However, on others such as IRIX, Linux, and FreeBSD, an argument is supplied specifying the name of the process (or processes) to kill. For instance, to kill a process such as an instance of the XMMS music player invoked by xmms, the user would run the command killall xmms. This would kill all processes named xmms, and is equivalent to kill ...
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.
Send the SIGTERM signal to all processes except init (PID 1) e. e: f: Call oom_kill, which kills a process to alleviate an OOM condition f: u: f: t: When using Kernel Mode Setting, switch to the kernel's framebuffer console. [5] If the in-kernel debugger kdb is present, enter the debugger. g: i: g: d: Output a terse help document to the console

The parent may, for example, wait for the child to terminate with the waitpid() function, or terminate the process with kill(). There are two tasks with specially distinguished process IDs: PID 0 is used for swapper or sched , which is part of the kernel and is a process that runs on a CPU core whenever that CPU core has nothing else to do.

A process's execution may result in the generation of a hardware exception, for instance, if the process attempts to divide by zero or incurs a page fault. In Unix-like operating systems, this event automatically changes the processor context to start executing a kernel exception handler .
Once the kernel has started, it starts the init process, [20] a daemon which then bootstraps the user space, for example by checking and mounting file systems, and starting up other processes. The init system is the first daemon to start (during booting) and the last daemon to terminate (during shutdown ).
kill, which sends signals processes by process ID instead of by pattern-matching against the name. renice, which changes the priority of a process. top and htop, which display a list of processes and their resource usage; htop can send signals to processes directly from this list. skill, a command-line utility to send signals or report process ...
