# Command Line Shell, for *Absolute* Beginners
# Command Line Shell, for _Absolute_ Beginners
So, you want to join a public-access shell community like tilde.team, but you don't yet have experience using GNU+Linux or other UNIX-like operating systems? This tutorial is designed to give you enough guidance that you can get started and move on to successfully directing your future learning. Once you get a basic level of self-sufficiency, tilde.team is a great place to practice and learn more.

## GNU+Linux is a text-based operating system. And it takes work and thought to start using.
You'll find a lot of people online arguing that GNU+Linux is _not_ a text-based operating system, and that it in fact has a GUI interface just like Windows. It is true that you can use GNU+Linux through a graphical user interface (GUI) like Gnome, or that you can use services from GNU+Linux servers like tilde.team through a web interface. But the people who are so keen on GUIs are saying this to make GNU+Linux sound like an easy transition for Windows or Mac users. However: (1) to really leverage the power of GNU+Linux, you need to learn to interact with it as a text-based system, and (2) while it is different, it's not really that hard. It will take effort to learn the differences, but that effort will pay huge dividends.

## How do I connect to a shell server?
The most common way to connect remote GNU+Linux system is with an SSH client. SSH stands for secure-shell. SSH allows you to make a private connection between your computer and a shell server like [tilde.team](https://tilde.team), and it ensures that nobody else along the wire can listen in on your connection. Check out [our SSH page](https://tilde.team/wiki/?page=ssh) for information on connecting to tilde.team over SSH.

## What is a shell?
An operating system (OS) is the nuts and bolts that makes all the parts of your computer work together for you. At its core, the OS is not friendly for day to day computer usage. A shell is a user friendly "wrapper" around the operating system that allows you to use it easily. A shell can be graphical, like the Windows or Android GUIs. Or a shell can be text-based. A text based shell, also called a command line interface (or CLI), is a tool you can use to control the operating system by sending it text commands.

## What is a command?
Commands are simple words, often abbreviated, that make the system do things when typed into the shell. Some simple examples are 'ls' which lists the files in a directory, or 'cd' which changes your location to a new directory (cd = change directory), or 'exit' which logs you out of your current shell session. There are thousands of useful commands, but you only need to know a few to get started and be self-sustaining.

## What are the first commands a new user should learn?
When you're first starting to use a shell in a UNIX-like environment, you will want to be able to do the following things:
1. logging in and logging out
1. list the files or directories in a directory
1. move between directories

### Logging In, with `ssh`
Recall from the How-Do-I-Connect section above that you can use a SSH client to log into tilde.team. Once you're logged in, you can use the command line SSH client to log into any other shell server; in the example below, let's say you want to log into tilde.town from tilde.team.

Skipping some specifics for now, you can log into tilde.town from a tilde.team shell by using SSH as follows:
>`ssh tilde.team`
Some shell servers allow you to log in with nothing more than a username and password. But increasingly, many servers (like both tilde.team and tilde.town) require you to use ssh keys. To learn more about ssh keys, again, see our SSH page: https://tilde.team/wiki/?page=ssh

### Logging Out, with `logout` or `exit`
`logout` is a simple command you can use to log out of a shell. You could also use `exit`.

If you're still in your public_html directory, you should see a file called 'index.php' when you use the `ls` command. Let's peek inside 'index.php' as follows:

'testing.html' did not exist before you opened it with `nano`, so it was created for you.
Now, add some quick contents by opening the file for editing with `nano`, and adding whatever you want. Then Ctrl+x to save, you will have created a new file.

Be very, very careful with this command. Many a user, new and seasoned, has been stung by hastily deleting directories like this. This is also the source of the classic sysadmin joke/horror story about `rm -rf /` which deletes the entire file system.

## Commands have options and arguments.
When you look at the man page for a command like `ls`, you'll see in the DESCRIPTION section a number of **options** that you can use to modify how the command works. They look like `-a` or `-h` or `-l`. Try adding the `-a` option to `ls` and note the difference:

## The Filesystem Hierarchy
You already know that you get dropped into your "home" directory when you first log in. Your home directory is just one of many, many other directories on the system. All of these directories are organized under one master directory called the "root directory". The root directory is often referred to with a single forward slash, like this: /

All of these directories are organized under one master directory called the "root directory". The root directory is often referred to with a single forward slash, like this: /
You can list all the directories at the root level by using the `ls` command again, as follows:
> `ls /`
Want to check out some of the directories you see in root? You could either `cd` into them and `ls` the contents, or just `ls` the comments directly as follows:

> `ls /etc`
This would display the contents of the "etc" directory, which itself lives in the "root" directory. Notice that the command uses "/" + "etc" to create a path to the destination. In "etc" is another directory called "cron.d", and you can use the same principle to view its contents:

You now know enough to look around the file system. Note that most GNU+Linux systems (like tilde.team) adhere somewhat to an organization scheme called the Filesystem Hierarchy Standard ([Wikipedia link](https://en.wikipedia.org/wiki/Filesystem_Hierarchy_Standard)). This is another subject for you to read up on later.

## How can I keep my things private, or share them with others?
As you explore the filesystem, you might bump into some directories that won't let you in. For example, if you try to `cd` into the home directory for the root user (not the same as the root directory), you'll see this error: "/root: Permission denied". This is because GNU+Linux systems maintain a "mode" for each file that limits which users can read, write or execute it.

You can change a file's mode with `chmod` one of two ways. The first is a symbolic way in which you add or subtract 'r', 'w', and/or 'x' (read, write, execute) to 'u', 'g', or 'o' (user, group, or other). For example:

This gives 'execute' privileges to members of filename.txt's group.
You can also use `chmod` numerically, through which you may set the user, group and other permissions all at once. For example:

Use `man chmod` to get a fuller understanding of `chmod`.
