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.
