    查看磁盘: df -h

    df --help
    Usage: df [OPTION]... [FILE]...
    Show information about the file system on which each FILE resides,
    or all file systems by default.

    Mandatory arguments to long options are mandatory for short options too.
    -a, --all include dummy file systems
    -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.
    --total produce a grand total
    -h, --human-readable print sizes in human readable format (e.g., 1K 234M 2G)
    -H, --si likewise, but use powers of 1000 not 1024
    -i, --inodes list inode information instead of block usage
    -k like --block-size=1K
    -l, --local limit listing to local file systems
    --no-sync do not invoke sync before getting usage info (default)
    --output[=FIELD_LIST] use the output format defined by FIELD_LIST,
    or print all fields if FIELD_LIST is omitted.
    -P, --portability use the POSIX output format
    --sync invoke sync before getting usage info
    -t, --type=TYPE limit listing to file systems of type TYPE
    -T, --print-type print file system type
    -x, --exclude-type=TYPE limit listing to file systems not of type TYPE
    -v (ignored)
    --help display this help and exit
    --version output version information and exit

    查看当前目录: du -sh

    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.
    -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)
    -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 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 STYLE:
    full-iso, long-iso, iso, +FORMAT
    FORMAT is interpreted like '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

    linux查看文件大小

    du -sh sg_gvdeal_tmp.sql
    18M sg_gvdeal_tmp.sql
