This project is a Go shell scripting library and framework designed for writing automation scripts and CLI tools. It provides a concurrent data pipeline system for chaining sources, filters, and sinks to process text and JSON streams. The library distinguishes itself through a comprehensive toolkit for shell-like operations, including a text processing engine for regular expression filtering and frequency analysis, a filesystem utility toolkit for recursive search and path manipulation, and an integrated HTTP client wrapper for building data pipelines that fetch web content. The capability s
Captures standard output and error streams from external shell commands to redirect them into internal pipelines.
Documents standard stream redirection as a core shell feature for controlling I/O.
Este proyecto es un recurso educativo integral y una serie de tutoriales para aprender scripting en Bash y programación shell. Sirve como guía técnica y manual de referencia para escribir scripts de automatización y crear herramientas reutilizables dentro de un entorno Linux. El material se centra en la automatización de DevOps y SysOps, cubriendo el desarrollo de herramientas de línea de comandos personalizadas, automatización de administración de sistemas y la implementación de automatización de seguridad, como la generación de contraseñas aleatorias y protección contra DDoS. El alcance abarca los fundamentos del lenguaje, incluyendo variables, bucles y lógica condicional, así como capacidades operativas como monitoreo de salud del sistema, resumen de logs de servidores web y gestión remota de servidores vía SSH. También aborda la interacción con la terminal mediante la construcción de menús interactivos, formato de salida y alias de comandos. El contenido está estructurado como una serie de guías, un ebook y una referencia de scripting.
Teaches how to route command output and error messages to files or other processes using redirect operators.
CliWrap es una biblioteca de gestión de procesos asíncronos y envoltorio de procesos hijos, utilizada para ejecutar comandos externos e integrar interfaces de línea de comandos en aplicaciones. Proporciona un framework para lanzar programas externos mediante patrones asíncronos, gestionar procesos hijos y validar códigos de salida. La biblioteca destaca por su capacidad para enrutar flujos de entrada, salida y error estándar hacia buffers de memoria o flujos de eventos en tiempo real. Permite el monitoreo en tiempo real de las líneas de salida del proceso y admite la terminación de procesos mediante tokens de cancelación. El proyecto cubre una amplia gama de capacidades de gestión de procesos externos, incluyendo la configuración de variables de entorno, la redirección de flujos estándar y la captura de la salida del proceso para su uso como datos dentro de una aplicación.
Routes standard input, output, and error streams to files, buffers, or other commands.
Este proyecto es un recurso educativo integral que consiste en un tutorial de programación en Bash, una referencia de scripting y un manual de línea de comandos de Linux. Proporciona materiales instructivos para escribir scripts, automatizar tareas del sistema y dominar la navegación por terminal y la administración de sistemas Unix. Las guías cubren una amplia gama de personalización del entorno shell, incluyendo el estilo del prompt y el uso de alias. También proporciona una guía del entorno shell para gestionar archivos de configuración e inicializar entornos de usuario. Los materiales detallan un amplio conjunto de capacidades, incluyendo lógica de flujo de control, gestión de datos con arrays indexados y asociativos, y procesamiento de texto.

Implements data flow management between commands using standard pipes and file descriptor redirections.
Judge0 is an online code execution engine and multi-language compiler API designed to compile and run source code within isolated sandboxes. It functions as an asynchronous job processor that handles code submissions via a queue and provides a secure environment to run arbitrary programs while preventing unauthorized system access. The system distinguishes itself through a multi-stage compilation pipeline and a flexible execution model that supports both single-file submissions and multi-file program execution via archives. It employs an isolate-based sandboxing mechanism to enforce strict ha
Merges the standard error stream into the standard output stream for all running programs.
This project is a comprehensive command-line reference and toolkit designed for Linux system administration and network security assessment.
