system configuration and diagnostic information on Linux systems

prtdiag displays system configuration and diagnostic information on Linux systems.




 Especially on x86 platforms many information is aquired by reading the appropriate values from BIOS using dmidecode(8) and biosdecode(8) from the dmidecode package, which require super user privileges. Therefore this script should be run as super user (aka root).
Furthermore this script utilizes the sysfs of Linux 2.6.x or better kernels, especially for retrieving SCSI and hardware sensor information. It expects the sysfs to be mounted on the /sys directory. NOTE: This script does not try to setup or load any hardware monitoring kernel modules - so the lm_sensors utilities are not used. However you may use its sensors-detect(8) as well as the i2c-detect(8) utilities to find out, which modules are appropriate for your hardware and how to load them automatically at startup.

Options

-f         display all temperatures values in Fahrenheit instead of Celsius.

 

-h       display a short usage summary and exit.

-H      Do not display the report header (which usually consists of the hostname and time of    execution of the script).

-V     display version and copryright information and exit.

-t       types




A simple string, which indicates, what system information should be displayed. The following letters are honored:


g    general platform

c    CPUs

p    PCI (especially IO) devices

i     IDE devices

s    SCSI devices

m   memory devices

e    environment (i.e. fan speeds, temperatures, voltages)

b    BIOS/PROM version

a    all (default)
