psrinfo(1)							   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...]

OPTIONS

  -n  Displays the number of processors	in the system.

  -v  Enables verbose mode which provides more information on the processor,
      such as its type and speed.

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

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
  options or a processor identification	number,	the commands display informa-
  tion about all processors.

RESTRICTIONS

  The -v correctly reports processor speeds on system that contains mixed-
  speed	CPUs, but the processor	type might not be reported correctly.

EXAMPLES

   1.  The following is	an example of the default prsinfo command output (no
       options or processor identification numbers):



	    greene:> psrinfo
	    0	    on-line   since 11/03/1999 09:41:34
	    1	    on-line   since 11/03/1999 09:41:34
	    2	    off-line  since 11/03/1999 08:41:34



   2.  The following example shows how to use the psrinfo command with the -s
       option 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

   3.  The following example shows how to use the psrinfo command with the -v
       option:


	    % psrinfo -v
	    Status of processor	0 as of: 05/23/00 15:47:40
	      Processor	has been on-line since 05/23/2000 15:08:04
	      The alpha	EV5.6 (21164A) processor operates at 465 MHz,
		    and	has an alpha internal floating point processor.
	    Status of processor	1 as of: 05/23/00 15:47:40
	      Processor	has been on-line since 05/23/2000 15:08:04
	      The alpha	EV5.6 (21164A) processor operates at 465 MHz,
		    and	has an alpha internal floating point processor.
	    Status of processor	2 as of: 05/23/00 15:47:40
	      Processor	has been off-line since	05/23/2000 15:08:04
	      The alpha	EV5.6 (21164A) processor operates at 465 MHz,
		    and	has an alpha internal floating point processor.
	    Status of processor	3 as of: 05/23/00 15:47:40
	      Processor	has been on-line since 05/23/2000 15:14:00
	      The alpha	EV5.6 (21164A) processor operates at 465 MHz,
		    and	has an alpha internal floating point processor.
