查看一个目录一共占用了多大空间 : 进入那个目录 ,运行 du -sh
或者直接 du -sh 绝对路径名
[crifan@localhost tmp]$ du –help
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.
-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 use SIZE-byte blocks
-b, –bytes equivalent to `–apparent-size –block-size=1′
-c, –total produce a grand total
-D, –dereference-args dereference FILEs that are symbolic links
–files0-from=F summarize disk usage of the NUL-terminated file
names specified in file F
-H like –si, but also evokes a warning; will soon
change to be 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 FILE, –exclude-from=FILE Exclude files that match any pattern in FILE.
–exclude=PATTERN Exclude files that match PATTERN.
–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
–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 display this help and exit
–version output version information and exit
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.
