/proc is very special in that it is also a virtual filesystem.
Most of the /proc file system is read-only; however, some files allow kernel variable to be changed.
The entries in /proc may change slightly between kernel versions, so if there is any doubt review the kernel documentation in the directory /usr/src/linux/Documentation.
Proc is an in-memory file system used to provide file based communication with the kernel.
Proc create an infrastructure for doing that and creates a simpler interface for kernel components to register files and the corresponding handler (these handlers will provide the actual functionality).
Proc files handling through the read_proc callback has to copy into a proc buffer which will be copied into the user space.
Proc is short for "spec_proc" which is a term used by the original programmer of Circle-MUD, Jeremy Elson.
For weapons that have a proc, they usually have a Chance on Hit to either aid the wielder, harm his target(s) or both.
Worn items such as these can either trigger their proc when the wearer is hit in combat, when the wearer uses the item, or when the wearer hits his opponent with a melee attack.
/proc is a file system that provides access to the state of each process and light-weight process (lwp) in the system.
Although process state and consequently the contents of /proc files can change from instant to instant, a single read.2 of a /proc file is guaranteed to return a sane representation of state; that is, the read will be atomic with respect to the state of the process.
Because the old ioctl.2 version of /proc is currently supported for binary compatibility with old applications, the top-level directory for a process, /proc/pid, is not world-readable, but it is world-searchable.
Proc and its ability to display a wide array of data concerning the runtime state of a system are the focus of our discussion here.
Readers are invited to explore the /proc directory of an available system and consult the proc(5) manual page to solidify their understanding of the above discussion.
As an added measure in checking that we are working with the proc file we think we are, we compare the inode numbers, st_ino, and resident filesystem, st_dev, that both lstat(2) and fstat(2) reported in their /proc/net/dev attribute checks.

Linux: The proc Filesystem - Linux Manual(Site not responding. Last check: 2007-10-21)
As there is no complete documentation for the /proc file system and we've used many freely available sources to write these chapters, it seems only fair to give the work back to the Linux community.
The entries in /proc may change slightly between the 2.1.* and the 2.2 kernel, so if there is any doubt review the kernel documentation in the directory /usr/src/linux/Documentation.
This chapter is heavily based on the documentation included in the pre 2.2 kernels, and became part of it in version 2.2.1 of the Linux kernel.
Any PROC SQL view is expanded into the underlying query, and parentheses are shown around all expressions to further indicate their order of evaluation.
PROC SQL sets the column width at n and specifies that character columns longer than n are flowed to multiple lines.
In that case, PROC SQL issues an error message and does not execute the statement.
The proc filesystem is a pseudo-filesystem which is used as an interface to kernel data structures.
This directory refers to the process accessing the /proc filesystem, and is identical to the /proc directory named by the process ID of the same process.
These variables can be read and sometimes modified using the proc file system, and the sysctl(2) system call.
Proc-HE is the body responsible for developing and implementing the procurement strategy for UK Higher Education.
The Proc-HE Vision is 'working together to develop and promote efficient and effective procurement practices and procedures throughout higher education taking into account social, ethical and environmental issues'.
The Proc-HE Secretariat, together with Procureweb (the sector's procurement community electronic database and communications system), support Proc-HE in delivering the Strategy.
Proc GLM was designed to fit fixed effect models and later amended to fit some random effect models by including RANDOM statement with TEST option.
It also has to be mentioned that PROC GLM was design for analysis of fixed effects models and all computations are done under the assumption that there is only one variance component in the model, the error term.
Values from proc mixed have to be compared with the Tests of Hypotheses for Mixed Model Analysis from proc GLM, not with the main, General Linear Model Procedure, ANOVA table.
PROC MIGRATE not only copies or moves a library to the target installation, it also changes the members' file format to that of the most recent release of SAS, enabling you to exploit the full capabilities of the software.
Here is one SUGI 28 paper and associated presentation that focus on the role of PROC MIGRATE.
PROC MIGRATE: How to Migrate Your Data and Know You've Done It Right!
The /proc filesystem is one of Linux's great features, and this article gives you a thorough grounding in some of its most useful aspects.
With it, you can administer many details of the operating system without ever having to shut down and reboot the machine, which is a boon for those who need to keep their systems as available as possible.
Learn more about the /proc virtual filesystem from Linux Gazette.
The SignVideo processing amplifiers (proc amps) are highly recommended for DV, Hi-8, 8, S-VHS, VHS, and betacam and for both linear and non-linear editing
Use our proc amps to correct shot by shot for brightness, contrast, color saturation and hue.
Also use our proc amps to match shots from different cameras or taken on different days or under different lighting conditions.
Some of these can be modified by root, but most are read only.
