Get-PSCallStack
Displays the current call stack.
Syntax
Get-PSCallStack [] Description
The Get-PSCallStack cmdlet displays the current call stack.
Although it is designed to be used with the Windows PowerShelldebugger, 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.
Examples
Example 1: Get the call stack for a function
PS C:\> function my-Alias {
$p = $args[0]
Get-Alias | where {$_.definition -like "*$p"} | format-table definition, name -auto
}
PS C:\ps-test> Set-PSBreakpoint -Command My-Alias
Command : my-alias
Action :
Enabled : True
HitCount : 0
Id : 0
Script : prompt PS C:\> my-alias Get-Content
Entering debug mode. Use h or ? for help.
Hit Command breakpoint on 'prompt:my-alias'
my-alias get-content
[DBG]: PS C:\ps-test> s
$p = $args[0]
DEBUG: Stepped to ': $p = $args[0] '

Get-Content typeThis 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, a33 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.
Inputs
