du 命令
...
在 Linux 中,你可以使用 du(Disk Usage)命令来查看当前目录下所有内容占用的磁盘大小。以下是一些常用的命令示例:
- 查看当前目录下所有文件和文件夹的大小
du -h --max-depth=1
• -h:以人类可读的方式显示大小(例如 KB、MB、GB)。
• --max-depth=1:只显示当前目录下的文件和文件夹的大小,而不递归深入子目录。
2. 查看当前目录的总大小
du -sh
• -s:只显示总计大小。
• -h:以人类可读的方式显示大小。
3. 查看当前目录下最大的文件或文件夹
du -h --max-depth=1 | sort -hr
• sort -hr:按大小从大到小排序(-h 表示支持人类可读格式,-r 表示逆序排列)。
4. 查看某个特定文件或文件夹的大小
du -h /path/to/file_or_folder
通过这些命令,你可以轻松了解当前目录下文件和文件夹的磁盘占用情况。希望对你有帮助!
du --help
Usage: du [OPTION]... [FILE]...
or: du [OPTION]... --files0-from=F
Summarize disk usage of the set of FILEs, recursively for directories.
Mandatory arguments to long options are mandatory for short options too.
-0, --null end each output line with NUL, not 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
--help display this help and exit
--version output version information and exit
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).
The SIZE argument is an integer and optional unit (example: 10K is 10*1024).
Units are K,M,G,T,P,E,Z,Y (powers of 1024) or KB,MB,... (powers of 1000).

常见用法
显示某文件大小
# 显示某文件大小
du -sh xxxfile
20M xxxfile
排除特定目录
在使用 du -sh 命令时,如果想要排除某个特定的目录,可以结合 --exclude 选项来实现。以下是具体的用法:
注意:macos 下 du 命令不支持改参数
du -sh --exclude=DIR --exclude=folder2 --exclude=folder3
# or
du -sh --exclude=".*" # 排除所有隐藏文件和隐藏目录
- DIR 是你想要排除的目录名称。
- du -sh 将会计算当前目录的总大小,但会忽略掉 --exclude 参数中指定的目录。
- 如果需要排除多个目录,可以多次使用 --exclude:
macos 显示某代码库大小
macOS 的 du 命令功能相对有限,-I mask 并不能像 Linux 的 --exclude 那样灵活。
-I mask 选项允许你指定一个通配符模式(mask),以忽略符合该模式的文件或目录。例如:
du -sh .
# or
du -sh .git
# or 排除 .git 目录
du -sh -I ".git"
