Common Terminal Commands for Developers

In this tutorial provides an overview of common terminal commands used in the Linux/MacOS command-line interface. You will learn basic commands such as navigating directories, managing files, and accessing system information. The tutorial will guide you in using command-line tools such as ls, cd, mkdir, cp, rm, and more. By the end of this tutorial, you will have the skills to navigate and manipulate the command-line interface efficiently, which is the foundation for using the terminal in Linux or MacOS operating systems.

Key Commands & Navigation

Before we look at some common commands, I just want to note a few keyboard commands that are very helpful:

• Up Arrow: Will show your last command
• Down Arrow: Will show your next command
• Tab: Will auto-complete your command
• Ctrl + L: Will clear the screen
• Ctrl + C: Will cancel a command
• Ctrl + R: Will search for a command
• Ctrl + D: Will exit the terminal

Manual Command

On Linux and Mac, the man command is used to show the manual of any command that you can run in the terminal. So if you wanted to know more about the ls command, you could run:

  man ls

Unfortunately, if you are on Windows and using Git Bash, the man command is not included, however, you can just type the command that you want to know more about and then --help and you will get similar info:

  ls --help

You should be able to use the arrow keys or page up and down. When you are ready to exit, just press q.

The whoami Command

The whoami command will show you the current user that you are logged in as.

  whoami

The date Command

Another really simple one is the date command, which, surprise, will show you the current date and time.

  date

File System Navigation

Commands to navigate your file system are very important. You will be using them all the time. You won't remember every single command that you use, but these are the ones that you should remember.

Of course, you can group flags together. For example, if I want to see more info and view hidden files, I could do ls -l -a and even shorten it to ls -la.

Opening a Folder or File

If you want to open a file or a folder in the GUI from your terminal, the command is different depending on the OS.

Mac - open [dirname] Windows - start [dirname] Linux - xdg-open [dirname]

You can open folders, files and even URLs

  open https://traversymedia.com

Modifying Files & Directories

We can also do multiple commands at once with the && operator:

cd test2 && mkdir test3

Right angle bracket >

This symbol tells the system to output results into whatever you specify next. The target is usually a filename. You can use this symbol by itself to create a new file:

> [filename]

When you are done, hit ctrl+D

The cat (concatenate) Command

The cat command is a very common command and allows you to create single or multiple files, view content of a file, concatenate files and redirect output in terminal or files.

The most common thing I use it for is to display the contents of a file:

  cat [filename]

You can also view the contents of multiple files:

  cat [filename] [filename]

You can also create a file using the cat command:

  cat > [filename]

This will open up a new file and you can start typing. When you are done, you can press Ctrl + D to save and exit.

You can also append to a file:

  cat >> [filename]

This will open up the file and you can start typing. When you are done, you can press Ctrl + D to save and exit.

You can use it to show line numbers:

  cat -n [filename]

There are other uses as well, but as you can see, the cat command is very powerful.

The less Command

The less command is used to view the contents of a file. It is similar to the cat command, but it allows you to scroll up and down.

  less [filename]

To exit the less command, just press q.

The echo Command

The echo command is used to display messages, or to create and write to files. It is similar to the cat command, but it is used to display a single line of text.

  echo "Hello World"

You can also use it to create a file:

  echo "Hello World" > [filename]

You can also append to a file:

  echo "Hello World" >> [filename]

The nano Command

The nano command is a text editor that is installed by default on most Linux distributions, MacOS and you can even use it with Git Bash on Windows. It is very similar to the vim editor, but it is much easier to use.

You can open an existing file to edit or create a new file and open it with:

  nano [filename]

When you're ready to exit, just hit Ctrl + X and then Y to save and N to not save.

The head and tail Commands

The head command is used to output the first part of files. By default, it outputs the first 10 lines of each file. You can also specify the number of lines to output.

  head [filename]

You can also specify the number of lines to output:

  head -n 5 [filename]

The tail command is used to output the last part of files. By default, it outputs the last 10 lines of each file. You can also specify the number of lines to output.

  tail [filename]

You can also specify the number of lines to output:

  tail -n 5 [filename]

The grep Command

The grep command is used to search for a text pattern in a file. It is very powerful and can be used to search for a string or regular expression in a file or set of files.

  grep [searchterm] [filename]

You can also search for a string in multiple files:

  grep [searchterm] [filename] [filename]

There are a lot more things that you can do with the grep command, but it's a but more advanced.

The find command

The find command is extremely powerful and is used to find the location of files and directories based on conditions that you specify.

To start off by creating something to work with. Let's create 100 files in the current directory. This is one of those things that I talked about earlier where you can do certain things much faster than you could in the GUI. We already know that the touch command will create a file. It can also be used to create multiple files.

  touch file-{001..100}.txt

Now we have 100 .txt files in the current directory. Something that would have taken a lot longer to do in the GUI.

Let's do something very simple and find a specific file. The format looks like this:

  find [dirname] -name [filename]

Let's find the file called file-001.txt:

  find . -name "file-001.txt"

This will look in the current directory, which is represented with a dot.

We can look in other directories as well. Let's create a file in our home folder called test.txt

  touch ~/test.txt

To find that file:

  find ~/ -name "test.txt"

We can look for files that match a certain pattern as well. Let's find all files that start with file-:

  find . -name "file-*"

We can search for files that are empty:

  find . -empty

Let's append some text to the file file-002.txt. We could use the cat command, like I showed you earlier, but we can also use the echo command:

  echo "Hello World" >> file-002.txt

Now if we find the empty files again, we will see that file-002.txt is no longer empty:

  find . -empty

We can remove all of the files that we created with this command:

  find . -name "file-*" -delete
  rm -f file-* # This will also work

There is so much more that you can do with the find command, but it goes beyond the scope of this tutorial.

Piping

Piping is very powerful. It is a way of redirecting standard output to another destination, such as another file. Let's actually use the find command to find a list of files and then pipe them to a new file.

First, we'll create 10 files:

touch file-{001..010}.txt

Now, let's pipe the result from our find into a new file named output.txt

find . -name "file-0*" > output.txt

You can see the results now in the new file:

cat output.txt

Creating a Symlink

A symlink is a special type of file that points to another file. It is a shortcut to the original file. It is useful when you want to access a file in a different location without having to copy it.

We can use the ln command to create a symlink:

  ln -s [filename] [symlinkname]

You can remove a symlink with the rm command:

  rm [symlinkname]

If you're on Windows and you are not using something like Git Bash, you can use the mklink command:

  mklink [symlinkname] [filename]

File Compression

tar is a program for concatenating multiple files into one big file called a tarball and reversing this process by extracting the files from the tarball.

• -c : Creates Archive
• -x : Extract the archive
• -f : creates archive with given filename
• -t : displays or lists files in archived file
• -u : archives and adds to an existing archive file
• -v : Displays Verbose Information
• -A : Concatenates the archive files
• -z : zip, tells tar command that creates tar file using gzip
• -j : filter archive tar file using tbzip
• -W : Verify a archive file
• -r : update or add file or directory in already existed .tar file

The history Command

Used to display the history of commands that you have run.

  history

You can also use the ! to run a command from the history.

  !100

This will run the command that is in the 100th position in the history.

Linux Server Setup: Deploying MERN App on Linux Server

These are the steps to setup an Ubuntu server from scratch and deploy a MERN app with the PM2 process manager and Nginx. We are using Linode, but you could just as well use a different cloud provider or your own machine or VM.

• Create an account at Linode
• Click on Create Linode
• Choose your server options (OS, region, etc)

SSH Keys

You will see on the setup page an area to add an SSH key.

There are a few ways that you can log into your server. You can use passwords, however, if you want to be more secure, I would suggest setting up SSH keys and then disabling passwords. That way you can only log in to your server from a PC that has the correct keys setup.

I am going to show you how to setup authentication with SSH, but if you want to just use a password, you can skip most of this stuff.

You need to generate an SSH key on your local machine to login to your server remotely. Open your terminal and type

ssh-keygen

By default, it will create your public and private key files in the .ssh directory on your local machine and name them id_rsa and id_rsa.pub. You can change this if you want, just make sure when it asks, you put the entire path to the key as well as the filename. I am using id_rsa_linode

Once you do that, you need to copy the public key. You can use the cat command and then copy the key

cat ~/.ssh/id_rsa_linode.pub

Copy the key. It will look something like this:

ssh-rsa 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 trave@ASUS

Now paste that into the Linode.com textarea and name it (eg.My PC)

At some point, you will be asked to enter a root password for your server as well.

Connecting as Root

Finish the setup and then you will be taken to your dashboard. The status will probably say Provisioning. Wait until it says Running and then open your local machine's terminal and connect as root. Of course you want to use your own server's IP address

ssh root@69.164.222.31

At this point, passwords are enabled, so you will be asked for your root password.

If you authenticate and login, you should see a welcome message and your prompt should now say root@localhost:~#. This is your remote server

I usually suggest updating and upgrading your packages

sudo apt update
sudo apt upgrade

Create a new user

Right now you are logged in as root and it is a good idea to create a new account. Using the root account can be a security risk.

You can check your current user with the command:

whoami

It will say root right noe.

Let's add a new user. I am going to call my user brad

adduser brad

Just hit enter through all the questions. You will be asked for a use password as well.

You can use the following command to see the user info including the groups it belongs to

id brad

Now, let's add this user to the "sudo" group, which will give them root privileges.

usermod -aG sudo brad

Now if you run the following command, you should see sudo

id brad

Add SSH keys for new account

If you are using SSH, you will want to setup SSH keys for the new account. We do this by adding it to a file called authorized_keys in the users directory.

Go to the new users home directory

cd /home/brad

Create a .ssh directory and go into it

mkdir .ssh
cd .ssh

Create a new file called authorized_keys

touch authorized_keys

Now you want to put your public key in that file. You can open it with a simpl text editor called nano

sudo nano authorized_keys

Now you can paste your key in here. Just repeat the step above where we ran cat and then the location of your public key. IMPORTANT: Make sure you open a new terminal for this that is not logged into your server.

Now paste the key in the file and hi ctrl or cmd+X then hit Y to save and hit enter again

Disabling passwords

This is an extra security step. Like I said earlier, we can disable passwords so that only your local machine with the correct SSH keys can login.

Open the following file on your server

sudo nano /etc/ssh/sshd_config

Look for where it says

PasswordAuthentication Yes

Remove the # if there is one and change the Yes to No

If you want to disable root login all together you could change permitRootLogin to no as well. Be sure to remove the # sign becayse that comments the line out.

Save the file by exiting (ctrl+x) and hit Y to save.

Now you need to reset the sshd service

sudo systemctl restart sshd

Now you can logout by just typing logout

Try logging back in with your user (Use your username and server's IP)

ssh brad@69.164.222.31

If you get a message that says "Publick key denied" or something like that, run the following commands:

eval `ssh-agent -s`
ssh-add ~/.ssh/id_rsa_linode     # replace this with whatever you called your key file

try logging in again and you should see the welcome message and not have to type in any password.

Node.js setup

Now that we have provisioned our server and we have a user setup with SSH keys, it's time to start setting up our app environment. Let's start by installing Node.js

We can install Node.js with curl using the following commands

curl -fsSL https://deb.nodesource.com/setup_18.x | sudo -E bash -
sudo apt-get install -y nodejs

# Check to see if node was installed
node --version
npm --version

Get files on the server

We want to get our application files onto the server. We will use Git for this. I am using the goal setter app from my MERN stack series on YouTube

On your SERVER, go to where you want the app to live and clone the repo you want to deply from GitHub (or where ever else)

Here is the repo I will be using. Feel free to deploy the same app: https://github.com/bradtraversy/mern-tutorial

mkdir sites
cd sites
git clone https://github.com/bradtraversy/mern-tutorial.git

Now I should have a folder called mern-tutorial with all of my files and folders.

App setup

There are a few things that we need to do including setting up the .ENV file, installing dependencies and building our static assets for React.

.env file

With this particular application, I create a .envexample file because I did not want to push the actual .env file to GitHub. So you need to first rename that .envexample:

mv .envexample .env

# To check
ls -a

Now we need to edit that file

sudo nano .env

Change the NODE_ENV to "production" and change the MONGO_URI to your own. You can create a mongodb Atlas database here

Exit with saving.

Dependencies & Build

We need to install the server dependencies. This should be run from the root of the mern-tutorial folder. NOT the backend folder.

npm install

Install frontend deps:

cd frontend
npm install

We need to build our static assets as well. Do this from the frontend folder

npm run build

Run the app

Now we should be able to run the app like we do on our local machine. Go into the root and run

npm start

If you go to your ip and port 5000, you should see your app. In my case, I would go to

http://69.164.222.31:5000

Even though we see our app running, we are not done. We don't want to leave a terminal open with npm start. We also don't want to have to go to port 5000. So let's fix that.

Stop the app from running with ctrl+C

PM2 Setup

PM2 is a production process manager fro Node.js. It allows us to keep Node apps running without having to have terminal open with npm start, etc like we do for development.

Let's first install PM2 globally with NPM

sudo npm install -g pm2

Run with PM2

pm2 start backend/server.js   # or whatever your entry file is

Now if you go back to your server IP and port 5000, you will see it running. You could even close your terminal and it will still be running

There are other pm2 commands for various tasks as well that are pretty self explanatory:

• pm2 show app
• pm2 status
• pm2 restart app
• pm2 stop app
• pm2 logs (Show log stream)
• pm2 flush (Clear logs)

Firewall Setup

Obviously we don't want users to have to enter a port of 5000 or anything else. We are going to solve that by using a server called NGINX. Before we set that up, lets setup a firewall so that people can not directly access any port except ports for ssh, http and https

The firewall we are using is called UFW. Let's enable it.

  sudo ufw enable

You will notice now if you go to the site using :5000, it will not work. That is because we setup a firewall to block all ports.

You can check the status of the firewall with

sudo ufw status

Now let's open the ports that we need which are 22, 80 and 443

sudo ufw allow ssh (Port 22)
sudo ufw allow http (Port 80)
sudo ufw allow https (Port 443)

Setup NGINX

Now we need to install NGINX to serve our app on port 80, which is the http port

sudo apt install nginx

If you visit your IP address with no port number, you will see a Welcome to nginx! page.

Now we need to configure a proxy for our MERN app.

Open the following config file

sudo nano /etc/nginx/sites-available/default

Find the location / area and replace with this

location / {
        proxy_pass http://localhost:5000;    # or which other port your app runs on
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }

Above that, you can also put the domain that you plan on using:

server_name yourdomain.com www.yourdomain.com;

Save and close the file

You can check your nginx configuration with the following command

sudo nginx -t

Now restart the NGINX service:

sudo service nginx restart

Now you should see your app when you go to your IP address in the browser.

Domain Name

You probably don't want to use your IP address to access your app in the browser. So let's go over setting your domain with a Linode.

You need to register your domain. It doesn't matter who you use for a registrar. I use Namecheap, but you could use Godaddy, Google Domains or anyone else.

You need to change the nameservers with your Domain registrar. The process can vary depending on who you use. With Namecheap, the option is right on the details page.

You want to add the following nameservers:

• ns1.linode.com
• ns2.linode.com
• ns3.linode.com
• ns4.linode.com
• ns5.linode.com

Technically this could take up to 48 hours, but it almost never takes that long. In my own experience, it is usually 30 - 90 minutes.

Set your domain in Linode

Go to your dashboard and select Domains and then Create Domain

Add in your domain name and link to the Linode with your app, then submit the form.

Now you will see some info like SOA Record, NS Record, MX Record, etc. There are A records already added that link to your IP address, so you don't have to worry about that. If you wanted to add a subdomain, you could create an A record here for that.

Like I said, it may take a few hours, but you should be all set. You have now deployed your application.

if you want to make changes to your app, just push to github and run a git pull on your server. There are other tools to help automate your deployments, but I will go over that another time.

Set Up SSL

You can purchase an SSL and set it with your domain registrar or you can use Let's Encrypt and set one up for free using the following commands:

sudo add-apt-repository ppa:certbot/certbot
sudo apt-get update
sudo apt-get install python-certbot-nginx
sudo certbot --nginx -d yourdomain.com -d www.yourdomain.com

# Only valid for 90 days, test the renewal process with
certbot renew --dry-run
