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).  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.
