Re: can i copy /proc

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



mkdir proc
cp /proc/cpuinfo proc

works for me.

So just out of curiosity, what do you hope to accomplish?

yes.

but i want to copy this file to have the parameter setting in this computer
eg: cpuinfo ... interrupt....

how can I copy this file?


which part of THEY ARE NOT FILES are you missing here?

everything in linux is a file: directories, printers, sockets, named pipes etc.


thats the kernel reporting the ACTUAL cpuinfo. you can''t change that. ditto interrupts, etc.

$ cat /proc/interrupts
          CPU0       0: 2214281030          XT-PIC  timer
 1:          2          XT-PIC  i8042
 2:          0          XT-PIC  cascade
 6:          6          XT-PIC  floppy
 7:          1          XT-PIC  parport0
 8:          1          XT-PIC  rtc
 9:          1          XT-PIC  acpi, uhci_hcd:usb2
11:     218548          XT-PIC  eth0
12:          1          XT-PIC  uhci_hcd:usb1
14:    4659843          XT-PIC  ide0
15:   19337609          XT-PIC  ide1
NMI:          0
LOC:          0

what possible sense would 'copying' that to another system make? I go to a different computer...

 # cat /proc/interrupts
          CPU0       0: 1078260604          XT-PIC  timer
 1:          3          XT-PIC  keyboard
 2:          0          XT-PIC  cascade
 7:          0          XT-PIC  usb-ohci
 8:          1          XT-PIC  rtc
 9:   75485990          XT-PIC  aic7xxx
10: 1754046926          XT-PIC  eth0
14:        131          XT-PIC  ide0
NMI:          0
ERR:          0

and the different devices are on different IRQs, never mind the IRQ counts being different.

anyways, most of whats in /proc is readonly.
