- Ubuntu allows a user to accomplish tasks from either a menu-driven Graphical User Interface (GUI) or from a text-based command-line interface (CLI). In Ubuntu, the command-line-interface terminal is called Terminal, which is started:
- Menu -> File -> Open Terminal
Text inside the grey dotted box like this should be put into the command-line Terminal.
- Many changes to the operating system can only be done by a User with Administrative privileges. 'sudo' elevates a User's privileges to the Administrator level temporarily (i.e. when installing programs or making changes to the system). Example:
- 'gksudo' can be used instead of 'sudo' when opening a Graphical Application through the "Run Command" dialog box or as a menu item. Example:
gksudo gedit /etc/apt/sources.list
- Many file management tasks can be accomplished with root Administrative privileges by starting the Nautilus file manager in a similar fashion. (Use 'gksudo' if starting Nautilus from a menu item.)
- "man" command can be used to find help manual for a command. For example, "man sudo" will display the manual page for the "sudo" command:
- While "apt-get" and "aptitude" are fast ways of installing programs/packages, you can also use the Synaptic Package Manager, a GUI method for installing programs/packages. Most (but not all) programs/packages available with apt-get install will also be available from the Synaptic Package Manager. In this guide, when you see
sudo apt-get install package
you can search for package in Synaptic and install it that way.
- Many instructions use the text editor "nano" (which is universally available in Linux). However, it is often easier to use the text editor "gedit" in Ubuntu instead.
- "Menu" refers to the menu bar at the top (or bottom) of the desktop, akin to the Start menu in Microsoft Windows or the Menu bar of the Apple Macintosh.
- If you are using the 64-bit version, replace any "i386" with "amd64"
