This article explains how pnpm improves on npm by using OS‑level hard links and symbolic links to eliminate duplicate package copies, dramatically speed up installations, and guarantee dependency consistency, making it a superior choice for modern Node.js projects.
A blogger shared a Python script claiming to deduplicate WeChat files, but WeChat actually uses hard‑link technology to store a single copy of each file, and the script's naive name‑based deletion can cause data loss, so official guidance recommends using built‑in storage cleaning tools.
Many users think WeChat stores duplicate copies of files when forwarding, causing massive storage bloat, but the app actually uses hard links to avoid redundancy; a misguided Python script can delete files by name suffixes, risking data loss, while proper cleanup involves clearing caches, managing large chat files, disabling auto‑download, and using deep clean options.
This article introduces pnpm, compares it with npm and yarn, explains the problems of nested node_modules such as ghost dependencies and split packages, and demonstrates pnpm’s link‑based architecture, advantages, and basic command usage for efficient JavaScript project management.
This guide explains how Linux inodes identify identical files, demonstrates using ls -i, sort, and find -samefile commands, and provides a Bash script to automatically list hard‑linked duplicates, helping you reclaim disk space efficiently.
This guide explains Linux’s multi‑user permission model, how to interpret the ls -l output, the meaning of file types and permission bits, differences between symbolic and hard links, and commands for changing ownership and permissions using numeric and symbolic methods.
