killall is a command line utility available on Unix-like systems. There are two very different implementations. The implementation supplied with genuine UNIX System V (including Solaris) and Linux sysvinit tools kills all processes that the user is able to kill, potentially shutting down the system if run by root.
The taskkill command on Microsoft Windows. In Microsoft's command-line interpreter Windows PowerShell, kill is a predefined command alias for the Stop-Process cmdlet. Microsoft Windows XP, Vista and 7 include the command taskkill [5] to terminate processes. The usual syntax for this command is taskkill /im "IMAGENAME".

pkill (see pgrep) is a command-line utility initially written for use with the Solaris 7 operating system in 1998. It has since been reimplemented for Linux and some BSDs. As with the kill and killall commands, pkill is used to send signals to processes. The pkill command allows the use of extended regular expression patterns and other matching ...
Linux also calls the threads of this process idle tasks. [2] In some APIs, PID 0 is also used as a special value that always refers to the calling thread, process, or process group. [3] [4] Process ID 1 is usually the init process primarily responsible for starting and shutting down the system. Originally, process ID 1 was not specifically ...
Similarly, the kill(1) command allows a user to send signals to processes. The raise(3) library function sends the specified signal to the current process. Exceptions such as division by zero , segmentation violation ( SIGSEGV ), and floating point exception ( SIGFPE ) will cause a core dump and terminate the program.
Principal among the offered commands are means to forcibly unmount file systems, kill processes, recover keyboard state, and write unwritten data to disk. The magic SysRq key cannot work under certain conditions, such as a kernel panic [ 2 ] or a hardware failure preventing the kernel from running properly.
Unlike kill, xkill does not request that the client process, which may be running on a different machine, be terminated. In fact, the process can continue running without an X connection. Most clients, however, do abort when their X connections are unexpectedly closed.
