NAME

sysctltui — TUI utility to get or set system state

SYNOPSIS

DESCRIPTION

The sysctltui utility provides a text user interface (TUI) for retrieving and modifying system state at runtime. System parameters are exposed as objects of a “Management Information Base” (MIB). sysctltui sysctltui allows users to navigate the MIB, display the properties of a parameter, and retrieve or modify its value.

sysctltui requires the sysctlinfo(4) interface. To load the required kernel module at boot time, place the following line in loader.conf(5):

sysctlinfo_load="YES"

The following options are available:

-d

Show parameter descriptions in the main window.

-e label

Set label as prefix for nodes with expandable subtree, default “+”.

-f

Display full parameter names in the main window. The full name of the parameter currently in focus within the main window is no longer shown at the bottom of the screen.

-h

Print a help message and exit.

-i indent

Set indent as the visual depth of subtrees.

-l label

Set label as prefix for leaf nodes, default no string.

-s label

Set label as prefix for nodes with expanded subtrees, default “-”.

-V

Display parameter values in the main window

-v

Print version and quit.

EXIT STATUS

The sysctltui utility exits 0 on success, and >0 if an error occurs.

COMPATIBILITY

Layout similar to sysctl(8) and nsysctl(8):

% [n]sysctl -a           % sysctltui -fV -i 0
% [n]sysctl -an          % sysctltui -f -i 0
% [n]sysctl -ad          % sysctltui -fd -i 0
