NAME

     ioreg -- show I/O Kit registry

SYNOPSIS

     ioreg [-abfilrtx] [-c class] [-d depth] [-k key] [-n name] [-p plane] [-w width]

DESCRIPTION

     ioreg displays the I/O Kit registry.  It shows the heirarchical registry structure as an inverted tree.  The provider-client relationships
     among those objects is shown as follows:

     +-o provider
       |
       +-o client

     By default, object properties are not shown.  The use of the -c, -k, -l, or -n options cause ioreg to show properties for objects that match
     the specified criteria.

     By supplying the -r option, the user may specify the object which will appear at the root of the tree with the -c, -k, or -n options.  If
     root matches more than one object, multiple trees will be displayed.

     The options are as follows:

     -a    Archive the output in XML.

     -b    Show the object name in bold.

     -c    Show the object properties only if the object is an instance of, or derives from, the specified C++ class (e.g. IOService).

     -d    Limit tree traversal to the specified depth.  The depth limit is applied with respect to each subtree root individually.  Therefore,
	   supplying a depth of 1 will cause ioreg to display only (sub)tree root nodes; children will not be shown.

     -f    Enable smart formatting.  ioreg knows how to format certain properties so that the output is more readable and meaningful, decoding
	   data fields where appropriate.  Currently supported are `reg', `assigned-addresses', `slot-names', `ranges', `interrupt-map', `inter-
	   rupt-parent`, and `interrupts'.

     -i    Show the object inheritance.

     -k    Show the object properties only if the object has the specified key.  Substrings do not match; the specified key must be a full prop-
	   erty name.

     -l    Show properties for all displayed objects.

     -n    Show the object properties only if the object has the specified name.  The object location, if any, is considered part of the name,
	   thus pci@f0000000 and pci@f4000000 are distinct names.

     -p    Traverse the registry over the specified plane.  The default plane value is ``IOService''.  The other planes, such as ``IODeviceTree'',
	   can be found under the ``IORegistryPlanes'' property of the root object (ioreg -d 1 -k IORegistryPlanes).

     -r    Show subtrees rooted by objects that match the specified criteria.  If none of -c, -k, or -n are supplied, -r has no effect.

     -t    Show tree location of each subtree.	This option causes ioreg to display all nodes between the I/O Kit Root and the root of the dis-
	   played subtree, i.e. the subtree's parent, grandparent, etc.

     -w    Clip the output to the specified line width.  The default width value is the current screen size.  A value of 0 specifies an unlimited
	   line width.

     -x    Show data and numbers as hexadecimal.

NAME

       pstree - display a tree of processes

SYNOPSIS

       pstree [-a] [-c] [-h|-Hpid] [-l] [-n] [-p] [-u] [-G|-U] [pid|user]
       pstree -V

DESCRIPTION

       pstree  shows  running  processes  as  a tree. The tree is rooted at either pid or init if pid is omitted. If a user name is specified, all
       process trees rooted at processes owned by that user are shown.

       pstree visually merges identical branches by putting them in square brackets and prefixing them with the repetition count, e.g.

	   init-+-getty
		|-getty
		|-getty
		`-getty

       becomes

	   init---4*[getty]

OPTIONS

       -a     Show command line arguments. If the command line of a process is swapped out, that process is shown in  parentheses.  -a	implicitly
	      disables compaction.

       -c     Disable compaction of identical subtrees. By default, subtrees are compacted whenever possible.

       -G     Use VT100 line drawing characters.

       -h     Highlight the current process and its ancestors. This is a no-op if the terminal doesn't support highlighting or if neither the cur-
	      rent process nor any of its ancestors are in the subtree being shown.

       -H     Like -h, but highlight the specified process instead. Unlike with -h, pstree fails when using -H if highlighting is not available.

       -l     Display long lines. By default, lines are truncated to the display width or 132 if output is sent to a non-tty  or  if  the  display
	      width is unknown.

       -n     Sort processes with the same ancestor by PID instead of by name. (Numeric sort.)

       -p     Show PIDs. PIDs are shown as decimal numbers in parentheses after each process name. -p implicitly disables compaction.

       -u     Show  uid  transitions.  Whenever the uid of a process differs from the uid of its parent, the new uid is shown in parentheses after
	      the process name.

       -U     Use UTF-8 (Unicode) line drawing characters. Under Linux 1.1-54 and above, UTF-8 mode  is  entered  on  the  console  with  echo	-e
	      '33%8' and left with echo -e '33%@'

       -V     Display version information.

       -s     (Flask) Show Security ID (SID) for each process.

       -x     (Flask) Show security context for each process.

FILES

       /proc	 location of the proc file system
