Understanding the Linux file system hierarchy is crucial when managing your server. Sometimes, you may find yourself in a situation where system directories like /bin, /var, and others seem to be missing in your root partition. This article will explain why this might be happening and how to navigate your way around it.
If you’re not seeing directories like /bin, /var, and others in your root partition, it’s likely because you’re currently in the /root directory, not the filesystem root directory (/). Simply navigate to the filesystem root directory using the cd / command and you should be able to see the missing directories.
Understanding the Linux File System Structure
Before we delve into the issue, it’s important to understand the Linux file system structure. In Linux, the file system starts from a root directory, denoted as /. This is not to be confused with the /root directory, which is the home directory for the root user.
The root directory (/) is the top-level directory in the Linux file system hierarchy. It contains several other directories, including /bin, /var, /etc, and others. Each of these directories has a specific purpose. For example, /bin contains essential binary files, /var holds variable data files, and /etc stores system configuration files.
The Issue: Missing Directories
Now, let’s address the issue at hand. If you’re logged in as the root user and you don’t see directories like /bin, /var, and others, it’s likely because you’re currently in the /root directory, not the filesystem root directory (/).
To confirm your current directory, you can use the pwd command. pwd stands for “print working directory.” It displays the path of the current directory you’re in. If the output of pwd shows /root, then you’re in the /root directory.
Navigating to the Filesystem Root Directory
To navigate to the filesystem root directory (/), you can use the cd / command. cd stands for “change directory.” It’s used to switch between file directories in Linux. The / parameter directs the command to the root directory.
Once you’re in the / directory, you can use the ls -al command to see the contents of the filesystem root. ls is a command to list directory contents, and the -al option tells the command to list the files in long format including hidden files.
Here, you should be able to see the /bin, /var, and other system directories.
Conclusion
In summary, if you’re not seeing the /bin, /var, and other system directories, it’s likely because you’re currently in the /root directory. To see the system directories, navigate to the filesystem root directory (/) using the cd / command and then use the ls -al command to view the contents.

Remember, practice makes perfect. The more you interact with the Linux file system, the more comfortable you’ll become with it. Happy navigating!
The /bin directory in the Linux file system hierarchy contains essential binary files, such as commands and utilities, that are necessary for the basic functioning of the system.
The /var directory is used to store variable data files, such as log files, databases, and other files that are expected to change in size or content while the system is running.
You can use the pwd command, which stands for "print working directory," to display the path of the current directory you’re in.
To navigate to the root directory (/), you can use the cd / command. cd stands for "change directory," and the / parameter directs the command to the root directory.
You can use the ls -al command to list the contents of the root directory. The ls command lists directory contents, and the -al option tells the command to list the files in long format, including hidden files.
You can visit the Linux Documentation Project for more information on the Linux file system structure. They provide comprehensive documentation and resources on various Linux topics.
