PVE-Tools is a comprehensive, interactive Bash administration toolkit for Proxmox VE 9.x (Debian 13 Trixie). It provides a menu-driven CLI that wraps native PVE commands (qm, pct, pvesm, etc.) to automate common hypervisor management tasks: system optimization, APT mirror switching, kernel/GRUB management, GPU passthrough (NVIDIA, AMD, Intel SR-IOV/GVT-g), VM/container backup/restore/clone/migration, host networking (bridge, bond, VLAN, IPv6, firewall), storage (Ceph, LVM, mount), security auditing and CVE mitigation, and third-party tool integration (FastPVE, CoolerControl, IT87 drivers). The tool is distributed as a single assembled script built from modular source files (lib/ + src/modules/) via build.sh, and can be installed as a system command or run directly. It features a two-tier confirmation system for high-risk actions, marker-based config block management for idempotent edits, and automatic backups under /var/backups/pve-tools/. The UI is primarily Chinese with a branded ASCII banner and community channels built in.
The repository hosts 'The Secret Bit', a static website serving as a guide to Linux commands and concepts, primarily in Persian/Farsi. Built with Hugo, it features automated content generation from GitHub issues via the rain.py script, RTL/LTR language support, dark/light theme toggling, client-side search, and offline capabilities through a service worker. The site is organized into 'Tools' (specific commands) and 'Fundamentals' (concepts) sections, with contributions managed through labeled GitHub issues.
testssl.sh is a mature, command-line Bash tool for comprehensive TLS/SSL security auditing of network services. It tests cipher support, protocol versions (SSLv2 through TLS 1.3), cryptographic vulnerabilities (Heartbleed, CCS, ROBOT, BEAST, POODLE, LOGJAM, FREAK, and many others), certificate validation, HTTP security headers, and STARTTLS on a wide range of protocols. The tool works by performing socket-level TLS handshakes and comparing results against embedded data files. It also includes a client simulation feature that replays ClientHellos from over 100 real-world browsers and libraries to detect server behavior differences. The architecture is a single large Bash script (testssl.sh) with supporting data files under etc/ and utility scripts in utils/. It is driven by command-line options and environment variables, producing output in terminal color, JSON, CSV, HTML, and log formats. The project has active maintenance with a thorough test suite and CI pipelines, though some data sources (e.g., SSL Labs API) are deprecated, and the client simulation data requires manual updates.
This is a single-file Bash script that performs a comprehensive security and performance audit of a Linux VPS. It checks SSH configuration, firewall status, intrusion prevention systems (Fail2ban/CrowdSec), failed login attempts, system updates, running services, open ports, disk/memory/CPU usage, sudo logging, password policy, and SUID files. The script outputs color-coded PASS/WARN/FAIL results to the console and writes a detailed timestamped report to a file. It is designed for Ubuntu/Debian-based systems and requires root or sudo privileges. The architecture is a monolithic Bash script with no external dependencies beyond standard Linux utilities and optional tools like UFW, Fail2ban, and Docker. The code is well-structured with configurable thresholds and file paths, demonstrating solid Bash scripting practices. However, it is not designed for reuse as a library; it is a standalone tool.
ttab is a single-file Bash CLI that programmatically opens new terminal tabs and windows on macOS (Terminal.app and iTerm2) and Linux (gnome-terminal). It supports running startup commands in the new tab, setting working directory, title, and profile, creating iTerm2 horizontal/vertical splits (-v/-h), creating tabs without stealing focus (-g/-G), delaying command submission (-l), and clearing the screen (-q). The entire application is bin/ttab: a ~700-line Bash script with zero runtime dependencies that parses options via getopts, detects the calling terminal through TERM_PROGRAM / GNOME_TERMINAL_SCREEN or an explicit -a flag, synthesizes backend-specific automation (AppleScript for Terminal.app and iTerm2, with distinct v2/v3 syntax paths, and a CLI argument string for gnome-terminal), and executes it via 'exec osascript' on macOS or eval on Linux. It embeds its full Markdown man page as a here-doc extracted by sed, so --help, --man, and --man-source all work from the single distributed file.
