Linux du 명령어 ( 디렉토리 용량 확인 )

du 명령어에 대해 정리합니다.

 

 

[cloud@ynkim 2020]$ ls
08 09 10 11 12

1. 해당 하위 디렉토리의 총용량을 GB 로 확인

   [cloud@ynkim 2020]$ du -sh
   51G .

2. 해당 디렉토리의 총용량을 MB로 확인

   [cloud@ynkim 2020]$ du -sm
   51915 .

3. 해당 디렉토리의 총용량을 KB 로 확인

   [cloud@ynkim 2020]$ du -sk
   53160696

4. 디렉토리별 용량 확인 ( GB 단위로 확인하기 )

   [cloud@ynkim 2020]$ du -sh ./*
   16G ./08
   12G ./09

   3G ./106G ./111G ./12

5. 특정 디렉토리만 용량을 알고 싶을 경우

   [cloud@ynkim 2020]$ du -sh ./08
   16G ./08

이정도만 알면 특별히 사용하는데 문제 없을듯 합니다.

 

 

du 명령어 option 정보

 

Usage: du [OPTION]... [FILE]...
or: du [OPTION]... --files0-from=F
Summarize disk usage of each FILE, recursively for directories.

Mandatory arguments to long options are mandatory for short options too.
-0, --null end each output line with 0 byte rather than newline
-a, --all write counts for all files, not just directories
--apparent-size print apparent sizes, rather than disk usage; although
the apparent size is usually smaller, it may be
larger due to holes in ('sparse') files, internal
fragmentation, indirect blocks, and the like
-B, --block-size=SIZE scale sizes by SIZE before printing them; e.g.,
'-BM' prints sizes in units of 1,048,576 bytes;
see SIZE format below
-b, --bytes equivalent to '--apparent-size --block-size=1'
-c, --total produce a grand total
-D, --dereference-args dereference only symlinks that are listed on the
command line
-d, --max-depth=N print the total for a directory (or file, with --all)
only if it is N or fewer levels below the command
line argument; --max-depth=0 is the same as
--summarize
--files0-from=F summarize disk usage of the
NUL-terminated file names specified in file F;
if F is -, then read names from standard input
-H equivalent to --dereference-args (-D)
-h, --human-readable print sizes in human readable format (e.g., 1K 234M 2G)
--inodes list inode usage information instead of block usage
-k like --block-size=1K
-L, --dereference dereference all symbolic links
-l, --count-links count sizes many times if hard linked
-m like --block-size=1M
-P, --no-dereference don't follow any symbolic links (this is the default)
-S, --separate-dirs for directories do not include size of subdirectories
--si like -h, but use powers of 1000 not 1024
-s, --summarize display only a total for each argument
-t, --threshold=SIZE exclude entries smaller than SIZE if positive,
or entries greater than SIZE if negative
--time show time of the last modification of any file in the
directory, or any of its subdirectories
--time=WORD show time as WORD instead of modification time:
atime, access, use, ctime or status
--time-style=STYLE show times using STYLE, which can be:
full-iso, long-iso, iso, or +FORMAT;
FORMAT is interpreted like in 'date'
-X, --exclude-from=FILE exclude files that match any pattern in FILE
--exclude=PATTERN exclude files that match PATTERN
-x, --one-file-system skip directories on different file systems

--version 버전 정보를 출력하고 끝냅니다

Display values are in units of the first available SIZE from --block-size,
and the DU_BLOCK_SIZE, BLOCK_SIZE and BLOCKSIZE environment variables.
Otherwise, units default to 1024 bytes (or 512 if POSIXLY_CORRECT is set).

SIZE is an integer and optional unit (example: 10M is 1010241024). Units
are K, M, G, T, P, E, Z, Y (powers of 1024) or KB, MB, ... (powers of 1000).
