If you are on PowerShell 2.0 use (Get-PSCallStack)[1]. Command . I've come across two methods of getting the calling function name: 1) (Get-PSCallStack | Select-Object FunctionName -Skip 1 -First 1). FunctionName and 2) (Get-Variable MyInvocation -Scope 1).
To use the Get-Content cmdlet to display the contents of a function, you enter Get-Content and supply the path to the function. All functions available to the current Windows PowerShell environment are available via the Function Windows PowerShell drive.
In a standard Windows PowerShell script or function, names of nested functions can be reused. Calls invoke the last function defined with the specific name before the call.
$MyInvocation Contains information about the current command, such as the name, parameters, parameter values, and information about how the command was started, called, or invoked, such as the name of the script that called the current command. $MyInvocation is populated only for scripts, function, and script blocks.
You can use $MyInvocation which contains some useful information about what is currently executed.
function foo { 'This function is called {0}.' -f $MyInvocation.MyCommand } If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
