CAPTREE(8) System Manager's Manual CAPTREE(8) 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 un- recognized option be provided, the exit status is 2. Otherwise, captree ex- its with status 0.
