 |
|
Hi,
does anybody know how to get the current frequency of the CPU? I already tried "cat /proc/cpuinfo" an "/proc/cpufreq" but that doesn't tell me the *current* speed of my CPU...
TIA |

| it should tell you the clockspeed of the cpu at the time you press enter. |

What do you mean with "it"?
And why do you say "should", isn't that for sure? |

hehe 
ok, a rephrase:
the output of cat /proc/cpuinfo will tell you the current clock speed.
i wonder though - why would you doubt its accuracy? |

/proc/cpuinfo is very inaccurate, at least if the hardware+BIOS support frequency scaling, or they do frequency throttling and _you_ count that as chaning the clock speed.
But leaving that aspect aside, the "best" information on current CPU speed can be found at
| Code: | | /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_speed |
As it involves calls to hardware, this file is only availble to root. |
