The document describes a trash command that provides a recycle bin functionality for Linux similar to Windows. It works by moving deleted files to the $HOME/.trash directory instead of permanently removing them. Users can restore deleted files by running the rm -l command and specifying the file row number. The trash command also checks the trash directory size and automatically deletes the oldest files if the space limit is exceeded.Pipes and filters
Pipes and filtersbhatvijetha

Pipe allows the output of one command to be used as input for another command. The "|" symbol is used to connect commands. Common examples include using "ls | more" to view a directory listing page by page or "who > userlist.txt" to redirect the output of the who command to a file. Linux treats the keyboard, terminal screen, and error messages as standard input, output, and error. Redirectors like "<" and ">" can change where input and output are directed. Commands like sort, grep, and more are examples of filters that take input, manipulate it, and produce output.Unix And Shell Scripting

This document provides an overview of the Linux file system. It describes the four types of items that can be stored in a Linux file system: ordinary files, directory files, device files, and links. It then discusses the typical directory structure, with directories like /bin, /home, and /usr. The rest of the document outlines important commands for directory and file handling, such as ls, cd, cp, and rm. It also covers making hard and soft links, specifying multiple filenames, setting file permissions, and finding/sorting files.

File is a container for storing information. It can be treated as a sequence of characters. Unlike the old DOS files, a UNIX file doesn?t contain eof (end- of ¨Cfile) mark. A file?s size is not stored in the file, nor even its name. All files attributes are kept in separate area of hard disk, not accessible to humans, but only to the kernel.ThesisScientist.com

This document provides an introduction and overview of Linux shell scripting. It discusses key topics like kernels, shells, processes, redirection, pipes, filters, variables, writing shell scripts, command line arguments, and more advanced shell scripting commands. The goal is to explain the basics of shell programming through examples of shell scripts. While it does not serve as a manual, it aims to provide more examples than typical manuals to clarify concepts for beginners.Recently uploaded (20)

Transactional Outbox & Inbox Patterns.pptxMaysam Mousa
?
This presentation provides a comprehensive overview of the Transactional Outbox Pattern and the Inbox Pattern, two essential techniques for ensuring reliable and consistent communication in distributed systems.
We start by clearly outlining the problem these patterns aim to solve¡ªnamely, maintaining data consistency between databases and message brokers in event-driven architectures. From there, we delve into what the Outbox Pattern is, how it works under the hood, and how it guarantees message delivery even in the face of failures.
The presentation then shifts focus to the Inbox Pattern, explaining its role in ensuring idempotency and preventing duplicate processing of messages. Each concept is explained with simple language, diagrams, and a logical flow that builds a solid understanding from the ground up.
Whether you¡¯re an engineer building microservices or just exploring distributed system patterns, this talk provides clarity, practical insights, and a helpful demo to see the patterns in action.
Topics Covered:
* Problem Statement
* Transactional Outbox Pattern
* How It Solves the Problem
* Internal Mechanics
* Delivery Guarantees
* Inbox Pattern Explained
* Internal Workflow
* Conclusions & Further Reading

I've been working on building a batch job framework for a few years now and blogging about it in the process. This presentation explains how and why I started building and writing about this system and the reason it changed from deploying one simple batch job to a much bigger project. I explore a number of recent data breaches, how they occurred, and what may have prevented them along the way. We consider how what make goes into an effective security architecture and well-designed security controls that avoid common pitfalls. There are friend links to many blog posts in the notes of the presentation that bypass the paywall. Topics include security architecture, IAM, encryption (KMS), networking, MFA, source control, separation of duties, supply chain attacks, and more.AI Driven Posture Analysis Fall Detection System for the Elderly.pdf

This project introduces an innovative, cost-effective solution for real-time activity monitoring of elderly individuals. By leveraging the MediaPipe pose estimation model, fuzzy logic, and finite state machines, the system can reliably track individuals, recognize static postures (standing, sitting, lying), and detect transitions, particularly focusing on falls. A key achievement is the system¡¯s zero false alarm rate, a significant advancement in vision-based fall detection systems. While the system shows promise, it faces limitations in scenarios with severe occlusions or low lighting conditions. To address these challenges, future work
will explore the use of multi-camera setups, interactive calibration modes, and audio feedback to enhance accuracy and user experience. This prototype represents a significant step towards reliable, real-time elder care. By combining advanced AI techniques with practical considerations, this system offers a scalable and effective solution to a pressing societal need.STRING FUNCTIONS IN JAVA BY N SARATH KUMAR
