DB Browser for SQLite
The DB Browser for SQLite
DB Browser for SQLite (DB4S) is a high quality, visual, open source tool to create, design, and edit database files compatible with SQLite. DB4S is for users and developers who want to create, search, and edit databases. DB4S uses a familiar spreadsheet-like interface, and complicated SQL commands do not have to be learned. This program is not a visual shell for the sqlite command line tool, and does not require familiarity with SQL commands. It is a tool to be used by both developers and end users, and must remain as simple to use as possible in order to achieve these goals. Import and export records as text, import and export tables from/to CSV files, import and export databases from/to SQL dump files, issue SQL queries and inspect the results, examine a log of all SQL commands issued by the application, plot simple graphs based on table or query data. -

pdfsandwich generates "sandwich" OCR pdf files, i.e. pdf files which contain only images (but no editable text) will be processed by optical character recognition (OCR) and the text will be added to each page invisibly "behind" the images. pdfsandwich is a command line tool which is supposed to be useful to OCR scanned books or journals. It is able to recognize the page layout even for multicolumn text. Essentially, pdfsandwich is a wrapper script which calls the following binaries: convert, unpaper, tesseract, gs, and hocr2pdf (if tesseract < 3.03). It is known to run on Unix systems and has been tested on Linux and MacOS X. It supports parallel processing on multiprocessor systems. In contrast to most competing sandwich programs, it performs preprocessing of the scanned images, such as de-skewing or removal of dark edges etc. For further information please read the manual: http://www.tobias-elze.de/pdfsandwich/index.html

AI Commits
A CLI that writes your git commit messages for you with AI
AI Commits is a command-line tool that writes your git commit messages for you using an AI model. It works by running git diff to gather your staged code changes, sending that diff to an LLM (originally GPT-3, now configurable), and receiving back a concise, human-readable commit message. The tool is designed to integrate cleanly into a developer’s workflow so that generating a descriptive commit message becomes a single command rather than a chore. It supports configuration via environment variables or config files so you can set your API key, preferred model, message style, and more. There are also options to preview, edit, or regenerate the AI-proposed message before actually committing, giving developers control instead of blindly trusting the output. Because it’s published as an npm package and even as a Homebrew formula, installation is straightforward across platforms. -

testssl.sh
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. -

aws-cli
Universal Command Line Interface for Amazon Web Services
The AWS CLI is the universal command-line interface for managing AWS services, automating tasks, and scripting cloud workflows. It exposes nearly every public API from EC2 and S3 to IAM, Lambda, and beyond, providing parity with the service SDKs in a tool you can run anywhere. Profiles, regions, single-sign-on, and credential helpers make it straightforward to switch contexts securely across accounts and environments. Its output controls and JMESPath querying let you slice, filter, and transform JSON responses directly in the shell, which is essential for automation. Waiters, paginators, and retries handle long-running or large list operations cleanly so scripts are resilient. The CLI’s stability and extensive documentation make it a cornerstone for CI/CD, incident response, and day-to-day operations. -

jdbc2csv.jar
Command-line sql JDBC tool
jdbc2csv is a small command-line tool written in JAVA and can be used on all platforms, for which JRE 8 or higher is available. To connect to a specific DBMS the tool uses its JDBC driver. The result of the executed 'select' query is displayed in CSV format ( different standards are supported ). When there is an error the tool stops with exit code 1 and the error message is output on stderr. jdbc2csv is created with a main purpose to be used in shell-scripts. Relatively easy to configurate, this tool is suitable for queries ‘select’, ‘update’ and ‘delete’. I think that is not suitable for a large number of requests, like 'insert'. -

bat
Go implement CLI, cURL-like tool for humans
bat is a Go-implemented, cURL-like command-line HTTP client designed to be “for humans,” emphasizing an expressive and intuitive syntax. It allows developers to test, debug, and generally interact with HTTP servers using concise commands that feel more like a small DSL than raw cURL flags. The tool supports a wide range of HTTP operations including custom methods, headers, JSON payloads, form submissions, file uploads, authentication and proxy configuration. Its README showcases simple “hello world” usage as well as more advanced scenarios, such as inspecting the exact request being sent via print options. Because it is written in Go and distributed as a single binary, it is easy to install and use across platforms, and it can even be run inside Docker containers for isolated workflows. The project is inspired by HTTPie but tailored to Go’s strengths, with an Apache-2.0 license that encourages both personal and commercial use. -

Gitlab CLI
Ruby wrapper and CLI for the GitLab REST API
Gitlab CLI is a Ruby gem and CLI tool that wraps the REST API of GitLab (including self-hosted GitLab instances) to make automation, scripting and integration simpler. It provides a Ruby DSL that abstracts away direct HTTP calls, letting developers interact with GitLab’s API in idiomatic Ruby (creating projects, merge requests, listing users, etc.). In addition to the Ruby library, there is a command-line interface which enables many GitLab operations from the terminal (or scripts) without needing to manually craft API requests. The gem supports customization of endpoint URL, private tokens, proxy and HTTP options, making it suitable for self-managed GitLab instances as well as gitlab.com. It is test-covered and built to be simple to integrate into Ruby projects or CI scripts. Being open-source under a BSD-2-Clause license, it invites reuse in organizational tooling or internal DevOps workflows. Overall, it is a useful tool for teams working with GitLab who want to automate tasks. -

The Art of Command Line
Master the command line, in one page
The Art of Command Line is a single, highly curated page of tips that distills years of Unix command-line experience into practical, memorable guidance. It emphasizes fluency: small habits and commands that compound into faster debugging, data wrangling, and system navigation. The content spans basic shell usage, text processing with tools like grep/sed/awk, networking and performance inspection, and advice for working safely with root and destructive commands. Many entries highlight lesser-known flags or idioms that save keystrokes or avoid pitfalls, and the list aims to be dense but scannable. It is written for Linux first while acknowledging macOS and Windows differences where relevant. The document is also available in multiple languages, reflecting broad community interest and contributions. -
