Description

psrinfo shows information on configured processors. Without arguments, it prints a line for each processor, telling whether it is online or offline, and when that status last changed.

Options

-v

Use verbose mode, showing information on processor type and clock speed.

-s

Use silent mode. Output only 1 or 0 for the specified processor.

Usage

Displays information about the specified processors, or all processors, if none are specified. Without arguments, information on online/offline status and time of last change is given. With the -v argument, information on processor type, floating point unit type, and clock speed are printed as well. If any of this information cannot be determined, it will be printed as ‘‘unknown.’’

The -s argument is provided for convenient use in shell scripts. When -s is specified, psrinfo will output 1 if the specified processor is online, and 0 otherwise.

Examples

To print the verbose status of all processors:

psrinfo -v

Shell usage to determine if a processor is online:

if [ "‘psrinfo -s 3 2> /dev/null‘" -eq 1 ]then    echo "processor 3 is up"fiFiles

/etc/wtmp

records are read to determine last status change time.
