NAME

ps, psu - process status

SYNOPSIS

ps [ -apr ]

psu [ -apr ] [ 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.
no resource: waiting for more of a critical resource.

The -r flag causes ps to print, before the user time, the elapsed real time for the process.

The -p flag causes ps to print, after the system time, the baseline and current priorities of each process.

The -a flag causes ps to print the arguments for the process. Newlines in arguments will be translated to spaces for display.
