Basic Linux Tasks

description
NEW CONTENT ON: http://www.FailedNormal.com Info Level: Beginner Presenter: Eli the Computer Guy Date Created: August 20, 2010 Length of Class: 53 Minutes Tracks Linux Prerequisites Installing Linux Introduction to Linux Purpose of Class This class teaches students the basic tasks that are required inorder to maintain a Linux server. Topics Covered Man Pages The importance of sudo Installing software using tasksel Installing software using apt-get Restarting services the top command Basic navigation Class Notes Sudo is used before a command. It acts like "run as administrator" in Windows Man pages are reference pages for commands and programs Example of usage: man ping q quits man pages The tasksel command installs numerous programs at one time to create a server (LAMP or such) Example: sudo tasksel Apt-get Installs, Removes or Updates Software Install: sudo apt-get install xxx Uninstall: sudo apt-get remove xxx Update: Sudo apt-get upgrade Restart Services Example: sudo /etc/init.d/xxx (restart start stop) Top is like "Task Manager" in Windows Example: sudo top K to kill a process H for help Basic navigation To change to another directory use the cd command Example: cd /etc/var/www (changes to web root folder) Linux is literal Capitalization matters!!! Final Thoughts To Logout just use the exit command Resources
