      <description>&lt;p&gt;&lt;strong&gt;What happens when you execute &lt;code&gt;export&lt;/code&gt; in your terminal?&lt;/strong&gt;&lt;br&gt;
I'm going to answer this question very simply , with a natural language without using AI because - what the hell is writing with AI !!-&lt;br&gt;
When you execute &lt;code&gt;export&lt;/code&gt; your terminal return simply environment variables exported from your current session.&lt;/p&gt;

&lt;p&gt;&lt;a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.us-east-2.amazonaws.com%2Fuploads%2Farticles%2Ff4pz2c8938cpnes5haqg.png" class="article-body-image-wrapper"&gt;&lt;img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.us-east-2.amazonaws.com%2Fuploads%2Farticles%2Ff4pz2c8938cpnes5haqg.png" alt=" " width="800" height="570"&gt;&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;What does it mean an environment variable?&lt;/strong&gt;&lt;br&gt;
It's an information that your system and programs use to know in which environment it should execute.&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;example:
&lt;/li&gt;
&lt;/ul&gt;
&lt;div class="highlight js-code-highlight"&gt;
&lt;pre class="highlight plaintext"&gt;&lt;code&gt;HOME="/home/houda-belhad"
&lt;/code&gt;&lt;/pre&gt;

&lt;/div&gt;


&lt;p&gt;means your home directory is /home/houda-belhad&lt;br&gt;
&lt;strong&gt;Most important variables:&lt;/strong&gt;&lt;br&gt;
-&lt;code&gt;PATH&lt;/code&gt;:&lt;br&gt;
&lt;/p&gt;

&lt;div class="highlight js-code-highlight"&gt;
&lt;pre class="highlight plaintext"&gt;&lt;code&gt;PATH="/home/houda-belhad/.nvm/versions/node/v22.23.2/bin:..."
&lt;/code&gt;&lt;/pre&gt;

&lt;/div&gt;



&lt;p&gt;&lt;code&gt;PATH&lt;/code&gt; indicate to your linux OS where to find the executable programs when you type a command.&lt;br&gt;
So when you type &lt;code&gt;node&lt;/code&gt; , linux will go find it in your directory of &lt;code&gt;PATH&lt;/code&gt;.&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;
&lt;code&gt;PWD&lt;/code&gt;:
&lt;/li&gt;
&lt;/ul&gt;

&lt;div class="highlight js-code-highlight"&gt;
&lt;pre class="highlight plaintext"&gt;&lt;code&gt;PWD="/home/houda-belhad"
&lt;/code&gt;&lt;/pre&gt;

&lt;/div&gt;



&lt;p&gt;It's your current directory! your terminal was actually there /home/houda-belhad.&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;
&lt;code&gt;LANG&lt;/code&gt;
&lt;/li&gt;
&lt;/ul&gt;

&lt;div class="highlight js-code-highlight"&gt;
&lt;pre class="highlight plaintext"&gt;&lt;code&gt;LANG="en_US.UTF-8"
&lt;/code&gt;&lt;/pre&gt;

&lt;/div&gt;



&lt;p&gt;it defines the language used by your OS.&lt;/p&gt;

&lt;p&gt;That's it , want to stay simple for someone who's discovering Bash and Terminals world for the first time . Follow my posts for more deep informations !!&lt;/p&gt;
