I am not going to discuss why you need strong passwords. It is an open secret that strong passwords keep you relatively safer.

Generating strong passwords is something you can do on your own but putting all the combination of lower and upper cases, numbers, symbols can be a tiresome work.

But you need not worry. Linux has got you covered. We’ll see 5 best password generators for Linux that will ease the task for you.

Creates GPG encrypted, compressed backups; client-side encryption allows to upload the backup onto untrusted servers.

Encrypted backups with a clean and simple interface; easy to use and set up; possibility to mount the backup archive with FUSE and inspect it as a regular file system.

"Recursive directory listing command that produces a depth indented listing of files".

"A minimal implementation of the UNIX tree command with colors!"

gcp is an advanced file copier tool, heavily inspired from the traditional cp command utility, but with some additional features. Displays the copy progress indicator, with estimated time, current file speed; logs of all actions; resume of interrupted copy processes.

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".
