thanks for your advice mr. B10m...
i found that the /proc filesystem is a virtual file...that is why i need to copy the the /proc/cpuinfo into cpuinfo.dat files..
i think that is the better way on how that i can modify the filesystem....
when i copy the virtual file, i hope i can load the value from the copied file into my Perl/GTK application...
anyway,thanks for your advice... :)
mm..sorry friends if this topic is not related to this site...im sorry.. ;)
