3.3.1.1.
/proc/self/
The
/proc/self/
directory is a link to the currently running process. This allows a process to look at
itself without having to know its process ID.
Within a shell environment, a listing of the
/proc/self/
directory produces the same contents as
listing the process directory for that process.
3.3.2.
/proc/bus/
This directory contains information specific to the various buses available on the system. For example,
on a standard system containing PCI and USB buses, current data on each of these buses is available
within a subdirectory within
/proc/bus/
by the same name, such as
/proc/bus/pci/
.
