<p><font size=+1><b>DESCRIPTION </b></font><br>
<table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td>
<i>Ps</i> prints information about processes. <i>Psu</i> prints only information
about processes started by <i>user</i> (default <tt><font size=+1>$USER</font></tt>).
<table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
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:<br>
<tt><font size=+1>Moribund</font></tt> Process has exited and is about to have its resources
reclaimed.<br>
<tt><font size=+1>Ready</font></tt> on the queue of processes ready to be run.<br>
<tt><font size=+1>Scheding</font></tt> about to be run.<br>
<tt><font size=+1>Running</font></tt> running.<br>
<tt><font size=+1>Queueing</font></tt> waiting on a queue for a resource.<br>
<tt><font size=+1>Wakeme</font></tt> waiting for I/O or some other kernel event to wake it up.<br>
<tt><font size=+1>Broken</font></tt> dead of unnatural causes; lingering so that it can be examined.<br>
<tt><font size=+1>Stopped</font></tt> stopped.<br>
<tt><font size=+1>Stopwait</font></tt> waiting for another process to stop.<br>
<tt><font size=+1>Fault</font></tt> servicing a page fault.<br>
<tt><font size=+1>Idle</font></tt> waiting for something to do (kernel processes only).<br>
<tt><font size=+1>New</font></tt> being created.<br>
<tt><font size=+1>Pageout</font></tt> paging out some other process.<br>
<i>Syscall</i> performing the named system call.<br>
<tt><font size=+1>no</font></tt> <i>resource</i> waiting for more of a critical <i>resource</i>.<br>
<i>wchan</i> waiting on the named wait channel (on a Unix kernel).
<table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
With the <tt><font size=+1>−p</font></tt> flag, <i>ps</i> also prints, after the system time, the baseline
and current priorities of each process.
<table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
The <tt><font size=+1>−a</font></tt> flag causes <i>ps</i> to print the arguments for the process.
Newlines in arguments will be translated to spaces for display.<br>
