NAME

       ps, psu - process status

SYNOPSIS

       ps

       psu [ user ]

DESCRIPTION

       Ps prints information about processes.  Psu prints only information about processes started by user (default $user).

       For  each  process  reported, the user, process id, user time, system time, size, state, and command name are printed.  State is one of the
       following:

       Moribund      Process has exited and is about to have its resources reclaimed.

       Ready	     on the queue of processes ready to be run.

       Scheding      about to be run.

       Running	     running.

       Queueing      waiting on a queue for a resource.

       Wakeme	     waiting for I/O or some other kernel event to wake it up.

       Broken	     dead of unnatural causes; lingering so that it can be examined.

       Stopped	     stopped.

       Stopwait      waiting for another process to stop.

       Fault	     servicing a page fault.

       Idle	     waiting for something to do (kernel processes only).

       New	     being created.

       Pageout	     paging out some other process.

       Syscall	     performing the named system call.

NAME

       ps - process status

SYNOPSIS

       ps [-alxU] [kernel mm fs]

OPTIONS

       -a     Print all processes with controlling terminals

       -l     Give long listing

       -x     Include processes without a terminal

EXAMPLES

       ps -axl		   # Print all processes and tasks in long format

DESCRIPTION

       Ps  prints the status of active processes.  Normally only the caller's own processes are listed in short format (the PID, TTY, TIME and CMD
       fields as explained below).  The long listing contains:

	 F  Kernel flags:	    001: free slot	     002: no memory map 	  004: sending; 	   010:  receiving	      020:
       inform on pending signals	   040: pending signals 	  100: being traced.

	 S	 State: 	   R: runnable		 W: waiting (on a message)	     S: sleeping (i.e.,suspended on MM or FS)		Z:
       zombie		T: stopped

	 UID, PID, PPID, PGRP	   The user, process, parent process and process group ID's.

	 SZ	 Size of the process in kilobytes.

	 RECV	   Process/task on which a receiving process is waiting or sleeping.

	 TTY	       Controlling tty for the process.

	 TIME	   Process' cumulative (user + system) execution time.

	 CMD	 Command line arguments of the process.

       The files /dev/{mem,kmem} are used to read the system tables and command line arguments from.  Terminal names in /dev are used to  generate
       the mnemonic names in the TTY column, so ps is independent of terminal naming conventions.
