How to Start Again on Terminal

Whether you're a new Linux user or yous've been using Linux for a while, we'll help yous get started with the terminal. The terminal isn't something you lot should exist scared of — it'south a powerful tool with lots of uses.

Y'all tin can't acquire everything you demand to know nearly the terminal past reading a unmarried commodity. It takes experience playing with the concluding firsthand. We hope this introduction helps you get to grips with the basics so you can keep learning more.

Basic Terminal Usage

Launch a terminal from your desktop's application carte and you will see the bash shell. There are other shells, but most Linux distributions use bash by default.

You tin launch a program by typing its name at the prompt. Everything you launch here — from graphical applications similar Firefox to control-line utilities — is a plan. (Bash actually has a few built-in commands for bones file direction and such, only those function similar programs, too.) Unlike on Windows, you don't have to blazon the full path to a program to launch it. For instance, allow'due south say you wanted to open Firefox. On Windows, yous'd need to type the total path to Firefox's .exe file. On Linux, you tin but blazon:

firefox

Press Enter afterwards typing a command to run it. Note that you don't need to add an .exe or anything similar that — programs don't have file extensions on Linux.

Terminal commands tin also accept arguments. The types of arguments you lot tin can utilize depends on the program. For example, Firefox accepts web addresses as arguments. To launch Firefox and open How-to Geek, y'all could run the post-obit control:

firefox howtogeek.com

Other commands yous would run in the terminal part only like Firefox, except many run merely in the terminal and don't open up any sort of graphical awarding window.

Installing Software

One of the most efficient things to do from the concluding is install software. Software management applications like the Ubuntu Software Center are fancy frontends to the few concluding commands they use in the background. Instead of clicking around and selecting applications one-by-one, you tin can install them with a terminal command. You fifty-fifty even install multiple applications with a single command.

On Ubuntu (other distributions have their own packet direction systems), the command to install a new software bundle is:

sudo apt-go install packagename

This may seem a bit complicated, but it'south working just like the Firefox command higher up. The to a higher place line launches sudo, which asks for your password before launching apt-become with root (ambassador) privileges. The apt-get plan reads the arguments install packagename and installs a packet named packagename.

Nonetheless, you can too specify multiple packages as arguments. For instance, to install the Chromium web browser and Pidgin instant messenger, you could execute this command:

sudo apt-get install chromium-browser pidgin

If you simply installed Ubuntu and wanted to install all your favorite software, yous could exercise information technology with a single command like the above one. You would just need to know the package names of your favorite programs, and you lot tin can guess them adequately easily. You can also refine your guesses with the assist of the tab completion play a joke on below.

Working With Directories and Files

The shell looks in the current directory unless yous specify some other directory. For instance, nano is an piece of cake-to-use final text editor. The command nano document1 tells nano to launch and open the file named document1 from the current directory. If you wanted to open a document located in another directory, you'd need to specify the full path to the file — for example, nano /home/chris/Documents/document1 .

If you specify a path to a file that does not exist, nano (and many other programs) will create a new, blank file at that location and open it.

To work with files and directories, y'all will need to know a few bones commands:

• cd — That ~ to the left of the prompt represents your dwelling house directory (that'due south /home/you), which is the final's default directory. To alter to some other directory, you tin utilise the cd command. For example cd / would change to the root directory, cd Downloads would change to the Downloads directory within the current directory (and so this but opens your Downloads directory if the terminal is in your home directory), cd /home/yous/Downloads would alter to your Downloads directory from anywhere in the organisation, cd ~ would modify to your home directory, and cd .. would get up a directory.
• ls — The ls command lists the files in the current directory.

• mkdir — The mkdir command makes a new directory. mkdir example would create a new directory named case in the current directory, while mkdir /dwelling house/you lot/Downloads/test would create a new directory named test in your Downloads directory.
• rm — The rm command removes a file. For instance, rm case removes the file named example in the current directory and rm /dwelling house/you lot/Downloads/example removes the file named case in the Downloads directory.
• cp — The cp command copies a file from 1 location to another. For instance, cp example /abode/yous/Downloads copies the file named example in the current directory to /home/y'all/Downloads.
• mv — The mv control moves a file from one location to another. It works exactly like the cp command higher up, but moves the file instead of creating a copy. mv tin also be used to rename files. For case, mv original renamed moves a file named original in the electric current directory to a file named renamed in the current directory, effectively renaming it.

This may be a bit overwhelming at beginning, simply these are the basic commands you lot need to master to effectively work with files in the concluding. Move around your file system with cd, view files in the current directory with ls, create directories with mkdir, and manage files with the rm, cp, and mv commands.

Tab Completion

Tab completion is a very useful trick. While typing something — a command, file name, or some other types of arguments — you lot can press Tab to autocomplete what y'all're typing. For example, if you lot type firef at the terminal and printing Tab, firefox automatically appears. This saves you from having to blazon things exactly — yous can press Tab and the shell volition finish typing for you. This besides works with folders, file names, and package names. For example, you can type sudo apt-get install pidg and printing Tab to automatically complete pidgin.

In many cases, the beat won't know what yous're trying to type considering at that place are multiple matches. Press the Tab key a 2nd time and you'll see a list of possible matches. Keep typing a few more letters to narrow things down and printing Tab again to continue.
