28.11 The /proc File System
The /proc file system is a pseudo file system in which the kernel reserves
important information in the form of virtual files. For example, the CPU
type can be ascertained with this command:
$ cat /proc/cpuinfo
processor : 0
vendor_id : AuthenticAMD
cpu family : 6
model : 8
model name : AMD Athlon(tm) XP 2400+
stepping : 1
cpu MHz : 2009.343
cache size : 256 KB
fdiv_bug : no
[...]
Allocation and use of interrupts:
$ cat /proc/interrupts
