du [-ABCDHHKLMSSX] [-l < Sign connection >][-x < files >][--block-size][--exclude=< directories or files;] [--max-depth=< directory Layer >][--help][--version][directory or file]

Common parameters:

-A or-all displays disk usage for each specified file, or displays the respective disk usage for each file in the directory.

-B or-bytes displays the directory or file size, in bytes.

-C or –total displays the sum of all directories or files in addition to the size of the directory or file.

-D or –dereference-args displays the source file size for the specified symbolic connection.

-H or –human-readable in k,m,g to improve the readability of the information.

-H or –si is the same as the-h parameter, but K,m,g is converted to 1000 units instead of 1024.

-K or –kilobytes in bytes units.

-L or –count-links repeatedly compute the files for the hardware connection.

-l< symbol connection > or –dereference< symbol connection > Display option the source file size of the symbol connection specified.

-M or –megabytes in 1MB units.

-S or –summarize displays only totals, that is, the size of the current directory.

-S or –separate-dirs displays the size of each directory without the size of its subdirectories.

-X or –one-file-xystem the file system at the beginning of the processing, if any other different file system directories are skipped.

-x< file > or –exclude-from=< file > in < file > specify directory or file.

–exclude=< directory or File > skip the specified directory or file.

–max-depth=< the number of directory layers > directories that exceed the specified number of layers is ignored.

Help Display Help.

–version Displays version information.

1> to display disk usage for a directory tree and every subtree

Du/home/linux

This shows the number of disk blocks in the/home/linux directory and each of its subdirectories.

2> to display the disk usage of a tree and each of its subtrees in 1024-byte units

Du-k/home/linux

This shows the number of 1024-byte disk blocks in the/home/linux directory and each of its subdirectories.

3> displays the disk usage of a directory tree and each of its subtrees in megabytes

Du-m/home/linux

This shows the number of MB disk blocks in the/home/linux directory and each of its subdirectories.

4> displays the disk usage of one directory tree and each subtree in gigabytes

Du-g/home/linux

This displays the number of GB disk blocks in the/home/linux directory and each of its subdirectories.

5> View the size of all directories and subdirectories under the current directory:

Du-h.

“.” Represents the current directory. can also be replaced by a clear path

-h means to display the human form of K, M and G

6> View the size of the user directory under the current directory, and do not want to see other directories and their subdirectories:

Du-sh User

-S means that a summary value is listed only

Du-h--max-depth=0 User

--max-depth=n means that only deep into the nth-level directory, where set to 0, means not to go deep into subdirectories.

7> lists the size of all directories and files under the user directory and its subdirectories:

Du-ah User

-a means including directories and files

8> lists the size of the directory in the current directory that does not include the XYZ string:

Du-h--exclude= ' *xyz* '

9> want to get more information about the user directory and the size of subdirectories on one screen:

du-0h User

0 (bar 0) indicates the information for each directory listed, not wrapping, but outputting the information of the next directory directly.

10> only shows all disk usage for one directory tree

Du-s/home/linux

11> View each folder size: Du-h--max-depth=1
