Title: How to manage disk space without duf command in Linux system?

In Linux systems, managing disk space is a very important task. Usually we use some command line tools to check disk usage, such as the common df command. However, sometimes you may encounter some situations, such as tools like duf not installed on the server, so how to manage disk space? This article will introduce some alternatives and give specific code examples.

1. Using the df command

Although there is no duf command, the df command that comes with the Linux system is a very commonly used disk space management tool. With the df command, you can easily view disk partition usage. The following is an example of using the df command to view disk space:

df -h

This command will list all mounted disk partitions and their usage, including used space, free space, usage and other information.

2. Use the du command

Another commonly used disk space management tool is the du command. With the du command, you can view the disk usage of a specified directory or file. The following is an example of using the du command to view the disk space usage of a specified directory:

du -h /path/to/directory

This command will list the disk space usage of each subdirectory and file in the specified directory.

3. Use the find command

In addition to the df and du commands, the find command is also a commonly used tool that can help you find and manage disk space. The following is an example of using the find command to find large files:

find /path/to/directory -type f -size +100M

This command will find files larger than 100MB in the specified directory and list their details.

4. Using the ncdu command

If you are not familiar with the command line, you can also use interactive tools like ncdu to manage disk space. ncdu can help you visually understand disk space usage and perform further operations. You can install and use ncdu through the following commands:

sudo apt-get install ncdu ncdu /path/to/directory

The above are some common methods and commands for managing disk space in Linux systems. Even if there are no tools like duf, you can also use these alternative methods. Easily manage disk space. I hope these code examples are helpful.
