Linux Command du, linuxdu

Linux Command du, linuxdu

The du command is one of the common commands for system O & M. Its purpose is to count the usage of file directories.

-A: displays the size of all files and directories recursively.

-- Apparent-size: displays the file and directory sizes, rather than disk usage.

-B, -- block-size = 'SIZE' indicates the number of blocks. The SIZE in quotation marks indicates the system block size.

-B displays the object size in byte mode, which is equivalent to -- apparent-size -- block-size = 1

-C: total number of surfaces and total number of Surfaces

-D computing does not contain linked files

-H is similar to -- si calculates the disk usage of files and directories in units of 1000

-H human readable mode (K, M, G)

-- Si replaces the conversion unit of 1000 with 1024

-K is similar to -- block-size = 1 k to specify the block size as 1 k and calculate the file directory size.

-L, -- count-links multiple computation if hard link is included

-M is similar to -- block-size = 1 MB. Specify the block size as 1 MB and calculate the file directory size.

-L, -- dereference and-D parameters are different, ignoring all linked objects (files, directories)

-P, -- no-dereference default parameter, no

-0: use 0 bytes to replace line breaks

-S, -- separate-dirs does not contain the subdirectory size

-S, -- summarize only displays the total size of each object in the current directory

-X, -- one-file-system skips directories on different file systems.

-X file, -- exclude-from = FILE does not contain matched objects. The FILE here is the FILE object specified by the user.

-- Exclude = PATTERN

-- Max-depth = displays directory-Level depth -- max-depth = 0 equals to -- summarize

-- Time: displays the last modification time of the file or subdirectory in the directory.

-- Time = WORD: display time with keywords WORD, including atime, access, use, ctime, status

-- Time-style = STYLE: Adjust the display time FORMAT. The FORMAT includes full-iso, long-iso, iso, and + FORMAT (the FORMAT is from the date command)

-- Version

 

SIZE contains kB 1000, K 1024, MB 1000*1000, M 1024*1024, and G, T, P, E, Z, Y, etc.

PATTERN is a shell expression, not a regular expression.

Common parameters:

Display All directory files in human readable form. This recursively displays all objects.

Du-ah

Displays sub-directories recursively. Only the total size of files and directories at the current level is counted.

Du-sh can also be replaced by du -- max-depth = 0-h

Display size in the specified unit

Du-B | du-k | du-m
