Linux Basics

Getting Ready

Installing the secure shell extension

To access Merlin, you'll need a secure shell client.

If you're using a Windows-based device: install Google Chrome, open up Chrome and search "Secure Shell Extension", install the extension.

If you're using a Mac or Linux based device, it probably already has a built-in client which can be accessed from the terminal.

You will need a connection string to access the server.

Obtaining an account

Fill out this form (if you haven't already) and wait for your credentials to be provided (via email).

Once your account is obtained, open up the "Connection Dialogue", and input the connection string. It will prompt you for your password, input it and continue to the "shell" (for further reference).

Navigating the Shell

In order to see what our working directory is inside the shell, we are going to use pwd which stands for "print the working directory". You can use the command by typing it in and hitting <RETURN>.

first-last@codermerlin:~$  pwd

After using the command you should see something like the below console line. As long as you haven't moved in the directory you should start off in the home directory.

/home/first-last 

Next, let's try the ls command which will list the directories and files in the working directory.

first-last@codermerlin:~$  ls

However no files or directories have been created yet, so there won't be anything to display.

We can make a directory by using the command mkdir

first-last@codermerlin:~$  mkdir firstDirectory

To enter the directory simply use the command "cd <SPACE> directoryName".

first-last@codermerlin:~$  cd firstDirectory

And if we use the pwd command now, we should see that we are in the created directory.

first-last@codermerlin:~$  pwd

/home/first-last/firstDirectory 

Now let's navigate out of the current directory. Using the previous cd command we can use "../" to go back one directory (which can be chained together, e.g. ../../../, ".." just replaces the current directory name), leave it blank to return to the home directory or use "~" to also get to the home directory.

first-last@codermerlin:~$  cd ../

Now that we have returned to the home directory, let's try listing again:

first-last@codermerlin:~$  ls

You should now see the directory previously added.

firstDirectory
