Disk free (df)

Displaying all filesystems and their disk usage in human-readable form can be done through the df utility:

df --human

To check what type of file system you are using use the -T flag as follows:

df -T

To get a good description divided in Megabyte and Gygabyte:

sudo du -cha --max-depth=2 / | grep -E "M|G"

Instead to estimate and summarize file and directory space usage, use the disk usage du utility as follows:

du -hT

A common usage of the du utility is to check the root directory usage as follows:

du -h --max-depth=1 / | sort -n

If allocated a new disk, run the following command to list all storage devices in a tree-like format:

lsblk

To enlarge a current disk perform the following commands:

sudo growpart /dev/nvme0n1 1
lsblk

The commands to extend the file system differ depending on the file system type. For XFS file system usd

sudo xfs_growfs -d /

For Ext4 file system use the correspective:

sudo resize2fs /dev/<nvme0n1p...>
