Linux Statistics folder footprint size--DU command basic usage

command-line environment to know the Linux system in a folder and its containing the actual amount of space occupied by the file, the Linux command du can be very good to meet the requirements.

I do not write all of the other uses, I think it will use the most, directly on:

$ du -sh . /* 118M.    /chemi4.0k    ./collectionframework32m.    /C Programming version fourth. Rectification. Scan version pdf7.7m    ./jsfppt360m.    / mooc34m    ./mvnt1.4g.    /reference251m    ./Compression Pack 20K    ./interview. ODT

The first column of output is the volume occupied by the file or folder, and the right side is the folder

Here are the options:

-S is to calculate the total space occupied by each directory, and no words will recursively list a lot of useless information;

-H very good understanding, is to choose the right unit, above some with M, some with G, so it is clear, here du's usage is this, detailed other options can refer to the man page.

The wildcard character is used in the parameter to list all files or folders in the current directory, otherwise only the total size of the current directory is listed.

In addition, you may also think of the LS command, the general usage is this:

$LS-Alhtotal2.0MDrwxr-xr-xPrompt prompt4.0K December213:44. drwxr-xr-x6 root root4.0K July2316:29..

Here LS is the option of everyone should know (-a display all files and folders, including the beginning of the;-l lists details such as the size of the occupied space, the user and so on;-H displays the amount of space in the appropriate units, such as using M or g), The size of the file is 4.0K, obviously it contains more than the file.
