----------- 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.
