Displays the current call stack.


The following abbreviations are aliases for this cmdlet: 

  • gcs


Get-PSCallStack [ <CommonParameters>]

Detailed Description

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: -Debug, -ErrorAction, -ErrorVariable, -InformationAction, -InformationVariable, -OutVariable, -OutBuffer, -PipelineVariable, -Verbose, -WarningAction, and -WarningVariable. For more information, see    about_CommonParameters.


The input type is the type of the objects that you can pipe to the cmdlet.

  • None

    You cannot pipe objects to this cmdlet.


The output type is the type of the objects that the cmdlet emits.

  • System.Management.Automation.CallStackFrame

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


-------------------------- EXAMPLE 1 --------------------------



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.

function my-alias {
$p = $args[0]
get-alias | where {$_.definition -like "*$p"} | ft definition, name -auto
PS C:\ps-test> set-psbreakpoint -command my-alias
