The a<br /> option asks for information about all processes with termi-<br /> nals (ordinarily only one's own processes are displayed); x<br /> asks even about processes with no terminal; l asks for a<br /> long listing. The short listing contains the process ID,<br /> tty letter, the cumulative execution time of the process and<br /> an approximation to the command line.<br /> <br /> The long listing is columnar and contains<br /> <br /> F Flags associated with the process. 01: in memory; 02:<br /> system process; 04: locked in memory (e.g. for physical<br /> I/O); 10: being swapped; 20: being traced by another<br /> process; 200: partially swapped.<br /> <br /> S The state of the process. 0: nonexistent; S: sleeping;<br /> W: waiting; R: running; I: intermediate; Z: terminated;<br /> T: stopped.<br /> <br /> UID The user ID of the process owner.<br /> <br /> PID The process ID of the process; as in certain cults it<br /> is possible to kill a process if you know its true<br /> name.<br /> <br /> PPID The process ID of the parent process.<br /> <br /> CPU Processor utilization for scheduling.<br /> <br /> PRI The priority of the process; high numbers mean low<br /> priority.<br /> <br /> NICE Used in priority computation.<br /> <br /> ADDR The memory address of the process if resident, other-<br /> wise the disk address.<br /> <br /> SZ The size in blocks of the memory image of the process.<br /> <br /> WCHAN<br /> The event for which the process is waiting or sleeping;<br /> if blank, the process is running.<br /> <br /> TTY The controlling tty for the process.<br /> <br /> TIME The cumulative execution time for the process.<br /> <br /> The command and its arguments.<br /> <br /> A process that has exited and has a parent, but has not yet<br /> been waited for by the parent is marked &lt;defunct&gt;. _P_s makes<br /> an educated guess as to the file name and arguments given<br /> when the process was created by examining memory or the swap<br /> area. The method is inherently somewhat unreliable and in<br /> any event a process is entitled to destroy this information,<br /> so the names cannot be counted on too much.<br /> <br /> If the k option is specified, the file /_u_s_r/_s_y_s/_c_o_r_e is used<br /> in place of /_d_e_v/_k_m_e_m. This is used for postmortem system<br /> debugging. If a second argument is given, it is taken to be<br /> the file containing the system's namelist.<br /> <br /> == FILES ==<br /> /unix system namelist<br /> /dev/kmem kernel memory<br /> /usr/sys/core alternate core file<br /> /dev searched to find swap device and tty names<br /> <br /> == SEE ALSO ==<br /> [[32v 1m kill|kill(1)]]<br /> <br /> == BUGS ==<br /> Things can change while _p_s is running; the picture it gives<br /> is only a close approximation to reality.<br /> Some data printed for defunct processes is irrelevant.<br /> <br /> [[Category:32v man section 1]]</div>
