SUMMER TRAINING PRESENTATIONThere's innovation in Linux. There are some really good technical features that I'm proud of. There are capabilities in Linux that aren't in other operating systems.

Linus Torvalds 1. Understand and use essential tools for handling files, directories, command-line environments, and documentation. 2. Operate running systems, including booting into different run levels, identifying processes, starting and stopping virtual machines, and controlling services. 3.

This course can be done in modular form as per the detail below Content of Training: -A famous professor Andrew Tanenbaum developed Minix ,a simplified version of UNIX that runs on PC.-Minix is for class teaching only. -No intention for commercial use In Sept 1991, Linus Torvalds , a second year student of Computer Science at the University of Helsinki, developed the preliminary kernel of Linux, known as Linux version 0.0.1 -Lineucks or nicks created primarily by Linus Torvalds in 1991. The First commercial release was in march 1992.

Beginning of Linux The Linux is mainly divided into following distributions:Fedora DebianGentooUbuntuLinux From Scratch etc.
