Rogue-like game derived from nethack offering extra features, monsters, and items; includes a GUI version.

Secure and simple terminal sharing.

Terminal multiplexer; born to improve screen; client-server architecture, vi and emacs key-bindings, search in window feature and many more.

A fork of tmux that allows to share the terminal with other users. AFAIK, it connects to a centralized server to establish the connection. Someone may see this inconvenient for privacy issues.

Terminal multiplexer that split a physical terminal between several processes, typically interactive shells.

A text-based window manager and terminal multiplexer; it features enhanced profiles, convenient keybindings, configuration utilities, and toggle-able system status notifications; compatible with screen and tmux.

Periodically runs a command in the console while temporarily clearing the screen content; it makes it easy to check differences between the output of two subsequent commands; it provides "diff" functionality to highlight the changing characters between outputs.

The classical Unix utility that provides a rolling display of top cpu using processes.

Python program that reports memory usage; it can report the "proportional set size" (PSS), a meaningful representation of the amount of memory used by libraries and applications in a virtual memory system; it has built-in chart generation.

A top-like utility to monitor the sources of power consumption; allows to turn on/off many components; quite useful to track possible power-related issues.

ngrep applies the grep logic to the network layer, allowing to match regular expressions against data payloads of packets; it recognizes IPv4/6, TCP, UDP, ICMPv4/6, IGMP and Raw across Ethernet, PPP, SLIP, FDDI, Token Ring and null interfaces.

A command to open multiple log files in a single terminal window and monitor them in real-time.

An interactive process viewer for Unix; improves the UI of top, by adding real-time meters and colors.

"A Python program with a top like UI used to show of behalf of which process is the I/O going on".

A comprehensive system information script; provides information about CPU, graphics, audio and network devices, drives and partitions, sensors; implemented as a Bash script.

A program to turn CLI tools into web applications; basically, it runs a command and starts a server so that the output can be displayed in a web page.

A comprehensive and detailed system monitoring tool; monitored parameters include: CPU, memory, load, process list, network interfaces, disk I/O, sensors, filesystems, docker, system info, uptime.

"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".

Alternative shell designed for interactive use.

Focused on user-friendliness, with powerful autosuggestions, colors, "sane scripting" (w.r.t. to Bash).
