A program that looks for coreutils basic commands (cp, mv, dd, tar, gzip/gunzip, cat, etc.) currently running on your system and displays the percentage of copied data. It can also show estimated time and throughput, and provides a "top-like" mode (monitoring).

This package provides a tiny system info utility.

Dstat is a versatile replacement for vmstat, iostat, netstat, and ifstat. Dstat overcomes some of their limitations and adds some extra features, more counters and flexibility. Dstat is handy for monitoring systems during performance tuning tests, benchmarks or troubleshooting.

Dstat allows you to view all of your system resources in real-time, you can, e.g., compare disk utilization in combination with interrupts from your IDE controller, or compare the network bandwidth numbers directly with the disk throughput (in the same interval).

UDPcast is a file transfer tool that can send data simultaneously to many destinations on a LAN. This can for instance be used to install entire classrooms of PC's at once. The advantage of UDPcast over using other methods (nfs, ftp, whatever) is that UDPcast uses UDP's multicast abilities: it won't take longer to install 15 machines than it would to install just 2.

Btop++ provides unified monitoring of CPU, memory, network and processes.

wpa_supplicant is a WPA Supplicant with support for WPA and WPA2 (IEEE 802.11i / RSN). Supplicant is the IEEE 802.1X/WPA component that is used in the client stations. It implements key negotiation with a WPA Authenticator and it controls the roaming and IEEE 802.11 authentication/association of the WLAN driver.

This package provides the wpa_supplicant daemon and the wpa_cli command.

di is a disk information utility, displaying everything that your df command does and more. It features the ability to display your disk usage in whatever format you prefer. It is designed to be highly portable and produce uniform output across heterogeneous networks.

This package provides a daemon for checking running and not running processes. It reads the /proc directory every n seconds and does a POSIX regexp on the process names. The daemon runs a user-provided script when it detects a program in the running processes, or an alternate script if it doesn't detect the program. The daemon can only be called by the root user, but can use sudo -u user in the process called if needed.

Pam-mount is a PAM module to mount volumes when a user logs in. It can mount all local file systems supported by mount, as well as LUKS volumes encrypted with the user's log-in password.

This is htop, an interactive process viewer. It is a text-mode application (for console or X terminals) and requires ncurses.

Nmap ("Network Mapper") is a network discovery and security auditing tool. It is also useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. It also provides an advanced netcat implementation (ncat), a utility for comparing scan results (ndiff), and a packet generation and response analysis tool (nping).

The Cactus File Manager (cfm) helps you manage your files visually from a text terminal. It aims to be simple and fast, with key bindings inspired by vi.

Munge is an authentication service for creating and validating credentials. It allows a process to authenticate the UID and GID of another local or remote process within a group of hosts having common users and groups. These hosts form a security realm that is defined by a shared cryptographic key. Clients within this security realm can create and validate credentials without the use of root privileges, reserved ports, or platform-specific methods.

greetd is a minimal and flexible login manager daemon that makes no assumptions about what you want to launch.

If you can run it from your shell in a TTY, greetd can start it.

If it can be taught to speak a simple JSON-based IPC protocol, then it can be a greeter.

Fastfetch is a tool for fetching system information and displaying it in a stylized way. Fastfetch displays this information next to a logo of the system distribution, akin to many similar tools.

AIDE (Advanced Intrusion Detection Environment) is a file and directory integrity checker. It creates a database from the regular expression rules that it finds from its configuration files. Once this database is initialized it can be used to verify the integrity of the files. It has several message digest algorithms that are used to check the integrity of files. All of the usual file attributes can be checked for inconsistencies.

wpa_supplicant is a WPA Supplicant with support for WPA and WPA2 (IEEE 802.11i / RSN). Supplicant is the IEEE 802.1X/WPA component that is used in the client stations. It implements key negotiation with a WPA Authenticator and it controls the roaming and IEEE 802.11 authentication/association of the WLAN driver.

This package provides the wpa_supplicant daemon and the wpa_cli command.

hungrycat prints the contents of a file to standard output, while simultaneously freeing the disk space it occupied. It is useful if you need to process a large file, don't have enough space to store both the input and output files, and don't need the input file afterwards. While similar in principle to running cat immediately followed by rm, hungrycat actually frees blocks as soon as they are printed instead of after the entire file has been read, which is often too late.

This package provides a simple, configurable system information tool.

Bash screenshot information tool which can be used to generate those nifty terminal theme information and ASCII distribution logos in everyone's screenshots nowadays.

ngrep is like GNU grep applied to the network layer. It's a PCAP-based tool that allows you to specify an extended regular or hexadecimal expression to match against data payloads of packets. It understands many kinds of protocols, including IPv4/6, TCP, UDP, ICMPv4/6, IGMP and Raw, across a wide variety of interface types, and understands BPF filter logic in the same fashion as more common packet sniffing tools, such as tcpdump and snoop.

Neofetch is a command-line system information tool written in Bash. Neofetch displays information about your system next to an image, your OS logo, or any ASCII file of your choice. The main purpose of Neofetch is to be used in screenshots to show other users what operating system or distribution you are running, what theme or icon set you are using, etc.

Dool is a command line tool to monitor many aspects of your system: CPU, Memory, Network, Load Average, etc. It also includes a robust plug-in architecture to allow monitoring other system metrics.

Stress is a tool that imposes a configurable amount of CPU, memory, I/O, or disk stress on a POSIX-compliant operating system and reports any errors it detects.

Stress is not a benchmark. It is a tool used by system administrators to evaluate how well their systems will scale, by kernel programmers to evaluate perceived performance characteristics, and by systems programmers to expose the classes of bugs which only or more frequently manifest themselves when the system is under heavy load.
