echo/access environmental variables from powershell

In PowerShell, you can echo/access environmental variables using the $env automatic variable or the Get-ChildItem cmdlet. Here are a few examples:

1. Using $env variable:

   • To echo the value of a specific environmental variable, use the following syntax:

     powershellCopy code
     echo $env:VariableName
     
     

     Replace VariableName with the name of the environmental variable you want to access. For example:

     powershellCopy code
     echo $env:Path
     
     

   • To list all environmental variables and their values, you can iterate through the $env variable like an associative array:

     powershellCopy code
     foreach ($key in $env.Keys) {
     
         echo "$key = $($env:$key)"
     
     }
     
     

2. Using Get-ChildItem:

   • To list all environmental variables and their values, you can use the Get-ChildItem cmdlet with the Env: drive:

     powershellCopy code
     Get-ChildItem Env:
     
     

   • To access the value of a specific environmental variable using Get-ChildItem, use the following syntax:

     powershellCopy code
     (Get-ChildItem Env:VariableName).Value
     
     

     Replace VariableName with the name of the environmental variable you want to access. For example:

     powershellCopy code
     (Get-ChildItem Env:Path).Value
     
     

These methods allow you to echo/access the values of environmental variables in PowerShell. Choose the method that suits your needs and preferred syntax.
