NAME

kill, broke − terminate process(es)

SYNOPSIS

­kill [ ­-g ] [ ­pid ...  ] [ ­module ...  ]

­broke

DESCRIPTION

­Kill terminates each process (for a numeric process ID pid) or process running a given ­module (for a non-numeric module name), by writing a ­kill message to the corresponding process’s control file in prog(3). The ­-g option causes ­kill to write a ­killgrp message instead, killing all processes in the given process’s process group (see sys-pctl(2)). Processes running a ­module are identified by their ­status file, and the process ID of each such process is printed on standard output. 

A process that incurs an exception (eg, array bounds check) is normally suspended in the ‘broken’ state to allow debugging.  ­Broke kills all such processes owned by the current user, releasing any resources they hold back to the system; it prints their process IDs.
