What is the difference between df and du in Linux?

The commands df and du are used to view file system usage.

The df command is used to display the disk space usage of the file system, including the total space, used space, remaining space, and usage rate of each file system. It shows the overall usage of the file system, including the total space and used space. The df command can help users understand the capacity and usage rate of the file system, so that appropriate measures can be taken when disk space is running low.

The ‘du’ command is used to estimate the disk space usage of files and directories. It can recursively calculate the size of files in the specified directory and its subdirectories, displaying the results in a readable format. The ‘du’ command shows the actual disk usage of the specified directory, helping users find large files or directories taking up disk space.

In summary, the df command displays the overall usage of the entire file system, while the du command shows the actual disk usage of a specific directory.
