Checking Disk Space with "df" or "du"

A simple way to get used disk space on your Linux system and summary of the available space, just type "df" or "du" command in a terminal. The command "df" stands for disk filesystem.

The "du" command on the other hand shows the disk space used by the files and directories in the current directory.

All all commands in linux, we also have options for this.

$ df [options]
$ du [options] 

Examples for your reference:

$ df -h

/dev/mapper/root      909G  728G  135G  85% /
