The Ultimate Guide: Checking Hard Disk Space in Linux

Hard disk space refers to the amount of storage capacity available on a hard disk drive (HDD) or solid-state drive (SSD). Checking hard disk space is crucial in Linux systems for various reasons. It helps users monitor storage usage, identify potential space issues, and optimize system performance by removing unnecessary files or programs.

To check hard disk space in Linux, there are several commands that can be used. The most common is the “df” command, which stands for “disk free.” This command provides a summary of the available disk space on all mounted file systems. To use the df command, simply type “df” in the terminal window and press enter.

Another useful command for checking hard disk space is the “du” command, which stands for “disk usage.” This command provides a detailed breakdown of the disk space usage for a specific directory or file. To use the du command, type “du” followed by the path to the directory or file you want to check. For example, to check the disk space usage for the “home” directory, you would type “du /home”.

1. df command

The df command is a crucial component of “how to check hard disk space in linux” because it provides a quick and easy way to get a summary of the available disk space on all mounted file systems.

To use the df command, simply type “df” in the terminal window and press enter. The output of the df command will be a list of all mounted file systems, along with the following information for each file system:

• Filesystem: The name of the file system.
• Size: The total size of the file system in 1024-byte blocks.
• Used: The amount of space that is currently being used on the file system in 1024-byte blocks.
• Available: The amount of free space that is available on the file system in 1024-byte blocks.
• Use%: The percentage of space that is currently being used on the file system.
• Mounted on: The mount point of the file system.

The df command is a versatile tool that can be used to check the disk space usage of a specific file system or of all mounted file systems. It is also possible to use the df command to check the disk space usage of a specific directory or file. To do this, simply use the “-h” option followed by the path to the directory or file. For example, to check the disk space usage of the “/home” directory, you would type the following command:

df -h /home

The df command is an essential tool for managing disk space in Linux systems. It is a simple and easy-to-use command that can provide valuable information about the disk space usage of your system.

2. du command
