NAME

Get-PSCallStack

SYNOPSIS

SYNTAX

Get-PSCallStack []

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`.

PARAMETERS

This cmdlet supports the common parameters: Verbose, Debug, ErrorAction, ErrorVariable, WarningAction, WarningVariable, OutBuffer, PipelineVariable, and OutVariable. For more information, see about_CommonParameters (https:/go.microsoft.com/fwlink/?LinkID=113216).

INPUTS

None You cannot pipe objects to this cmdlet.

OUTPUTS

System.Management.Automation.CallStackFrame

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

NOTES

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] '

[DBG]: PS C:\ps-test> s

get-alias | Where {$_.Definition -like "*$p*"} | format-table Definition,

[DBG]: PS C:\ps-test>get-pscallstack

Get-Content type

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.