Bash-my-AWS is a CLI toolset designed to manage AWS resources using Bash functions and aliases. It wraps the AWS CLI with convenience functions for listing, filtering, and manipulating resources like EC2, S3, and CloudFormation. The architecture is a monolithic Bash library sourced into the user's shell environment, with modularized logic in `lib/*-functions`. It relies heavily on `awscli`, `jq`, and standard Unix utilities. The tool implements a pipe-skimming pattern (`skim-stdin`) that allows chaining commands (e.g., `instances | instance-stop`), enhancing usability for shell scripting. It includes a Python-based caching proxy (`bin/cachews`) to reduce API latency. While well-structured for Bash, it carries inherent risks due to the language's limitations, including security vulnerabilities in SSH handling and reliance on `eval` for argument inference. The repository is actively maintained with recent commits and a comprehensive test suite using a custom BDD-style framework. However, technical drift is moderate due to the rapid evolution of AWS APIs and Bash-specific security concerns. The codebase is suitable for engineers comfortable with Bash scripting who need a robust set of AWS management utilities.
git-log-tree is a single-file Bash CLI tool that renders a fancy, colored git log graph in the terminal. It wraps `git log` with `--topo-order`, `--parents`, and a custom pretty format, then parses the output to draw a tree using Unicode box-drawing characters and ANSI colors. The script handles complex branching, merges, and orphan commits, assigning colors to branches with an algorithm that minimizes reuse and ensures contrast. It respects the `NO_COLOR` environment variable and auto-detects color support. The tool pipes output through `less -F -R -S -X` for paging. The repository includes a comprehensive BATS test that creates a synthetic git history via fast-import and verifies the exact rendered output, along with a GitHub Actions workflow for coverage via kcov. The code is well-structured for a Bash script, using associative arrays and bit manipulation for efficient color sorting, but is monolithic with global state, limiting component reusability.
This repository provides an Emacs package that implements bash completion within Emacs shell buffers and command prompts. It works by spawning or reusing a bash process to generate completions via `compgen`, respecting the user's bash configuration including aliases, functions, and programmable completion. The package handles edge cases like quoted strings, redirections, and colon-separated variables, and works with TRAMP for remote shells. The architecture is centered around a single Emacs Lisp file that defines functions for parsing shell commands, communicating with bash processes, and formatting completion results. Key entry points include `bash-completion-setup` for initialization and `bash-completion-dynamic-complete` for integration with Emacs' completion system.
Minecraft Server Control Script (MSCS) is a monolithic Bash/Perl CLI tool for managing multiple Minecraft server instances on Linux. It provides a comprehensive set of actions: starting/stopping/restarting worlds, creating/deleting/enabling/disabling worlds, backing up (via rdiff-backup), mapping (via Minecraft Overviewer), updating server software, sending commands, and querying server status. The architecture is a single large shell script (msctl) with a wrapper (mscs) for system integration. Configuration is done via INI-style defaults files and per-world properties. The script relies on external tools: Java, Perl, Python, wget, rdiff-backup, rsync, socat, and flock. It integrates with systemd via provided service files and supports LSB init scripts. The codebase is functional and well-documented internally, but tightly coupled and monolithic, making extraction of individual components non-trivial.
This repository is a curated collection of Git hook examples, organized by hook type (pre-commit, commit-msg, pre-push, etc.). Each hook type directory contains a README explaining the hook's purpose and one or more example shell scripts that demonstrate how to implement the hook for common tasks such as linting, branch protection, and commit message validation. The repository does not contain a runnable application but serves as a reference for developers looking to implement Git hooks in their projects. The example scripts are self-contained, written in POSIX shell or Bash, and rely only on standard Unix tools and Git commands, making them easy to adapt to various projects. While the hooks are simple, they illustrate practical patterns for enforcing code quality, preventing dangerous operations, and integrating with issue trackers. The repository is maintained with occasional updates, and the examples are relevant to current Git usage. The scripts are designed to be copied directly into a project's .git/hooks directory with minimal modification, often requiring only customization of variables like branch names or regex patterns.
