signal-cli
signal-cli provides a commandline, dbus and JSON-RPC interface
signal-cli is a command line interface for the Signal messenger. It supports registering, verifying, sending and receiving messages. signal-cli uses a patched libsignal-service-java, extracted from the Signal-Android source code. For registering you need a phone number where you can receive SMS or incoming calls. signal-cli is primarily intended to be used on servers to notify admins of important events. For this use-case, it has a daemon mode with D-BUS interface (man page) and JSON-RPC interface (documentation). For the JSON-RPC interface, there's also a simple example client, written in Rust. -

Testing TLS/SSL encryption anywhere on any port
testssl.sh is a free command-line tool that checks a server's service on any port for the support of TLS/SSL ciphers, protocols as well as recent cryptographic flaws and more. testssl.sh is free and open-source software. You can use it under the terms of GPLv2, please review the License before using it. Works for Linux, Mac OSX, FreeBSD, NetBSD and WSL/MSYS2/Cygwin out of the box, no need to install or configure something, no gems, CPAN, pip or the like. OpenBSD only needs bash to be postinstalled. You can test any SSL/TLS enabled and STARTTLS service, not only webservers at port 443. Several command line options help you to run your test and configure your output. If a particular check cannot be performed because of a missing capability on your client side, you'll get a warning. You can look at the code, see what's going on and you can change it. -

arduino-cli
Arduino command line tool
Arduino CLI is an all-in-one solution that provides Boards/Library Managers, sketch builders, board detection, uploader, and many other tools needed to use any Arduino compatible board and platform from the command line or machine interfaces. In addition to being a standalone tool, Arduino CLI is the heart of all official Arduino development software (Arduino IDE, Arduino Web Editor). The script requires sh, which is always available on Linux and macOS. sh is not available by default on Windows, though it is available as part of Git for Windows (Git Bash). If you don't have sh available, use the "Download" installation option. If you would like to use the arduino-cli command from any location, install Arduino CLI to a directory already in your PATH or add the Arduino CLI installation path to your PATH environment variable. -

AIClient-2-API
Simulates Gemini CLI, Antigravity, Qwen Code, and Kiro client
AIClient-2-API is a developer-focused tool that acts as a compatibility layer, simulating multiple AI client interfaces and translating them into standardized API requests compatible with OpenAI-style endpoints. It enables developers to connect various AI tools and clients, such as Gemini CLI, Qwen Code, or other proprietary interfaces, into a unified backend without needing to rewrite integrations. The system is designed to support high-throughput usage, handling large volumes of requests while maintaining compatibility across different AI ecosystems. It also provides access to alternative models, including built-in support for certain Claude-based functionalities, expanding flexibility for developers working with multiple providers. By abstracting away client-specific differences, it simplifies AI application development and reduces integration overhead. -

Percona Toolkit
A collection of advanced open source command-line tools
Percona Toolkit is a collection of battle-tested command-line tools for MySQL and MariaDB that help diagnose performance, verify integrity, and perform online maintenance safely. Utilities such as pt-query-digest analyze slow logs and packet captures to surface hotspots and regressions, while pt-online-schema-change applies ALTERs with minimal blocking by copying and swapping tables. Consistency tools like pt-table-checksum and pt-table-sync detect and reconcile replication drift across replicas or shards. Other helpers find duplicate indexes, unused keys, skewed data distributions, and configuration issues that quietly erode performance. Each tool favors guardrails: dry runs, throttling, and resumable operations reduce the risk of harming production workloads. Operators and DBAs rely on the toolkit to bring observability and predictability to busy database fleets without hand-rolled scripts. -

cloudflare-speed-cli
CLI for internet speed test via cloudflare
cloudflare-speed-cli is a Rust-based command-line internet speed testing tool that interfaces with Cloudflare’s public speed test endpoints, letting users measure download and upload throughput, latency, and more from a terminal. It presents results in an interactive text-user-interface (TUI) that charts real-time metrics as tests run, making it easy to visually inspect performance trends without leaving the console. The tool also stores historical test results and can export measured data as structured JSON for scripting, logging, or integration with automation tools. Users can bind tests to specific network interfaces or source IPs, making it flexible for complex networking environments or servers with multiple network paths. In addition to TUI mode, it supports headless text or JSON output for pipelines and monitoring systems. -

Live CD With Zerofree Utility i686 32Bit
A Custom Puppy Linux Live CD With Zerofree Utility i686 32 Bit
After Booting with this Live CD, just click on the CDROM icon on the Desktop, to open its folder contents, then Right Click the zerofree.sh file and Choose the "Run in Terminal" option and then follow the instructions shown on the terminal. As you may be aware, Booting with a Live CD, requires that you need to change the Boot Order on your System / Guest BIOS, quickly on startup, by pressing either F2 OR F12 OR F10 OR an equivalent key and then change the Boot Order to boot from the CDROM first. Some Hints: Puppy Linux Live CDs show some dialogs / settings window on first startup / first shutdown. Feel free to dismiss / close them, if you do not want to make any changes, to the live cd's operation, next time, on the same system. This will not affect the zerofree's work in any way. Apart from this, using the Internet Browser, built in, would require a Free Memory of 1 GB or more, for better Performance ( as it is generally a memory intensive activity ) -

Filemaker Data Migration Tool Automator
Simplifies the use of the Filemaker Data Migration Tool
The Data Migration Tool Automator is tool for simplifying the use of the Filemaker Data Migration Tool (FDMT) . The FDMT is a command line tool published by Filemaker that facilitates the migration of data from an existing production database to a new clone version of the same database. The problem with the FDMT is that it is a command line tool which requires long and complicated instructions to execute. It can take several attempts and a lot of time to get the exact instruction you need. The Filemaker Data Migration Tool Automator is a Filemaker database which makes it easy to create the command line syntax and calls the terminal scripts for the Filemaker Data Migration Tool. It simplifies the selection of the migration files, enter usernames and passwords and directs them to the FDM For more information and download links refer to: https://community.claris.com/en/s/article/FileMaker-data-migration-tool -
