Absolute Path vs. Relative Path Explained 

0

How do you know where specific data exists on a system? Through its path. A path is a unique location where a file or folder exists in an operating system’s file system, denoted by a mix of / and alphanumeric characters. In Linux, absolute and relative paths specify a directory or file’s location from the root directory and the current working directory, respectively. The root directory is the top-level directory in the file system, written as /. This article explains both path types in detail, how to find them in Linux, and which one you should use.

What Is an Absolute Path

An absolute path is the full location of a file on your Linux system, regardless of your current directory. In other words, an absolute path is the complete and accurate file or directory location that starts from the root directory (/).

The absolute path always starts at the absolute beginning of your hard drive and describes each step that you need to take via the filesystem to reach the desired location.

For example, /home/user/documents/file.txt is an absolute path in Linux that tells the operating system to start from / root, go to home, go to user, navigate to documents, and then access the file.txt file.

How to Find an Absolute Path in Linux

To find an absolute path in Linux, run the pwd (print working directory) command. Here is how.

  • Press Ctrl+Alt+T to open the terminal.
  • Run the cd command to move to the directory with the file or directory you need the absolute path for.
  • Use the pwd (print working directory) command to get the current directory’s absolute path.

What Is a Relative Path

A relative path is the location of a directory or file relative to your present working directory. As its name suggests, it changes depending on the directory; when you change the directory, the relative path also changes. Also, relative paths use special symbols for path simplification; they use . (dot) for the current directory and .. (double dot) for the parent directory.

For example, ./script.sh is a relative path in Linux that runs script.sh in the current directory.

How to Create a Relative Path in Linux

You can follow the steps below to link to a file through a relative path.

  • Make sure the file you need to link to is present on the same Linux server as the HTML file you are working with.
  • Ensure the path to the file is relative to the HTML file directory to create a relative path.
  • If the file is located in a subdirectory relative to the HTML file, move up one directory level using ../ and then specify the subdirectory.

What Is the Difference Between Absolute and Relative Paths in Linux

The main difference between absolute and relative paths in Linux is that an absolute path doesn’t depend on the current directory, while a relative path does. Moreover, an absolute path starts at the root directory (/), while a relative path does not start with (/). Furthermore, an absolute path follows each directory step by step, while a relative path is shorter and easier to type. Also, an absolute path is more reliable and clear than a relative path. Additionally, an absolute path works from any location and doesn’t change with the current directory; a relative path changes meaning as the current directory changes.

Should You Use an Absolute Path or a Relative Path in Linux

Whether you should use an absolute or relative path in Linux depends on your specific requirements. Use an absolute path for shell scripts, background jobs, editing system configuration files, and when accuracy is critical. Use relative paths for moving directories manually, working within a known or current project structure, and quick file operations.

Frequently Asked Questions

Q1. What is a path in Linux?

A path in Linux is the location of a file or folder: a combination of / and alphanumeric characters in the operating system’s file system.

Q2. Which is better, an absolute or relative path?

The better choice between an absolute and relative path depends on your requirements. An absolute path is better for shell scripts, background jobs, system configuration file editing, and accuracy; a relative path is better for manual directory navigation, known project structures, and quick file operations.

Hopefully, this clears up any doubts about an absolute path and a relative path in Linux. If any confusion or questions persist, leave us a comment.
