Commands in Linux Operating Systems | ls cmd | pwd cmd | touch cmd | Easy Learning IT Classroom

Objectives;
• Ls command
• Pwd command
• Touch command

Commands: pwd
• Present working directory, pwd (Absolute path)
• Absolute and relative paths
• An absolute or full path points to the same location in a file system, regardless of the current working directory. To do that, it must include the root directory. By contrast, a relative path starts from some given working directory, avoiding the need to provide the full absolute path.

• Absolute Path
• /home/testuser/Desktop/helloworld.cpp
• Relative Path
• /helloworld.cpp

Commands: touch
• The touch command is the easiest way to create new, empty files. It is also used to change the timestamps (i.e., dates and times of the most recent access and modification) on existing files and directories.
• touch hello.txt
• touch -t YYMMDDHHMM fileName
• touch –t 201510290000 hello.txt

About the Site 🌐

This site provides links to random videos hosted at YouTube, with the emphasis on random. 🎥

Origins of the Idea 🌱

The original idea for this site stemmed from the need to benchmark the popularity of a video against the general population of YouTube videos. 🧠

Challenges Faced 🤔

Obtaining a large sample of videos was crucial for accurate ranking, but YouTube lacks a direct method to gather random video IDs.

Even searching for random strings on YouTube doesn't yield truly random results, complicating the process further. 🔍

Creating Truly Random Links 🛠️

The YouTube API offers additional functions enabling the discovery of more random videos. Through inventive techniques and a touch of space-time manipulation, we've achieved a process yielding nearly 100% random links to YouTube videos.

About YouTube 📺

YouTube, an American video-sharing website based in San Bruno, California, offers a diverse range of user-generated and corporate media content. 🌟

Content and Users 🎵

Users can upload, view, rate, share, and comment on videos, with content spanning video clips, music videos, live streams, and more.

While most content is uploaded by individuals, media corporations like CBS and the BBC also contribute. Unregistered users can watch videos, while registered users enjoy additional privileges such as uploading unlimited videos and adding comments.

Monetization and Impact 🤑

YouTube and creators earn revenue through Google AdSense, with most videos free to view. Premium channels and subscription services like YouTube Music and YouTube Premium offer ad-free streaming.

As of February 2017, over 400 hours of content were uploaded to YouTube every minute, with the site ranking as the second-most popular globally. By May 2019, this figure exceeded 500 hours per minute. 📈
