Linux: Find Out How Much Disk Space Left On Hard Drive

To find out how much disk space is left on a hard drive on a Linux system, you can use the df command. df is a utility that displays information about the available and used disk space on the system.

Here's an example of how to use df to find out how much disk space is left on a hard drive:

$ df -h

The -h option tells df to display the sizes of the file systems in "human-readable" format, meaning that the sizes will be displayed in a more readable format (e.g., in megabytes or gigabytes, rather than in blocks).

This will display a list of the file systems on the system, along with their sizes, used space, and available space. The hard drive will typically be represented by a file system with a mount point of / (the root file system).

For example, the output might look something like this:

Filesystem      Size  Used Avail Use% Mounted on
/dev/sda1       9.9G  3.7G  6.2G  38% /

This indicates that the hard drive (/dev/sda1) has a total size of 9.9 GB, with 3.7 GB used and 6.2 GB available.

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