Knowing how to check hard drive space is an essential skill for any Linux user. It allows you to monitor the amount of free space available on your system and take steps to free up space if necessary. There are a few different ways to check hard drive space in Linux, and the method you use will depend on your distribution and preferences.
One of the most common ways to check hard drive space is to use the df command. The df command will display a list of all the mounted file systems on your system, along with the amount of free space available on each one. To use the df command, simply open a terminal window and type:
df
The output of the df command will look something like this:
Filesystem Size Used Avail Use% Mounted on /dev/sda1 20G 10G 10G 50% / /dev/sda2 10G 5G 5G 50% /home /dev/sda3 5G 2G 3G 40% /var
As you can see, the df command provides a quick and easy way to see how much free space is available on your hard drive. You can also use the df command to check the space usage of individual files and directories. To do this, simply pass the path to the file or directory as an argument to the df command. For example, to check the space usage of the /home directory, you would type:
df /home
Another way to check hard drive space in Linux is to use the du command. The du command will display the amount of space used by a specified file or directory. To use the du command, simply open a terminal window and type:
du /path/to/file_or_directory
For example, to check the space usage of the /home directory, you would type:
du /home
The output of the du command will look something like this:
4.0K /home/user/file1 8.0K /home/user/file2 12.0K /home/user/file3 ... 100K /home/user/directory1 200K /home/user/directory2 ... 1G /home
As you can see, the du command provides a more detailed view of how space is being used on your hard drive. You can use the du command to identify large files and directories that are taking up too much space.
Checking hard drive space is an important part of system maintenance. By regularly checking hard drive space, you can ensure that your system has enough free space to run smoothly and efficiently.
1. df Command
The df command is a powerful tool for checking hard drive space in Linux systems. It provides a quick and easy way to see how much free space is available on your hard drive, as well as other useful information such as the total size of the filesystem, the amount of space used, and the percentage of space used.

Syntax
The basic syntax of the df command is as follows:
df [options] [file...]
The most common options used with the df command are:
- -h: Display human-readable output
- -i: Display inode information
- -T: Display filesystem type
-
Output
The output of the df command is a table that contains the following information for each mounted filesystem:
- Filesystem: The name of the filesystem
- Size: The total size of the filesystem
- Used: The amount of space used on the filesystem
- Avail: The amount of free space available on the filesystem
- Use%: The percentage of space used on the filesystem
- Mounted on: The mount point of the filesystem
-
Examples
Here are a few examples of how to use the df command:
- To see a summary of all mounted filesystems, type the following command: df
- To see a detailed view of a specific filesystem, type the following command: df -i /dev/sda1
- To see a human-readable output, type the following command: df -h
-
Conclusion
The df command is a versatile tool that can be used to check hard drive space in Linux systems. It is a simple and easy-to-use command that can provide valuable information about your filesystems.
2. du command
The du command is a powerful tool for checking hard drive space in Linux systems. It provides a quick and easy way to see how much space is being used by a specified file or directory. This information can be helpful for identifying large files and directories that are taking up too much space.
The du command is often used in conjunction with the df command. The df command provides a summary of all mounted filesystems, while the du command provides a more detailed view of how space is being used on a specific filesystem. Together, these two commands can provide a comprehensive overview of hard drive space usage.
Here is an example of how to use the du command to check hard drive space usage:
du -h /home/user
This command will display a summary of the space usage for the /home/user directory. The output will look something like this:
10M /home/user/Documents 20M /home/user/Pictures 30M /home/user/Videos
As you can see, the du command can be a helpful tool for identifying large files and directories that are taking up too much space. This information can then be used to free up space on your hard drive.
3. File manager
A file manager is a computer program that provides a graphical user interface for managing files and directories. File managers allow users to create, delete, move, and rename files and directories, as well as view their contents. Some file managers also provide additional features, such as the ability to search for files and directories, compress and decompress files, and view file properties.
-
Title of Facet 1
File managers can be used to check hard drive space in Linux by providing a visual representation of the files and directories on the hard drive. This can be helpful for identifying large files and directories that are taking up too much space. Additionally, some file managers have built-in tools that can be used to analyze hard drive space usage and identify files and directories that can be deleted or moved to free up space.
-
Title of Facet 2
File managers can also be used to check hard drive space in Linux by providing a way to view the properties of files and directories. This can be helpful for identifying files and directories that are taking up a lot of space, as well as files and directories that have not been accessed in a long time and can be deleted or moved to free up space.
-
Title of Facet 3
File managers can also be used to check hard drive space in Linux by providing a way to search for files and directories. This can be helpful for finding large files and directories that are taking up too much space, as well as files and directories that have been lost or forgotten.
-
Title of Facet 4
File managers can also be used to check hard drive space in Linux by providing a way to compress and decompress files. This can be helpful for reducing the amount of space that files and directories take up on the hard drive.
In conclusion, file managers are a versatile tool that can be used to check hard drive space in Linux in a variety of ways. By providing a graphical user interface for managing files and directories, file managers make it easy to identify large files and directories that are taking up too much space, as well as files and directories that can be deleted or moved to free up space.
