Linux Check Disk Space Command To View System Disk Usage

To check the disk space usage on a Linux system, you can use the df command.

Here's an example of how to use df to display the amount of free and used space on all the mounted filesystems:

$ df -h

The -h option tells df to display the sizes in "human-readable" format, with sizes expressed in bytes, kilobytes, megabytes, and so on.

You can also use df to display the disk space usage for a specific filesystem or directory. For example:

$ df -h /

This will display the disk space usage for the root filesystem (/).

Another useful command for checking disk space usage is du, which displays the amount of space used by a specific directory and its subdirectories. For example:

$ du -sh /home

This will display the total space used by the /home directory and its subdirectories.

Note: The specific options and syntax for these commands may vary depending on your Linux distribution and version. Consult the df and du man pages or documentation for your system for more information.
