Executing "export" in a terminal!
What happens when you execute export in your terminal? I'm going to answer this question very simply , with a natural language without using AI because - what the hell is writing with AI !!- When you execute export your terminal return simply environment variables exported from your current session. What does it mean an environment variable? It's an information that your system and programs use…
When you run the "export" command in your terminal, it simply displays the environment variables that are currently active in your session. An environment variable is a piece of information that your system and programs rely on to understand the environment they are operating in.
For example, the variable "HOME=/home/houda-belhad" tells your system that your home directory is "/home/houda-belhad". One of the most important variables is "PATH", which is set to "/home/houda-belhad/.nvm/versions/node/v22.23.2/bin:..." This tells your Linux operating system where to locate executable programs when you type a command. For instance, when you type "node", Linux knows to look for it in the directory specified by PATH.
Another key variable is "PWD", which stands for "present working directory". In this case, "PWD=/home/houda-belhad" indicates that your current directory, the one you are currently working in, is "/home/houda-belhad". Lastly, the "LANG" variable, set to "en_US.UTF-8", determines the language used by your operating system. This covers the basics of what happens when you execute "export" in your terminal for someone just starting out with Bash and terminals.
