I just read the following command:

taskkill /f /im something.exe

I read that /f forces the task to close, but what does /im

    If you type the executable name and a /? switch at the command line, there is typically help information available. Doing so with taskkill /? provides the following, for instance:

    TASKKILL [/S system [/U username [/P [password]]]]
             { [/FI filter] [/PID processid | /IM imagename] } [/T] [/F]
    
    Description:
        This tool is used to terminate tasks by process id (PID) or image name.
    
    Parameter List:
        /S    system           Specifies the remote system to connect to.
    
        /U    [domain\]user    Specifies the user context under which the
                               command should execute.
    
        /P    [password]       Specifies the password for the given user
                               context. Prompts for input if omitted.
    
        /FI   filter           Applies a filter to select a set of tasks.
                               Allows "*" to be used. ex. imagename eq acme*
    
        /PID  processid        Specifies the PID of the process to be terminated.
                               Use TaskList to get the PID.
    
        /IM   imagename        Specifies the image name of the process
                               to be terminated. Wildcard '*' can be used
                               to specify all tasks or image names.
    
        /T                     Terminates the specified process and any
                               child processes which were started by it.
    
        /F                     Specifies to forcefully terminate the process(es).
    
        /?                     Displays this help message.

        WINDOWTITLE   eq, ne                    Window title
    
        NOTE
        ----
        1) Wildcard '*' for /IM switch is accepted only when a filter is applied.
        2) Termination of remote processes will always be done forcefully (/F).
        3) "WINDOWTITLE" and "STATUS" filters are not considered when a remote
           machine is specified.
    
    Examples:
        TASKKILL /IM notepad.exe
        TASKKILL /PID 1230 /PID 1241 /PID 1253 /T
        TASKKILL /F /IM cmd.exe /T 
        TASKKILL /F /FI "PID ge 1000" /FI "WINDOWTITLE ne untitle*"
        TASKKILL /F /FI "USERNAME eq NT AUTHORITY\SYSTEM" /IM notepad.exe
        TASKKILL /S system /U domain\username /FI "USERNAME ne NT*" /IM *
        TASKKILL /S system /U username /P password /FI "IMAGENAME eq note*"
    

    You can also find this information, as well as documentation for most of the other command-line utilities, in the Microsoft TechNet Command-Line Reference

    See the doc : it will close all running tasks using the executable file something.exe, more or less like linux' killall

    it allows you to kill a task based on the image name like taskkill /im iexplore.exe or taskkill /im notepad.exe

    It tells taskkill that the next parameter something.exe is an image name, a.k.a executable name

    C:\>taskkill /?
    
    TASKKILL [/S system [/U username [/P [password]]]]
             { [/FI filter] [/PID processid | /IM imagename] } [/T] [/F]
