Keeping track of disk utilization information is on system administrators' (and others') daily to-do list. Linux has a few built-in utilities that help provide that information.

df

The df command stands for "disk-free," and shows available and used disk space on the Linux system.
df -h shows disk space in human-readable format
df -a shows the file system's complete disk usage even if the Available field is 0

df -T shows the disk usage along with each block's filesystem type (e.g., xfs, ext2, ext3, btrfs, etc.)
df -i shows used and free inodes

du

du shows the disk usage of files, folders, etc. in the default kilobyte size
du -h shows disk usage in human-readable format for all directories and subdirectories
du -a shows disk usage for all files
du -s provides total disk space used by a particular file or directory

The following commands will check your total space and your utilized space.

These are most of the built-in utilities for checking file space in Linux. There are many similar tools, like Disks (GUI), Ncdu, etc., that also show disk space utilization. Do you have a favorite tool that's not on this list? Please share in the comments.