Pokemon-Terminal is a CLI tool that sets Pokemon images as terminal backgrounds or desktop wallpapers. It supports multiple terminal emulators (iTerm2, ConEmu, Terminology, Tilix, Windows Terminal, Kitty) and desktop environments (macOS, GNOME, sway, feh, swww, Windows) via a clean adapter pattern with runtime discovery. The system parses user-supplied filters (name, region, type, brightness) from a database of 719 Pokemon plus custom extras, then applies the selected image to the terminal or wallpaper. It also features a slideshow mode using multiprocessing and platform-specific named events for IPC. While the codebase has some rough edges (global mutable state in filters, a hacky unittest.mock.patch in production for POSIX named event detection), the overall architecture is well-modularized and demonstrates solid use of abstraction and reflection. The repo is actively maintained with recent commits and a large community (4.8k stars).
ffs is a FUSE-based filesystem that mounts semi-structured data formats (JSON, TOML, YAML) as a Unix directory tree, enabling interactive editing with standard shell commands (cat, echo, mv, rm, mkdir). It includes companion tools pack (directory tree → data format) and unpack (data format → directory tree). The system is implemented in Rust with a modular architecture: the nodelike crate provides a generic trait and Node enum for format-agnostic representation, while ffs handles FUSE mount logic and pack/unpack handle batch conversion. Key features include lazy/eager loading strategies, name munging for special characters, extended attribute support, and format conversion (e.g., JSON to YAML). The repository also contains an extensive benchmark suite using real-world datasets (FDA, GitHub, NOAA, etc.) to compare loading strategies. While the core functionality is complete and well-tested with over 60 integration test scripts, the project appears to be in a stale maintenance state with no recent commits (last significant activity in 2021) and several open issues. The codebase demonstrates good software engineering practices (modular design, comprehensive tests, performance instrumentation) but has limited reuse potential beyond its specific domain of semi-structured data manipulation via filesystem semantics.
Vrecord is a bash-based CLI and GUI application for capturing analog and digital video signals to digital files, designed primarily for audiovisual archivists. It wraps ffmpeg-ma (a MediaArea fork of FFmpeg with Blackmagic DeckLink support) to capture from DeckLink devices, DV via FireWire, or audio-only inputs, and provides real-time monitoring through ffplay or mpv with configurable scopes (waveform, vectorscope, histograms, bit planes, etc.). The application generates preservation-oriented sidecar files including frame-level MD5 checksums, SCC closed caption files, QCTools XML reports, timecode logs, and optional access MP4 copies. Post-capture, it runs MediaConch policy checks, generates benchmark graphs with gnuplot, and can embed logs into Matroska containers. The codebase is monolithic, consisting of a single ~5000-line bash script (vrecord) that handles configuration (via gtkdialog), capture pipeline construction, and post-processing. Companion scripts include vtest for test signal output, vplay for playback with QC overlays, and cchex_to_display for real-time closed caption display. Dependencies are managed via Homebrew on macOS and Linux (including the AMIA Open Source tap). The project has been maintained for nearly a decade and is actively developed by a community of archivists and developers.
Mac CLI is a monolithic shell script application that provides a unified command-line interface for managing macOS systems. It implements a plugin architecture where each functionality area (DNS, SSH, Git, etc.) is implemented as a separate shell script sourced by the main 'mac' executable. The tool automates common developer tasks by wrapping native macOS commands and utilities like softwareupdate, brew, osascript, and various network tools. While functional, the codebase shows signs of age with inconsistent parameter handling, some bugs (like variable name mismatches in SSH plugin), and reliance on outdated patterns for command dispatching.
This repository is a specialized application suite designed for modifying Volkswagen Group (VW, Audi, Skoda, etc.) MIB (Modular Infotainment Architecture) infotainment head units. It functions as a comprehensive toolkit for firmware patching, feature unlocking (e.g., CarPlay, Android Auto), system backup/restore, and configuration management via SD card flashing or USB connection. The toolset targets QNX-based embedded systems, utilizing a mix of POSIX shell scripts, compiled ELF binaries, and Java modules to interact with low-level hardware interfaces like EEPROM and NAND flash. Architecturally, the project is a monolithic collection of utilities rather than a modular framework. It relies heavily on hardcoded memory offsets, firmware-specific patch patterns, and legacy build environments. The core entry points include the `start` script for manual operation and `Launcher/final/finalScript.sh` for automated SD updates. Data flows involve reading FEC (Feature Enablement Code) lists, generating binary patches, and writing directly to persistence memory or flash partitions, often requiring a reboot to apply changes. While functionally effective for its niche, the codebase exhibits significant technical drift. Compiled binaries are built with GCC 4.4.2 (circa 2010) and link against 2012-era OpenSSL and QNX libraries. Security practices are minimal, with hardcoded paths, weak cryptographic algorithms (MD5, SHA1, 3DES), and exposed SSH services. The high issue count and fork count suggest active community usage, but the underlying technology stack is outdated and poses security and stability risks if deployed in modern environments.
