CAPTREE(8) System Manager's Manual CAPTREE(8)
captree - display tree of process capabilities
captree [OPTIONS] [(pid|glob-name) ...]
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). 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.
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.
