.SYNOPSIS
 
    Logs keys pressed, time and the active window.
    
    PowerSploit Function: Get-Keystrokes

.PARAMETER LogPath

    Specifies the path where pressed key details will be logged. By default, keystrokes are logged to %TEMP%\key.log.

.PARAMETER CollectionInterval

    Specifies the interval in minutes to capture keystrokes. By default, keystrokes are captured indefinitely.

.PARAMETER PollingInterval

    Specifies the time in milliseconds to wait between calls to GetAsyncKeyState. Defaults to 40 milliseconds.

.EXAMPLE

    Get-Keystrokes -LogPath C:\key.log

.EXAMPLE

    Get-Keystrokes -CollectionInterval 20

.EXAMPLE

    Get-Keystrokes -PollingInterval 35

When I run this powershell script using the Get-Keystrokes -LogPath $env:temp\key.log command, I get this error.

Suggestion [3,General]: The command Get-Keystrokes was not found, but does exist in the current location. Windows PowerShell does not load commands from the current location by default. If you trust this command, instead type: ".\Get-Keystrokes". See "get-help about_Command_Precedence" for more details.

 

So then I run the Get-Keystrokes command and get this error

 So then I run .\Get-Keystrokes and the task goes through, except for the log is never created in the file path.

Can some people here please tell me what I'm doing wrong and let me know how to get this working?

Its a function.  You can't just run the script.  It will just build up the function and tear it down without running it.  To load it into your current session you can use get-content and get it raw and this invoke-expression the string and then you will have the get-keystroke command available or you can import it.

Import-Module .\Get-Keystrokes.ps1

After that you will be able to run the cmdlet.
