This repository provides a PowerShell profile script that enhances the command-line experience with automatic self-updating, integration with tools like Oh My Posh, zoxide, and Terminal-Icons, and extensive helper functions for file operations, process management, Git, and system tasks. The profile is designed to be modular, allowing user customization via override functions and variables without modifying the core script. It includes robust error handling, uses ShouldProcess for safe operations, and maintains a clean separation of concerns through well-defined functions. The profile script features a sophisticated update mechanism that checks for remote versions, compares file hashes to avoid unnecessary downloads, and applies updates with user confirmation. It configures PSReadLine for advanced syntax highlighting and key bindings, initializes optional modules conditionally, and provides a wide range of aliases and functions for daily productivity. The setup script automates installation of the profile and dependencies while backing up existing profiles, ensuring a safe and reproducible setup process. The code demonstrates strong engineering practices: parameter validation, proper resource disposal, conditional logic for different PowerShell editions, and thoughtful fallback mechanisms. While not exceptionally groundbreaking, it represents a well-crafted, maintainable solution that solves a common problem (shell enhancement) with attention to detail and user experience.
The kiwix-zim-updater.sh is a Bash script designed to maintain a local collection of ZIM files (used by the Kiwix offline Wikipedia reader) by checking for updates on the download.kiwix.org server. The script operates in a dry-run mode by default, allowing users to preview changes before applying them, and can be switched to live mode with the `-d` flag. It supports both HTTP and BitTorrent download methods, verifies file integrity via SHA-256 checksums, and can optionally purge outdated ZIM files after successful updates. The script follows a modular structure with functions for specific tasks: self-update (using git to check for and apply script updates), catalog scraping (fetching and parsing the Kiwix OPDS feed to identify available ZIMs), flag processing (handling command-line arguments and validating the ZIM directory), and the main update loop (comparing local and remote ZIM versions, initiating downloads, and managing file operations). Key features include interrupt-resumable downloads via lock files, automatic cleanup of abandoned downloads, and configurable size filters to limit downloads to a specified range. Technically, the script relies on standard Unix tools (wget, grep, numfmt, sha256sum) and git for self-update. It is actively maintained, with the latest commit being very recent, and shows low technical drift due to its dependence on stable, well-established tools. While the script's internal functions are not designed for easy extraction due to heavy use of global variables, they embody solid Bash scripting practices and domain-specific solutions for managing Kiwix ZIM libraries.
Termux-OS is a menu-driven shell customization tool for Termux that enables users to install and configure shells (zsh, fish, bash) with themes, fonts, and security features. The core functionality is implemented in a single bash script (os.sh) that presents an interactive menu for installing shells, applying color themes, setting up a cyber lock (password protection via SHA-256 hashing), configuring terminal behavior, and updating the script. The architecture is monolithic but modularized into functions for each major task. Key external dependencies include git, curl, pkg, and various fonts/shell frameworks. The script writes configuration files to user directories (e.g., ~/.bashrc, ~/.zshrc, ~/.termux/properties) and downloads resources from GitHub.
