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 includes the important tools for controlling the network subsystem of the Linux kernel. This includes arp, ifconfig, netstat, rarp and route. Additionally, this package contains utilities relating to particular network hardware types (plipconfig, slattach) and advanced aspects of IP configuration (iptunnel, ipmaddr).

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.

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.

Headers of the Linux-Libre kernel.

The mcelog daemon logs memory, I/O, CPU, and other hardware errors on x86 systems running the kernel Linux. It can also perform user-defined tasks, such as bringing bad pages off-line, when configurable error thresholds are exceeded.

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)

As a consequence of its monolithic design, file system code for Linux normally goes into the kernel itself---which is not only a robustness issue, but also an impediment to system extensibility. FUSE, for "file systems in user space", is a kernel module and user-space library that tries to address part of this problem by allowing users to run file system implementations as user-space processes.

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.

WirePlumber is a modular session / policy manager for PipeWire and a GObject-based high-level library that wraps PipeWire's API, providing convenience for writing the daemon's modules as well as external tools for managing PipeWire.

acpid is designed to notify user-space programs of Advanced Configuration and Power Interface (ACPI) events. acpid should be started during the system boot, and will run as a background process. When an ACPI event is received from the kernel, acpid will examine the list of rules specified in /etc/acpi/events and execute the rules that match the event.

The libnl suite is a collection of libraries providing APIs to netlink protocol based Linux kernel interfaces. Netlink is an IPC mechanism primarily between the kernel and user space processes. It was designed to be a more flexible successor to ioctl to provide mainly networking related kernel configuration and monitoring interfaces.

This package provides a statically linked ntfsfix taken from the ntfs-3g package. It is meant to be used in initrds.

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.

Dwarves is a set of tools that use the debugging information inserted in ELF binaries by compilers such as GCC, used by well known debuggers such as GDB.

Utilities in the Dwarves suite include pahole, that can be used to find alignment holes in structures and classes in languages such as C, C++, but not limited to these. These tools can also be used to encode and read the BTF type information format used with the kernel Linux bpf syscall.

The codiff command can be used to compare the effects changes in source code generate on the resulting binaries.

The pfunct command can be used to find all sorts of information about functions, inlines, decisions made by the compiler about inlining, etc.

The pahole command can be used to use all this type information to pretty print raw data according to command line directions.

Headers can have its data format described from debugging info and offsets from it can be used to further format a number of records.

Finally, the btfdiff command can be used to compare the output of pahole from BTF and DWARF, to make sure they produce the same results.

F2FS, the Flash-Friendly File System, is a modern file system designed to be fast and durable on flash devices such as solid-state disks and SD cards. This package provides the userland utilities.

Firejail is a SUID sandbox program that reduces the risk of security breaches by restricting the running environment of untrusted applications using Linux namespaces, seccomp-bpf and Linux capabilities. The software includes sandbox profiles for a number of common Linux programs. Firejail should be added to the list of setuid programs in the system configuration to work properly. Builded with --disable-sandbox-check, which is only intended for development.

Libcxi provides applications with a low-level interface to the Cray/HPE Cassini high-speed NIC, also known as Slingshot.

Nvme-cli is a utility to provide standards compliant tooling for NVM-Express drives. It was made specifically for Linux as it relies on the IOCTLs defined by the mainline kernel driver.

ebtables is an application program used to set up and maintain the tables of rules (inside the Linux kernel) that inspect Ethernet frames. It is analogous to the iptables application, but less complicated, due to the fact that the Ethernet protocol is much simpler than the IP protocol.

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.

Tools for loading and managing Linux kernel modules, such as modprobe, insmod, lsmod, and more.

iptables is the user-space command line program used to configure the Linux 2.4.x and later IPv4 packet filtering ruleset (firewall), including NAT (Network Address Translation).

This package also includes ip6tables, which is used to configure the IPv6 packet filter.

Both commands are targeted at system administrators.

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.
