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. 

−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. 

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
