1.1 the df command df can view the first-level folder size, usage ratio, file system and its mount point, but there is nothing you can do with files. Du can view the size of files and folders.

The file system that can be used to view partitions

Df-T

The df command displays the free space and use cases of all current file systems

Df-h

1.2 du command / / View the usage of files in the system df-h / / View the space occupied by each file and directory under the current directory du-sh * / method 1: change to the directory to be deleted, delete all files in the directory rm-f * / method 2: delete all files under the logs folder Without deleting the folder itself, rm-rf log/*du: query the disk usage space of a file or folder

Quote paragraph if there are a lot of files and folders in the current directory, use the command without the parameter du to cycle through the space used by all files and folders. This is disadvantageous to see which place is too large, so you have to specify the number of layers in the deep directory, the parameter:-max-depth=, this is a very useful parameter!

As follows, pay attention to the use of "*" to get the size of the file space.

Reminder: for FreeBSD, which has always been more complex than linux, its du command specifies the number of layers in the deep directory is simpler than linux, which is-d. Du-h-max-depth=1 / home

What are the similarities and differences between the following command and the above command?

Answer: du-h-max-depth=1 / home lists only all the first-level directory file sizes under the home directory

Du-h-max-depth=1 / home/* lists the first-level directory file sizes for all first-level directories under home.

Du-h-max-depth=1 / home/*

Linux:ls views file sizes in K, M, G units

Note the use of the man command. Press the "Q" key to exit the man query.
