NAME
       captree - display tree of process capabilities

SYNOPSIS
       captree [OPTIONS]  [(pid|glob-name) ...]

DESCRIPTION
       captree displays the capabilities on the mentioned processes indicated
       by pid or glob-name value(s) given on the command line. If no pid etc
       values are supplied, pid=1 is implied. A pid value of 0 displays all
       the processes known to the kernel.

       The POSIX.1e capabilities are displayed in double quotes in the
       cap_from_text(3) format. The IAB tuple of capabilities is displayed
       between square brackets in the text format described in cap_iab(3).
       Both of these text formats are described in cap_text_formats(7).	 Note,
       the IAB tuple text is omitted if it contains empty A and B components.
       This is because the regular POSIX.1e text contains information about
       the Inheritable flag already. This behavior can be overridden with the
       --verbose command line argument.

       Optional arguments (which must precede the list of pid|glob-name
       values):

       --help Displays usage information and exits. Note, modern Go runtimes
	      exit with status 0 in this case, but older runtimes exit with
	      status 2.

       --verbose
	      Displays capability sets and IAB tuples even when they are
	      empty, or redundant.

       --depth=n
	      Displays the process tree to a depth of n.  Note, the default
	      value for this parameter is 0, which implies infinite depth.

       --colo[u]r=false
	      Colo[u]rs the targeted PIDs, if stdout is a TTY, in red. This
	      option defaults to true when running via a TTY. The
	      --color=false argument will suppress this color. Piping the
	      output into some other program will also suppress the use of
	      colo[u]r.

EXIT STATUS
       If the supplied target cannot be found the exit status is 1. Should an
       unrecognized option be provided, the exit status is 2. Otherwise,
       captree exits with status 0.
