The SIGSEGV signal is sent to a process when it makes an invalid virtual memory reference, or segmentation fault, i.e. when it performs a segmentation violation. [19] SIGSTOP The SIGSTOP signal instructs the operating system to stop a process for later resumption. SIGSYS The SIGSYS signal is sent to a process when it passes a bad argument to a ...

This sends the "terminal stop" signal (SIGTSTP) to the process group. By default, SIGTSTP causes processes receiving it to stop, and control is returned to the shell. However, a process can register a signal handler for or ignore SIGTSTP. A process can also be paused with the "stop" signal (SIGSTOP), which cannot be caught or ignored.
If the process receiving SIGHUP is a Unix shell, then as part of job control it will often intercept the signal and ensure that all stopped processes are continued before sending the signal to child processes (more precisely, process groups, represented internally by the shell as a "job"), which by default terminates them.

Kill all processes accessing a file by sending a SIGKILL. Use e.g. -HUP or -1 to send a different signal.-l, --list-signals List all supported signal names.-i, --interactive Prompt before killing a process.-v, --verbose verbose mode-a, --all Display all files. Without this option, only files accessed by at least one process are shown.-m ...
All signals except for SIGKILL and SIGSTOP ("stop") can be "intercepted" by the process, meaning that a special function can be called when the program receives those signals. The two exceptions SIGKILL and SIGSTOP are only seen by the host system's kernel , providing reliable ways of controlling the execution of processes.

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.
