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 subtreeDu/home/linux This displays 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 unitsDu-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 megabytesDu-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 gigabytesDu-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 representation with the human form of K, M, G display
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 The summary meaning that only a summarized value is listed du-h--max-depth=0 user--max-depth=n means only deep into the nth-level directory, which is set to 0, meaning that it does not 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) represents information for each directory that is listed, without wrapping, but directly outputting the information for the next directory.
10> only shows all disk usage for one directory treeDu-s/home/linux
11> View each folder size: Du-h--max-depth=1
