| Prev | Chapter 4. The /proc Filesystem | Next |
As the file contents throughout the /proc directory provide a look at the state of your system's kernel, which may also be specially configured for a certain purpose, this chapter should not be seen as comprehensive guide to this information. Rather, you should definitely investigate additional sources of information about /proc before tweaking your kernel.
Most of the best /proc documentation is probably already available on your system.
/usr/src/linux-2.4/Documentation/filesystems/proc.txt — Contains assorted, but limited, information about all aspects of /proc.
/usr/src/linux-2.4/Documentation/sysrq.txt — An overview of System Request Key options.
/usr/src/linux-2.4/Documentation/sysctl — A directory containing a variety of sysctl tips, including modifying values that concern the kernel (kernel.txt), accessing filesystems (fs.txt), and virtual memory use (vm.txt).
/usr/src/linux-2.4/Documentation/networking/ip-sysctl.txt — A look at various IP networking options and their meanings to the kernel.
Perhaps the most authoritative information on /proc can be found by reading the kernel source code. Make sure the kernel-source RPM is installed on your system and look in the /usr/src/linux-2.4 directory for the source.
