Modprobed-db is a useful utility for users wishing to build a minimal kernel via a make localmodconfig. In a nutshell, this make target creates a config based on the current config and a list of modules you define (that modprobed-db keeps for you). It then disables any module option that is not needed thus not building extraneous modules. This results in a system-specific, streamlined kernel package and footprint as well as reduced compilation times.

Modprobed-db simply logs every module ever probed on the target system to a text-based database ($XDG_CONFIG_HOME/modprobed-db), which can be read directly by make localmodconfig as described above.

IP sets are a framework inside the Linux 2.4.x and 2.6.x kernel which can be administered by the ipset utility. Depending on the type, currently an IP set may store IP addresses, (TCP/UDP) port numbers or IP addresses with MAC addresses in a way which ensures lightning speed when matching an entry against a set.

If you want to

• store multiple IP addresses or port numbers and match against the entire collection using a single iptables rule.

• dynamically update iptables rules against IP addresses or ports without performance penalty.

• express complex IP address and ports based rulesets with a single iptables rule and benefit from the speed of IP sets.

then IP sets may be the proper tool for you.

Procenv is a command-line tool that displays as much detail about itself and its environment as possible. It can be used as a test tool, to understand the type of environment a process runs in, and for comparing system environments.

This package provides a PAM interface using ctypes.

GNU Linux-Libre is a free (as in freedom) variant of the Linux kernel. It has been modified to remove all non-free binary blobs. Configuration options and patches have been applied for use with MNT/Reform systems.

haveged generates an unpredictable stream of random numbers for use by Linux's /dev/random and /dev/urandom devices. The kernel's standard mechanisms for filling the entropy pool may not be sufficient for systems with high needs or limited user interaction, such as headless servers.

haveged runs as a privileged daemon, harvesting randomness from the indirect effects of hardware events on hidden processor state using the HAVEGE algorithm. It tunes itself to its environment and provides the same built-in test suite for the output stream as used on certified hardware security devices.

The quality of the randomness produced by this algorithm has not been proven. It is recommended to run it together with another entropy source like rngd, and not as a replacement for it.

This package provides a renameat2 command that calls the Linux-specific renameat2 system call.

This tool turns ldd into a tree and explains how shared libraries are found or why they cannot be located.

GNU Linux-Libre is a free (as in freedom) variant of the Linux kernel. It has been modified to remove all non-free binary blobs.

This is a port of the FreeBSD userland for Linux provided by the Chimera Linux distribution. Essentially, it is a collection of UNIX tools such as grep, cp, vi, etc. and can be used as an alternative to the corresponding implementations from the GNU project.

This library parses raw Linux kernel trace event formats.

This package provides a FUSE-based file system that provides read and write access to exFAT devices.

Interception Tools provides a composable infrastructure on top of libudev and libevdev. The following utilities are provided:

• udevmon --- monitor input devices for launching tasks

• intercept --- redirect device input events to stdout

• uinput --- redirect device input events from stding to virtual device

• mux --- mux streams of input events

Light is a program to send commands to screen backlight controllers under GNU/Linux. Features include:

• It does not rely on X.

• Light can automatically figure out the best controller to use, making full use of underlying hardware.

• It is possible to set a minimum brightness value, as some controllers set the screen to be pitch black at a value of 0 (or higher).

This package provides the following binaries to drive the Linux Device Mapper multipathing driver:

1. multipath - Device mapper target autoconfig.

2. multipathd - Multipath daemon.

3. mpathpersist - Manages SCSI persistent reservations on dm multipath devices.

4. kpartx - Create device maps from partition tables.

iw is a new nl80211 based CLI configuration utility for wireless devices. It replaces iwconfig, which is deprecated.

The inih (INI Not Invented Here) library is a simple .INI file parser written in C. It's only a couple of pages of code, and it was designed to be small and simple, so it's good for embedded systems. It's also more or less compatible with Python's ConfigParser style of .INI files, including RFC 822-style multi-line syntax and name: value entries.

Tpacpi-bat is a command-line interface to control battery charging on Lenovo ThinkPad models released after 2011, starting with the xx20 series. It can query and set the thresholds at which one or both batteries will start and stop charging, inhibit charging batteries for a set period of time, or force them to discharge when they otherwise would not.

This tool merely exposes ACPI calls provided by the acpi_call Linux kernel module provided by the acpi-call-linux-module package, which must be installed and loaded separately. Only the original vendor firmware is supported.

This package provides a statically linked xfs_repair taken from the xfsprogs package. It is meant to be used in initrds.

psmisc is a set of small utilities that use the proc file system.

• fuser identifies processes using files or sockets;

• killall kills processes by name;

• prtstat prints statistics of a process;

• pslog prints the log file(s) of a process;

• pstree shows the currently running processes as a tree;

• peekfd shows the data travelling over a file descriptor.

Util-linux is a diverse collection of Linux kernel utilities. It provides dmesg and includes tools for working with file systems, block devices, UUIDs, TTYs, and many other tools.
