  12. acpid listens to ACPI events coming either in textual form from
  13. /proc/acpi/event (though it is marked deprecated it is still widely
  14. used and _is_ a standard) or in binary form from specified evdevs
  15. (just use /dev/input/event*).
  16. It parses the event to retrieve ACTION and a possible PARAMETER.
  17. It then spawns /etc/acpi/<ACTION>[/<PARAMETER>] either via run-parts
  18. (if the resulting path is a directory) or directly as an executable.

  40. dmesg is used to examine or control the kernel ring buffer. When the
  41. Linux kernel prints messages to the system log, they are stored in
  42. the kernel ring buffer. You can use dmesg to print the kernel's ring
  43. buffer, clear the kernel ring buffer, change the size of the kernel
  44. ring buffer, and change the priority level at which kernel messages

  96. fdflush is only needed when changing media on slightly-broken
  97. removable media drives. It is used to make Linux believe that a
  98. hardware disk-change switch has been actuated, which causes Linux to
  99. forget anything it has cached from the previous media. If you have
  100. such a slightly-broken drive, you will need to run fdflush every time

  195. Linux allows you to create ramdisks. This utility allows you to

  640. your stripped-down embedded system does not have a /proc directory.
  641. If you must use this, keep in mind it's inherently brittle (for
  642. example a mount under chroot won't update it), can't handle modern
