environment variables along with their values.

2. Access Specific Environment Variable:
   To access a specific environment variable, you can use the $env: prefix followed by the variable name. For example, to access the value of the "USERPROFILE" variable:

   powershellCopy code
   $env:USERPROFILE
   
   

   Replace "USERPROFILE" with the name of the environment variable you want to access.

3. Set Environment Variable:
   You can also set or modify environment variables using the same syntax. For example, to set a new value for the "MY_VARIABLE" variable:

   powershellCopy code
   $env:MY_VARIABLE = "NewValue"
   
   

Remember that the changes you make to environment variables within the PowerShell session will only be effective for the current session. If you want to persistently modify environment variables, you'll need to do so through the Windows System Properties dialog or the Registry Editor.

If you're working with system-wide environment variables (variables that affect all users), you might need to run PowerShell with administrative privileges. You can do this by right-clicking on the PowerShell icon and selecting "Run as administrator."
