How to permanently set $PATH on Linux/Unix

How to Permanently Set $PATH on Linux/Unix 🚀

Have you ever encountered the frustrating issue of having to reset your $PATH variable every time you start a new session in Linux or Unix? Fear not, for I have the solution you seek! In this guide, I will walk you through the process of permanently setting your $PATH, so you can breeze through your terminal sessions without having to set it again and again. Let's dive in! 💪🔥

The Problem 😫

As mentioned in the context, the issue at hand is that the changes made to the $PATH variable using the export command are not persistent across different terminal sessions. Every time you exit the terminal, the updated $PATH is lost, causing inconvenience and wasted time.

The Solution ✨

To permanently set your $PATH on Linux/Unix, you need to modify a configuration file that is read during startup. The specific file to edit depends on the distribution you are using. Let's explore these options:

For Ubuntu and Debian-based Distributions 🐧

1. Open a terminal.

2. In the terminal, enter the following command to edit the .bashrc file using a text editor (such as nano or vim):

nano ~/.bashrc

1. Scroll to the end of the file and find the line that starts with export PATH=.

2. Add your desired directory to the $PATH. For example, if you want to add the directory /path/to/dir, add the following line:

export PATH="$PATH:/path/to/dir"

1. Save the file by pressing Ctrl + X, then Y, and finally Enter to confirm the filename.

For Red Hat-based Distributions (e.g., CentOS, Fedora) 🎩

1. Open a terminal.

2. In the terminal, enter the following command to edit the .bash_profile file:

nano ~/.bash_profile

1. Scroll to the end of the file and find the line that starts with export PATH=.

2. Add your desired directory to the $PATH, following the same format as described in the previous example.

3. Save the file using the same steps as mentioned earlier.

For other Linux/Unix Distributions 🐧

1. Open a terminal.

2. In the terminal, enter the following command to edit the .bash_profile or .bashrc file (depending on the distribution):

nano ~/.bash_profile

or

nano ~/.bashrc

1. Similar to the previous steps, find the line that starts with export PATH= and append your desired directory.

2. Save the file as mentioned before.

Verifying the Changes ✅

To ensure that the changes to your $PATH are in effect, you can either open a new terminal session or run the following command in your current terminal:

source ~/.bashrc

or

source ~/.bash_profile

This command reloads the configuration file, and you should now see the updated $PATH when you run echo $PATH.

📣 Take Action and Enjoy the Permanence!

Congratulations! You have successfully learned how to permanently set your $PATH on Linux/Unix. No more frustrations with lost $PATH settings! Now you can focus on your work or projects without worrying about resetting your $PATH every time you start a new session.
