du - disk 사용량 확인

du

폴더, 파일의 디스크 사용량을 알아내는 명령어로, 내가 자주 사용하는 옵션은 아래와 같다.

DESCRIPTION Summarize disk usage of each FILE, recursively for directories. Mandatory arguments to long options are mandatory for short options too. [OPTION] -h, --human-readable print sizes in human readable format (e.g., 1K 234M 2G) -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 -X, --exclude-from=FILE exclude files that match any pattern in FILE --exclude=PATTERN exclude files that match PATTERN

사용하면 아래와 같이 각 폴더별 용량을 알 수 있다.

[00:55:43]~/work>du -h -d1 15M ./wordpress 12K ./test 16K ./torrent 8.2M ./ipban 32K ./XBMC 17M ./uthline 14M ./4d3 12M ./geoip 64M .

du -- help

그외의 옵션은 아래를 참고해주세요

du --help 사용법: du [옵션]... [파일]... 또는: du [옵션]... --files0-from=F 지정한 각 파일의 디스크 사용량을 요약함, 하위 디렉토리에 대해서도. 긴 옵션에서 꼭 필요한 인수는 짧은 옵션에도 꼭 필요합니다. -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 --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) --si like -h, but use powers of 1000 not 1024 -k like --block-size=1K -l, --count-links count sizes many times if hard linked -m like --block-size=1M -L, --dereference dereference all symbolic links -P, --no-dereference don't follow any symbolic links (this is the default) -0, --null end each output line with 0 byte rather than newline -S, --separate-dirs do not include size of subdirectories -s, --summarize display only a total for each argument -x, --one-file-system skip directories on different file systems -X, --exclude-from=FILE exclude files that match any pattern in FILE --exclude=PATTERN exclude files that match PATTERN -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 --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 STYLE: full-iso, long-iso, iso, +FORMAT FORMAT is interpreted like `date' --help 이 도움말을 표시하고 끝냅니다 --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 may be (or may be an integer optionally followed by) one of following: KB 1000, K 1024, MB 1000*1000, M 1024*1024, and so on for G, T, P, E, Z, Y.