A Debian-packaged Bash toolset that ports ParrotSec's anonsurf and pandora tools to Kali Linux. The anonsurf component makes the whole system use a Tor transparent proxy: it saves existing iptables rules, flushes them, redirects DNS to a local Tor DNSPort, forwards TCP/UDP/ICMP through Tor's TransPort on port 9040, excludes private and local networks, disables IPv6 through sysctl, and supports changing Tor identity. The pandora component is a shutdown service that drops kernel caches and scrubs RAM with sdmem from secure-delete. The repository is not a library or service; it is an installer plus a .deb source tree, with GitHub Actions that build the package and verify it installs in Kali rolling containers. The code is functional and has some good operational detail, including UID-based iptables owner rules, resolvconf vs. plain resolv.conf handling, and package maintainer scripts that swap torrc files. It is also rough around the edges: it is largely monolithic shell, has no unit tests for the iptables logic, relies on outdated actions/checkout@v2 CI actions, and the IPv6 re-enable function has a filename typo that checks /etc/sysctl.d/98-kali-anonsurf but removes /etc/sysctl.d/98-kali-anonsurf.conf, which can prevent IPv6 from being re-enabled after stop.
This repository is a research artifact from the NL2Bash project (LREC 2018), providing a dataset and neural semantic parser for translating natural language descriptions into Bash one-liners. The core contributions include a parallel corpus of ~10k NL–Bash pairs, TensorFlow-based sequence-to-sequence models with attention and copy mechanisms, a custom Bash command parser (bashlint) that normalizes commands using a grammar extracted from man pages, and evaluation tools including tree edit distance and manual judgment pipelines. The codebase is primarily a research prototype with pre-trained model checkpoints, data preprocessing scripts, and evaluation files. While the dataset and parser are valuable, the dependency on TensorFlow 1.x, JavaCC, and Python 2/3 compatibility indicates significant drift. The repository is no longer actively maintained, but the documented methodology and reusable components (e.g., tree edit distance, statistical spell checker) remain relevant for similar NL-to-code tasks.
This is a personal dotfiles repository by Dave Eddy (bahamas10). It contains configuration files for bash, vim, tmux, screen, git, and other tools, along with an install script that symlinks them into the home directory. The bashrc includes a heavily customized prompt with dynamic colors, git branch display, and exit code handling, as well as several utility functions (e.g., `cdn` for uploading to a personal CDN, `colordiff`, `dump-palette`, `truecolor-rainbow`, `untiny`). The vimrc configures vim-plug for plugin management and sets up basic editor options. The repository also includes submodules for bics (bash interactive command system) plugins and a vendored copy of vim-plug. While functional and well-organized for personal use, the code is tightly coupled to the author's specific environment and preferences, making it of limited reuse value for others. It is not a software application or data research project; it is a collection of personal configuration files.
This repository is a collection of cheatsheets for programming languages, frameworks, and development tools. It is not a software application, data pipeline, or research project. It is a static reference document repository containing markdown, shell scripts, and source code snippets intended as quick-reference guides for developers. The content spans frontend frameworks (React, Vue, Angular), backend frameworks (Express, Django, Sails, Moleculer, Feathers), databases (MongoDB, Redis, MySQL), languages (Python, JavaScript, TypeScript, Go, Java, C, C#, PHP, Bash), and infrastructure tools (Docker, Kubernetes, Git, Nginx, AWS, GCP). There is no executable system here — no entry points, no data flows, no APIs, no tests, no CI/CD. It is purely informational content. The repository has 46K+ stars and 6.7K forks, indicating high community value as a reference resource. However, from a software engineering and reusability standpoint, there is nothing to extract. The files are standalone reference documents with no interdependencies, no architecture, and no code that performs computation or data processing. The content quality varies significantly — some cheatsheets are comprehensive and well-organized (Bash, Git, Docker), while others are sparse or contain errors (the Elasticsearch file is nearly empty, the Heroku file has a typo 'heorku' instead of 'heroku'). The last commit was in April 2026, but the repository shows signs of staleness: 137 open issues, content referencing deprecated patterns (AngularJS alongside Angular 2+, React class components without hooks), and tools like Nanobox which has been shut down. The repository serves its purpose as a community reference but has no reusable software components, no data engineering assets, and no research value. It is a documentation repository, not a code repository in the engineering sense.
