Usage: du [options] ... [File] ...
Or: du [options] ...--files0-from=f
Calculate the disk usage for each file, and the directory will take the total amount.
The long option must use parameters that are also required for short options.
-A,--all the disk usage of all files, not just the directory
--apparent-size displays surface dosage, not disk usage, although surface dosage is usually smaller, sometimes it becomes larger due to "holes", internal fragments, non-directly referenced blocks between sparse files.
-B,--block-size= size block with specified number of bytes
-B,--bytes equals--apparent-size--block-size=1
-C,--total display total information
-D,--dereference-args remove symbolic connections listed on the command line
--files0-from=f the file name that ends with NUL in the computed files F corresponds to the disk space occupied
If the value of F is "-", the file name is read from the standard input
-H equals--dereference-args (-D)
-H,--human-readable display dimensions in a more readable manner (e.g. 1K 234M 2G)
--si is similar to-H, but uses 1000 as the base instead of 1024 when calculating
-K equals--block-size=1k
-L,--count-links if it is a hard connection, calculate its dimensions multiple times
-M equals--block-size=1m
-L,--dereference find out the true destination of any symbolic link indication
-P,--no-dereference does not follow any symbolic link (default)
-0,--null each blank line as 0 bytes instead of line break
-S,--separate-dirs does not include the amount of sub-directories
-S,--summarize only calculates the total amount of each parameter in the command column separately
-X,--one-file-system skips directories on different file systems
-X,--exclude-from= file excludes files that match the pattern described in the specified file
--exclude=pattern exclude files that match the patterns described in pattern
--max-depth=n Show catalog totals (use calculation files with--all)
When n is the specified value, the calculation depth is n;
--max-depth=0 equals--summarize.
--time Displays the last modified time for all files in the directory or subdirectory
--time=word Displays the WORD time, not the modified time:
Atime,access,use,ctime or Status
The--time-style= style displays the time in the specified style (the style interpretation rule is the same as the "date" command):
Full-iso,long-iso,iso,+format
--HELP Display this help message and exit
--version display version information and exit
[Size] can be the following unit (the unit is preceded by an integer):
KB 1000,k 1024,mb 1000000,m 1048576, also G, T, P, E, Z, Y.

(2) Ubuntu view disk space size command df-h DF command is a Linux system to view the file system as a disk partition, you can add parameters to view the disk remaining space information, command format: DF-HL display format: File system capacity has been used to use the% mount point Filesystem Size used Avail use% mounted on/dev/hda2 45G 19G 24G 44%//dev/hda1 494
Df-h
The DF command is a Linux system that views the file system as a disk partition, which can be added with parameters to view the disk's remaining space information, command format:
Df-hl
The display format is:
File system capacity has been used with available% mount points
Filesystem Size used Avail use% mounted on
/dev/hda2 45G 19G 24G 44%/
/DEV/HDA1 494M 19M 450M 4%/boot
/dev/hda6 4.9G 2.2G 2.5G 47%/Home
/dev/hda5 9.7G 2.9G 6.4G 31%/opt
None 1009M 0 1009M 0%/dev/shm
/dev/hda3 9.7G 7.2G 2.1G 78%/usr/local
/DEV/HDB2 75G 75G 0 100%/
/DEV/HDB2 75G 75G 0 100%/
With the above output as an example, the meaning of the expression is:
The second hard drive interface (b), the second partition (2), the capacity is 75G, with 75G, usable is 0, so the utilization is 100%, is mounted to the root partition directory (/).
The following is an explanation of the relevant commands:
DF-HL Viewing disk space remaining
Df-h viewing the partition size for each root path
Du-sh [directory Name] Returns the size of the directory
DU-SM [Folder] Returns the total number of M in this folder
More functions you can enter the command to view:
DF--help
Du--help
