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

-nDisplays the number of processors in the system. 

-vEnables verbose mode. 

-sWrites 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
