du Command - Check Directory Capacity
You can check the directory capacity with the du command. If no directory name is specified, the current directory will be the target.
du DirectoryName
This is a sample to check the directory capacity with du.
du templates
This is a sample output result.

The capacity is displayed in kilobytes for each directory and subdirectory.
To display in an easy-to-understand manner with units
Use the "-h" option to clearly display the units of the du command.
du -h
The output result has a unit.
Filesystem Size Used Avail Use% Mounted on udev 3.9G 0 3.9G 0% /dev tmpfs 794M 736K 793M 1% /run /dev/sda1 29G 4.1G 25G 15% / tmpfs 3.9G 8.0K 3.9G 1% /dev/shm tmpfs 5.0M 0 5.0M 0% /run/lock tmpfs 3.9G 0 3.9G 0% /sys/fs/cgroup /dev/sda15 105M 3.6M 101M 4% /boot/efi /dev/sdc1 1007G 77M 956G 1% /datadrive /dev/sdb1 16G 45M 15G 1% /mnt tmpfs 794M 0 794M 0% /run/user/1001
Arrange directory usage from top to bottom
To display the directory usage in order from the top, combine sort and head with the du command. Useful for discovering large directories.
du templates | sort -rn | head -20
The output results are output in descending order of directory capacity.

Specifying "/" for du and waiting for a while is convenient because you can see which directories are consuming space on the entire system.
How to check the capacity of the disk?
Use the df command to check the capacity of the disk.
Note that the du command is a command to check the directory capacity, and the df command is used to check the disk capacity.
