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

−nDisplays the number of processors in the system. 

−vEnables verbose mode which provides more information on the processor, such as its type and speed. 

−sWrites 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 specified 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 information 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.
