This package provides statically-linked fsck.f2fs command taken from the f2fs-tools package. It is meant to be used in initrds.

libnetfilter_cthelper is a userspace library that provides a programming interface to user-space connection tracking helpers.

1. register new user-space connection tracking helpers

2. unregister user-space connection tracking helpers

3. list existing registered user-space connection tracking helpers

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

ulogd is a userspace logging daemon for netfilter/iptables related logging. This includes per-packet logging of security violations, per-packet logging for accounting, per-flow logging and flexible user-defined accounting.

1. Packet and flow-based traffic accounting

2. Flexible user-defined traffic accounting via nfacct infrastructure

3. SQL database back-end support: SQLite3, PostgreSQL, MySQL

4. Text-based output formats: CSV, XML, Netfilter's LOG, Netfilter's conntrack

This package contains utilities for accessing the powercap Linux kernel feature through sysfs. It includes an implementation for working with Intel RAPL. It provides the commands powercap-info and powercap-set.

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.

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.

fbcat saves the contents of the Linux framebuffer (/dev/fb*), or a dump thereof. It supports a wide range of drivers and pixel formats.

fbcat can take screenshots of virtually any application that can be made to write its output to the framebuffer, including (but not limited to) text-mode or graphical applications that don't use a display server.

Also included is fbgrab, a wrapper around fbcat that emulates the behaviour of Gunnar Monell's older fbgrab utility.

Wireless Tools are used to manipulate the now-deprecated Linux Wireless Extensions; consider using iw instead. The Wireless Extension was an interface allowing you to set Wireless LAN specific parameters and get the specific stats. It is deprecated in favor the nl80211 interface.

The bbswitch module provides a way to toggle the Nvidia graphics card on Optimus laptops.

This package provides utilities for testing, partitioning, etc of flash storage.

pflask is a simple tool for creating Linux namespace containers. It can be used for running a command or even booting an OS inside an isolated container, created with the help of Linux namespaces. It is similar in functionality to chroot, although pflask provides better isolation thanks to the use of namespaces.

LVM2 is the logical volume management tool set for Linux-based systems. This package includes the user-space libraries and tools, including the device mapper. Kernel components are part of Linux-libre.

This package provides userspace components for the InfiniBand subsystem of the Linux kernel. Specifically it contains userspace libraries for the following device nodes:

1. /dev/infiniband/uverbsX (libibverbs)

2. /dev/infiniband/rdma_cm (librdmacm)

3. /dev/infiniband/umadX (libibumad)

The following service daemons are also provided:

1. srp_daemon (for the ib_srp kernel module)

2. iwpmd (for iWARP kernel providers)

3. ibacm (for InfiniBand communication management assistant)

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.

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.

The libiec61883 library provides a higher level API for streaming DV, MPEG-2 and audio over Linux IEEE 1394.

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.

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.

Udev is a daemon which dynamically creates and removes device nodes from /dev/, handles hotplug events and loads drivers at boot time.

The i2c-tools package contains a heterogeneous set of I2C tools for Linux: a bus probing tool, a chip dumper, register-level SMBus access helpers, EEPROM decoding scripts, EEPROM programming tools, and a python module for SMBus access.

This package provides many of the missing pieces in GNU libc. Most notably the string functions: strlcpy(3), strlcat(3) and the *BSD sys/queue.h and sys/tree.h API's.

This package provides a WiiMote driver that follows the Linux input convention. Specifically, that allows you to use the D-pad as a gamepad.
