How to Permanently Set $PATH in Linux

Unlocking the full potential of your Linux system involves understanding the importance of the $PATH variable, which serves as a roadmap for your operating system to locate and execute commands swiftly and effortlessly. However, if you find yourself repeatedly setting the $PATH every time you log in or reboot, it is time to learn how to permanently configure it.

In this comprehensive guide, we will walk you through the step-by-step process of setting the $PATH variable in Linux, ensuring that your customizations persist across sessions.

What is a $PATH Variable in Linux

The $PATH variable is a fundamental part of the Linux operating system, acting as a reference to locate executable files. It consists of a list of directories separated by colons (:) , with the system searching for commands in these directories when they are executed. Understanding the importance of the $PATH variable is crucial to effectively manage your command-line experience.

There are multiple approaches to permanently setting the $PATH variable in Linux and the two most common methods involve:

Each method has its advantages and disadvantages, so choose the one that best suits your needs. The PATH variable can also be set on a per-user basis or system-wide for all user accounts.

Check $PATH Variables in Linux

You can see your $PATH variables by running the following echo command:

Add a Directory to PATH Variable Linux

To temporarily add a directory, for example, /opt/sysadmin/scripts to your path, you can run the following command:

$ PATH=$PATH:/opt/sysadmin/scripts $ echo $PATH

One way to permanently set the $PATH variable is by modifying shell configuration files, such as .bashrc or .bash_profile . These files are executed each time you start a new shell session.

$ nano ~/.bashrc OR $ vim ~/.bashrc

Locate the line that begins with «export PATH attachment_8239″ aria-describedby=»caption-attachment-8239″ style=»width: 831px» > The .bashrc File in Linux

If you are unable to find this line, you can add it manually inside the file at the bottom of the page. As an example, I am adding the /opt/sysadmin/scripts directory path to my PATH using the command given below:

export PATH="$PATH: /opt/sysadmin/scripts"

To apply the changes, either open a new terminal or run the following command:

Note: The above method only works for user accounts.

Permanently Set $PATH for All Users

To permanently set system PATH for all users on the system, append the following lines at the end of the /etc/profile file. On some Linux distros, you can also use the /etc/bash.bashrc file (if it exists) but it should be sourced in /etc/profile for changes in it to work.

PATH="$PATH:/opt/sysadmin/scripts" export $PATH OR $export PATH="$PATH:/opt/sysadmin/scripts"

Alternatively, instead of making changes directly in the /etc/profile (which is not recommended), you can create a script (ending with the .sh extension) under the directory /etc/profile.d (if it exists) and make the changes in that script.

$ sudo vim /etc/profile.d/set_system_path.sh

Append the following line in it:

export PATH="$PATH:/opt/sysadmin/scripts"

Next, source the ~/.bashrc or /etc/profile or /etc/bash.bashrc (depending on the one you used), for the changes to take effect.

$ source ~/.bashrc OR $ source /etc/profile OR $ source /etc/bash.bashrc

Then confirm that your PATH has been set correctly:

$ echo $PATH /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/opt/sysadmin/scripts:/opt/sysadmin/scripts

Set PATH Variable in /etc/environment File

Another approach to permanently setting the $PATH a variable is by using environment-specific files. Two common files used for this purpose are /etc/environment and /etc/profile.d/.

Next, locate the line that begins with «PATH /opt/sysadmin/scripts:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/>

To apply the changes, reboot your system or run the following command:

After making modifications to the $PATH variable, it’s crucial to verify that the changes have taken effect.

This will display the updated $PATH variable, including the directories you added. Ensure that the desired directories are now part of the $PATH variable.

Conclusion

To make the most of your Linux system, it’s a must for you to understand the $PATH variable that acts like a map and helps your computer find and run commands quickly.

If you are tired of setting $PATH every time you log in or restart your computer, better to set it permanently using the step-by-step guidelines presented in the above article.

If you have managed to do this process, you will have a better command-line experience on your Linux system.
