Other versions of Linux, or other flavours of Ubuntu, will usually have a terminal launcher located in the same place as your other application launchers.Often referred to as the shell, terminal, console, prompt or various other names, it can give the appearance of being complex and confusing to use.Yet the ability to copy and paste commands from a website, combined with the power and flexibility the command line offers, means that using it may be essential when trying to follow instructions online, including many on this very website This tutorial will teach you a little of the history of the command line, then walk you through some practical excercises to become familiar with a few basic commands and concepts.Well assume no prior knowledge, but by the end we hope youll feel a bit more comfortable the next time youre faced with some instructions that begin Open a terminal.
This tutorial includes some specfic steps for Ubuntu 18.04 but most of the content should work regardless of your Linux distribution. ![]() These terminals were pretty basic by modern standards: just a keyboard and screen, with no power to run programs locally. Instead they would just send keystrokes to the server and display any data they received on the screen. There was no mouse, no fancy graphics, not even any choice of colour. Obviously, therefore, any programs that ran on the mainframe had to produce text as an output and accept text as an input. Even on machines from the 1970s, running hundreds of terminals across glacially slow network connections (by todays standards), users were still able to interact with programs quickly and efficiently. The commands were also kept very terse to reduce the number of keystrokes needed, speeding up peoples use of the terminal even more. This speed and efficiency is one reason why this text interface is still widely used today. ![]() Whether creating files, renaming them, putting them into subdirectories or moving them around on disk, users in the 70s could do everything entirely with a textual interface. Each of these tasks required its own program or command: one to change directories ( cd ), another to list their contents ( ls ), a third to rename or move files ( mv ), and so on. In order to coordinate the execution of each of these programs, the user would connect to one single master program that could then be used to launch any of the others. By wrapping the users commands this shell program, as it was known, could provide common capabilities to any of them, such as the ability to pass data from one command straight into another, or to use special wildcard characters to work with lots of similarly named files at once. Open Command Line Ubuntu Series Of ShellUsers could even write simple code (called shell scripts) which could be used to automate long series of shell commands in order to make complex tasks easier. The original Unix shell program was just called sh, but it has been extended and superceded over the years, so on a modern Linux system youre most likely to be using a shell called bash. Dont worry too much about which shell you have, all the content in this tutorial will work on just about all of them. The core part of Linux is designed to behave similarly to a Unix system, such that most of the old shells and other text-based programs run on it quite happily. In theory you could even hook up one of those old 1970s terminals to a modern Linux box, and access the shell through that. But these days its far more common to use a software terminal: that same old Unix-style text interface, but running in a window alongside your graphical programs. Lets see how you can do that yourself. Yes, the developers have set up the launcher with all the most common synonyms, so you should have no problems finding it.
