FractalNow provides users with tools to generate pictures of various types of fractals quickly and easily. It is made of both a command line tool, FractalNow, and a graphical tool, QFractalNow. The graphical tool, based on Qt library, allows users to explore fractals intuitively and generate pictures. Both tools are entirely multi-threaded and implement advanced algorithms and heuristics that make computation very fast compared to most existing free fractal generators.

Command Line Progress Bar is a simple command line tool to display information about a data transfer stream. It will display the number of bytes transfered, the speed of the transfer, and if the size of the data stream is known it will display the ETA, p

SIGAR (System Information Gatherer and Reporter) is a cross-platform, cross-language library and command-line tool for accessing operating system and hardware level information in Java, Perl and .NET.

Ink is a command line tool which displays the ink level of your printer. It makes use of libinklevel.

A library facilitating complex TUIs on modern terminal emulators, supporting vivid colors, multimedia, threads, and Unicode to the maximum degree possible. Things can be done with Notcurses that simply can't be done with NCURSES. It is furthermore fast as shit. What it is not: a source-compatible X/Open Curses implementation, nor a replacement for NCURSES on existing systems. Notcurses abandons the X/Open Curses API bundled as part of the Single UNIX Specification. For some necessary background, consult Thomas E. Dickey's superb and authoritative NCURSES FAQ. As such, Notcurses is not a drop-in Curses replacement. Wherever possible, Notcurses makes use of the Terminfo library shipped with NCURSES, benefiting greatly from its portability and thoroughness. Notcurses opens up advanced functionality for the interactive user on workstations, phones, laptops, and tablets, possibly at the expense of e.g. some industrial and retail terminals.

tio is a serial device tool that features a straightforward command line and configuration file interface to easily connect to serial TTY devices for basic I/O operations. To make a simpler serial device tool for working with serial TTY devices with less focus on classic terminal/modem features and more focus on the needs of embedded developers and hackers. tio was originally created as an alternative to screen for connecting to serial devices when used in combination with tmux.

A portable library and tools for archiving images of tapes with Atari 8-bit computer software. Provides a common interface for loading and saving tape images in various formats. Designed for use by emulators and Atari<->PC communication software.

FEHASHMAC is the largest collection of publicly known hash algorithms integrated into a command-line utility. FEHASHMAC contains a set of known test vectors and results for each algorithm such that the correct implementation for each hardware platform and compiler version can directly be verified. Currently 57 hash algorithms like sha1 sha224 sha256 sha384 sha512 and variants, sha3 and shake, all SHA3 finalists and blake3, md2 md4 md5 md6, rmd128 rmd160 rmd256 rmd320, whirl gost lash160 lash256 lash384 lash512 tiger2 and RFC 2104 HMAC and KMAC support are included, plus SHA3 extensions kmac128, kmac256, kmacxof128, kmacxof256 for message.

cline is a command line tool that counts code lines or non-whitespace characters in your project folder. It is designed to recursively find any source file matching specific rules and count the line breaks within that file. You may specify file suffixes to include or exclude as well as regular expressions for code lines that shall be excluded (e.g. to exclude comments). By default a heuristic algorithm skips binary files. You may configure the restrictiveness of this algorithm with command line options.

dbf is an easy-to-use command line tool to show and convert the content of dBASE III, IV, and 5.0 files. It reads dBASE databases and prints the content to the screen or converts it to comma-separated (*.csv) files which can be opened in Excel, Calc.
