The sysctl() system call can get or set the state of the system, the FreeBSD kernel exposes the parameters for sysctl() as objects of a Management information Base (MIB).

sysctltui is a Text User Interface sysctl MIB explorer. It allow to view a parameter’s properties and get or set its value. The first version 0.0.1 is out.

Getting Started

# pkg install sysctlmibinfo2 bsddialog
% git clone https://gitlab.com/alfix/sysctltui.git
% cd sysctltui
% make
% ./sysctltui

The utility provides three windows: a main one with the tree, one to view information about the parameter, and one to set a new value.

Main Window:

Parameter Properties:

Set Value:

Usage

% ./sysctltui -h
usage: sysctltui [-h|v]
       sysctltui [-d|V] [-f] [-e <label>] [-l <label>] [-i <indent>] [-s <label>]

 -d		Show parameter descriptions in the main window.
 -e <label>	Set prefix for nodes with expandable subtree.
 -f		Display full parameter names in the main window.
 -h		Show this help message and exit.
 -i <indent>	Set the visual depth of subtrees.
 -l <label>	Set prefix for leaf nodes.
 -s <label>	Set prefix for nodes with expanded subtrees.
 -V		Display parameter values in the main window.
 -v		Show version and exit.

Tip, layout similar to sysctl or sysutils/nsysctl:

sysctltui is still in its early stages; it is currently at version 0.0.1. It provides some functionality similar to nsysctl and sysctlview, but many features still need to be implemented.

TODO list:

• Add: [View] menu: Rebuild Tree, Expande Tree, Collapse Tree, Show desc, Show Value, Clear screen.
• Add: kelvin format.
• Add: Opaque(s).
• Improve: sort children.
• Add: /etc/sysctl.conf and /boot/loader.conf.

Suggestions, feedback, and new ideas are welcome.
