Hard Disk info.
First,open up terminal from Applications/Accessories/Terminal,and run:
sudo hdparm /dev/sda
Output:
/dev/sda: multcount = 16 (on) IO_support = 0 (default) readonly = 0 (off) readahead = 256 (on) geometry = 19457/255/63, sectors = 312581808, start = 0
CPU info.
cat /proc/cpuinfo
Output example:
processor : 0 vendor_id : AuthenticAMD cpu family : 15 model : 95 model name : AMD Athlon(tm) 64 Processor 3000+ stepping : 2 cpu MHz : 1799.564 cache size : 512 KB fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 syscall nx mmxext fxsr_opt rdtscp lm 3dnowext 3dnow up rep_good extd_apicid pni cx16 lahf_lm svm extapic cr8_legacy bogomips : 3599.12 TLB size : 1024 4K pages clflush size : 64 cache_alignment : 64 address sizes : 40 bits physical, 48 bits virtual power management: ts fid vid ttp tm stc
CPU Temperature
Option 1:
cat /proc/acpi/thermal_zone/THRM/temperature
This requires kernel modules support,and enable this in kernel option.
Option 2:
Install lm-sensors:
sudo apt-get install lm-sensors
Then run:
sensors-detect
there will be some questions and you can answer them all YES.
Now,use this command and you will get cpu temperature:
