Developers need to know basic Unix commands. Some tasks necessary need
to be done using git bash, mac terminal, or window command prompt. In
this tutorial, we will use git bash to learn the basics of the Unix
command which you may need as a developer. This is not an exhaustive
list but it is enough for daily uses. To make use of git bash first
you should install
<a href="https://git-scm.com/">git</a>. You can install by just
clicking the next button up to the end of the installation.

<h3 id="navigating-directory">Navigating directory</h3>
<p>Now, let's go to the Desktop using cd(change directory).</p>
<pre><code class="lang-sh">Asabeneh<span class="hljs-variable">@DESKTOP</span>-KGC1AKC MINGW64 ~<span class="hljs-variable">$ </span>cd Desktop

<p>To check where you are at, use the <em>pwd</em> command age</p>
<pre><code class="lang-sh">Asabeneh<span class="hljs-meta">@DESKTOP</span>-KGC1AKC MINGW64 ~/Desktop$ pwd
<span class="hljs-regexp">/c/</span>Users<span class="hljs-regexp">/Asabeneh/</span>Desktop
</code></pre>
<p>
We use <em>cd</em> to get into a directory(folder) and we use
<em>cd..</em> to get out from a directory, in other words, we use
<em>cd</em> to go forward into a directory and <em>cd ..</em> to go
backward from a directory.
</p>
<h3 id="making-directory">Making Directory</h3>
<p>
Now, let's create a directory inside the Desktop. Call the name of
the directory, 10-days-of-code. You give it any name but I am in favor
of this name. Use the <em>mkdir</em> command to make a
directory(folder)
</p>
<pre><code class="lang-sh">Asabeneh@DESKTOP-KGC1AKC MINGW64 ~/Desktop$ mkdir <span class="hljs-number">10</span>-days-<span class="hljs-keyword">of</span>-<span class="hljs-keyword">code</span>

Now let's go to the 10-days-of-code folder using
<em>cd</em> command.

<p>
No files or directories were found in the 10-days-of-code folder
because we didn't create them yet. Let's create some
directories
</p>

<p>
Now let's check if there are some files or directories in the
10-days-of-code folder.

<p>Now, you see a day-1 folder that you created.</p>
<p>
Now let's create multiple folders at one and use <em>ls</em> to
see all the directories we have in the 10-days-of-code folder.
</p>
<p>Making multiple folders at once</p>

</code></pre>
<p>
As you can see, there is day-1.txt in the list. That means we have
created the day-1.txt file inside the 10-days-of-code folder. You can
also you
<em>ls -la</em> command to use the detailed view of the folders and
file.
</p>
<h3 id="opening-and-writing-on-file">Opening and writing on file</h3>
<p>
Now, let's open the day-1.txt file and add some text to it. We use
the
<em>nano</em> command to open and write.

<p><img src="/images/nano.png" alt="" /></p>
<p>
As you can see from the above figure, the cursor is active and you can
write on the pad. You can only use arrow keys to move the cursor left,
right, up, and down. Let's write some text on the opened pad.
There are instructors at the bottom that tells how to exit. For
instance ctrl + x is to exit. When you exit either you save or cancel
which comes when you click ctrl + x.
</p>
<p><img src="/images/writting_on_nano.png" alt="" /></p>

Now you can save the modified file by writing Y or you can cancel it
by clicking ctrl + c.

<h2 id="git-and-github">Git and GitHub</h2>
<p>
Git is a version control software. In one way or the other you may
need to use a git and a GitHub together.
</p>
<p>
You need to use git and GitHub either to store your projects on the
cloud or to collaborate with your team. This means it allows
developers or writers to work on the same project even if they are
located in different locations.
</p>
<p>
Version control is a means of recording changes to a file or set of
files over time so that you can recall specific versions later.

</p>
<h3 id="1-install-git">1. Install Git</h3>
<p>First, you need to install the version control software, Git.</p>
<ul>
<li>Git: Install <a href="https://git-scm.com/downloads">git</a></li>
</ul>
<h3 id="2-checking-status-of-the-repository">
2. Checking status of the repository
</h3>
<p>
The <em>git status</em> command allows you to know the status of the
project: If it is
</p>
<ul>
<li>initiated</li>
<li>modified</li>
<li>staged</li>
</ul>
<p>
We can write the command <em>git status</em> at any time. It is a
means to to check what is happening on your project.
</p>
<h3 id="3-configure-your-name-and-your-email">
3. Configure your name and your email
</h3>
<p>
Open the Git bash if your device is Windows, or open the Mac terminal
if your device is MacOS and then write the following commands
</p>
<pre><code class="lang-shell">git config --global user<span class="hljs-selector-class">.name</span> <span class="hljs-string">'yourname'</span>
git config --global user<span class="hljs-selector-class">.email</span> <span class="hljs-string">'youremail'</span>
</code></pre>
<h3 id="4-create-a-local-git-repository">
4. Create a local git repository
</h3>
<p>
In this step, you will create a folder (directory) for your project. A
project is just a simple folder that stores all the files related to a
certain project. A local repository is a project or a folder that is
on your computer.
</p>
<p>
If your Git bash is not opened, go to start and type git bash. Git
terminal will popup on Windows devices. If it is MasOS just open the
Mac terminal. On the terminal write:
</p>
<pre><code class="lang-shell"><span class="hljs-built_in">mkdir</span> project_name
<span class="hljs-built_in">cd</span> project_name
</code></pre>
<p>
By the way, you can also create the folders the usual way using on the
GUI(Graphical User Interface) of Windows or Mac.
</p>
<h3 id="5-initialize-git">5. Initialize Git</h3>
<p>
After creating a new local repository or in an existing local
repository, initialize the repository by the following command:
</p>
<pre><code class="lang-shell"><span class="hljs-attribute"> git init</span>
</code></pre>
<p>
Once, the repository is initialized git tracks the changes in the
files and folders of the project.
</p>
<h3 id="6-add-file-to-the-staging-area">
6. Add file to the staging area
</h3>
<p>
The file can be added to the staging area in multiple ways. To add a
single file, we use the <em>git add</em> command followed by a file
name
</p>
<pre><code class="lang-shell"> git <span class="hljs-keyword">add</span><span class="bash"> filename</span>
</code></pre>
<p>
To add multiple files using their file names using the command
<em>git add</em> followed by file names
</p>
<pre><code class="lang-shell"> git <span class="hljs-keyword">add</span><span class="bash"> filename1 filename2</span>
</code></pre>
<p>
Sometimes, we may make a lot of changes, and adding files one by one
is tiring and not product. Therefore, we can use a short and product
way. The
<em>git add</em> command followed by a dot allows adding files and
folders at once to the stage area. Remember, there is a space between
the add and the dot.
</p>
<p>To add all files and folders at once</p>
<pre><code class="lang-shell"> git <span class="hljs-keyword">add</span><span class="bash"> .</span>
</code></pre>
<h3 id="7-unstage-a-file">7. Unstage a file</h3>
<pre><code class="lang-shell"> git <span class="hljs-keyword">reset</span> <span class="hljs-keyword">HEAD</span> filename
</code></pre>
<h3 id="8-commit-the-changes">8. Commit the changes</h3>
<p>
Commit means taking a snapshot or a copy of your file at that point in
time. You may associate it with saving a file with a new name (save
as).
</p>
<pre><code class="lang-shell"> <span class="hljs-attribute">git</span> commit -m <span class="hljs-string">'your message'</span>
</code></pre>
<p>
Your commit message has to be associated with the changes or
modifications you make.
</p>
<h3 id="9-git-log">9. Git log</h3>
<p>
The <em>git log</em> command allows knowing the commit history of the
project
</p>
<h3 id="10-git-check-out">10. Git check out</h3>
<p>
We can identify the commit id of each commit using the
<em>git log</em> command. Then we can make use of this id to retire
any previous commit.
</p>
<pre><code class="lang-sh">git checkout <span class="hljs-keyword">commit</span>-<span class="hljs-keyword">id</span>
</code></pre>
<h3 id="11-creating-a-branch">11. Creating a branch</h3>
<p>
You can create a copy of the master using a branch. You built an
awesome application. You like to keep this awesome application as it
is but you like to add some features. This is the time, you need
branching the master. The branch is the copy of the master at
branching instant. After branching, the branch and the master
don't see each other. You can create as many branches as you want.
</p>
<p>To create a branch:</p>
<ul>
<li>Only to create branch</li>
</ul>
<pre><code class="lang-shell"> git checkout branch-<span class="hljs-built_in">name</span>
</code></pre>
<p>To create branch:</p>
<ul>
<li>To create and checkout to the branch at the same time:</li>
</ul>
<pre><code class="lang-shell"> git checkout -<span class="hljs-selector-tag">b</span> branch-name
</code></pre>
<p>To switch between branches:</p>
<pre><code class="lang-shell"> git checkout main
git checkout branch-<span class="hljs-built_in">name</span>
</code></pre>
<p>To list down all the branches:</p>
<pre><code class="lang-shell"><span class="hljs-attribute"> git branch</span>
</code></pre>
<h3 id="12-create-account-on-github">12. Create account on GitHub</h3>
<p>
Now, create an account on GitHub and sign in using your emails and
password
</p>
<ul>
<li>GitHub Sign up on <a href="https://github.com/">GitHub</a></li>
</ul>
<h3 id="13-create-repository-on-github">
13. Create Repository on GitHub
</h3>
<p>
Go to <a href="https://github.com/">GitHub</a> and create a repository
by click the plus icon on the top right corner.
</p>
<h3 id="14-connecting-git-with-remote-repository">
14. Connecting git with remote repository
</h3>
<p>
In this step, you will connect your local git repository with your
remote GitHub repository
</p>
<pre><code class="lang-shell"> git remote <span class="hljs-keyword">add</span><span class="bash"> origin remote_repository_ul</span>
</code></pre>
<p>
The word origin could be any word. It is a means to assign the
repository URL. If this is step is passed without error, you are ready
to push it to your remote GitHub repository. Push means actually
uploading what you have on your local to remote repository.
</p>
<h3 id="15-push">15. Push</h3>
<p>
Before you push(upload), please commits any changes and if it is ready
push your files to your remote GitHub repository using the following
command.
</p>
<pre><code class="lang-shell"> git <span class="hljs-built_in">push</span> -u <span class="hljs-built_in">origin</span> master
</code></pre>
<h3 id="16-merge">16. Merge</h3>
<p>
When you work on an individual project or a team project you may have
different branches. Mostly you will have a master(main), develop and
other branches. Then you will merge other branches to your develop and
your develop to master. It is possible to merge any branches. For
instance, lets merge feature branch to develop
</p>
<pre><code class="lang-shell"> git checkout develop
git <span class="hljs-keyword">merge</span> feature
</code></pre>
<p>
Using the above code, now the develop and feature branches do have the
same content
</p>
<h3 id="17-pull">17. Pull</h3>
<p>
If your team merges new features to the develop, then you will be
behind, now you need to make your project to the current stage by
pulling from develop
</p>
<pre><code class="lang-shell"><span class="hljs-attribute"> git checkout yourbranch
git pull origin develop</span>
</code></pre>
<pre><code class="lang-sh"> git checkout develop
git merge yourbranch
git <span class="hljs-built_in">push</span> -u <span class="hljs-built_in">origin</span> develop
</code></pre>
<p>
If you are a sole developer that works by yourself then you can test
the
<em>git pull</em> command by modifying some of the files from your
remote repository and pull it using the <em>git pull</em> command.

<h3 id="18-git-clone">18. Git clone</h3>
<p>
GitHub allows downloading a project using a URL. It is the same as
downloading by clicking a download button from a website. To clone, go
to desktop or any location and write the command
<em>git clone URL</em>.
</p>
<p>
For instance, to clone this repository, you need to run the following
command
</p>
<pre><code class="lang-sh">Asabeneh<span class="hljs-variable">@DESKTOP</span>-KGC1AKC MINGW64 ~<span class="hljs-variable">$ </span>cd Desktop

<h3 id="21-the-gitignore-file">21. The .gitignore file</h3>
<p>Any file you committed could be pushed to a remote repository but sometimes you may not want to push everything you have on your local repository. For instance sensitive data such as email, password, bank account, API Keys and others. Therefore, any files or folders that is listed on the .ignore file will not be tracked by Git. Create a .ignore file on the top level of your project directory, on this file put file names or folder you would like to ignore</p>
