Displays the current call stack. (Get-PSCallStack)



Displays the current call stack.

Get-PSCallStack [<CommonParameters>]

The Get-PSCallStack cmdlet displays the current call stack.

Although it is designed to be used with the Windows PowerShell debugger, you can use this cmdlet to display the call stack in a script or function outside of the debugger.

To run a Get-PSCallStack command while in the debugger, type "k" or "get-pscallstack".

This cmdlet supports the common parameters: Verbose, Debug,
ErrorAction, ErrorVariable, WarningAction, WarningVariable,
OutBuffer and OutVariable. For more information, type,
"get-help about_commonparameters".

You cannot pipe objects to this cmdlet.

Get-PSCallStack returns an object that represents the items in the call stack.

$p = $args[0]

# Description
This command uses the Get-PSCallStack cmdlet to display the call stack for My-Alias, a simple function that gets the aliases for a cmdlet name.

The first command enters the function at the Windows PowerShell prompt. The second command uses the Set-PSBreakpoint cmdlet to set a breakpoint on the My-Alias function. The third command uses the My-Alias function to get all of the aliases in the current session for the Get-Content cmdlet.

The debugger breaks in at the function call. Two consecutive step-into (s) commands begin executing the function line by line. Then, a Get-PSCallStack command is used to retrieve the call stack.

The final command is a Step-Out command (o) that exits the debugger and continues executing the script to completion.
