psrinfo(1)
NAME
  psrinfo, pinfo -  Displays processor administration information

SYNOPSIS
  /usr/sbin/psrinfo -n

  /usr/sbin/psrinfo [-v] [processor ...]

  /usr/sbin/psrinfo -s processor

  /usr/sbin/pinfo [-v] [processor ...]

DESCRIPTION
  The psrinfo and pinfo commands display information about processors.	The
  processor variable specifies the processor identification number, which is
  a unique integer that identifies the processor.  If you do not specify any
  flags or a processor identification number, the commands display
  information about all processors.

FLAGS
  -n	    Displays the number of processors in the system.

  -v	    Enables verbose mode.

  -s	    Writes only a boolean value to standard output.  The -s flag
	    requires a single processor identification number (processor).
	    The -s flag is intended to be used in scripts.  A value of 1 is
	    output if the specified processor is on line.  A value of 0 is
	    output if the specified processor is off line.

EXAMPLES
  The following is an example of the default prsinfo command output (no flags
  or processor identification numbers):

       processor 0 online      since 09/15/1994 17:24:30
       processor 1 offline     since 09/16/1994 09:18:22

  The following example shows how to use the psrinfo command with the -s flag
  in a shell script to determine the state of the processor with an
  identification number of 1:

       if [ "`psrinfo -s 1 2> /dev/null`" -eq 1 ]
       then
	       echo "processor 1 is up"
       else
	       echo "processor 1 is down"
       fi
