How to Check Free Disk Space in Linux? Remaining space available

The easiest way to check for free disk space in Linux is by using the DF command:

df -h

Simply type this command into a terminal and press enter. The -h option adds a human readable output. Run the command in the mount that you want to see. You do not need to run it in the top level; you can run it anywhere in that mount and it will show the free disk space available, as well as the total.
