• ls 参数


    [root@VFSD upload_folder]# ls --help
    Usage: ls [OPTION]... [FILE]...
    List information about the FILEs (the current directory by default).
    Sort entries alphabetically if none of -cftuvSUX nor --sort is specified.

    Mandatory arguments to long options are mandatory for short options too.
    -a, --all do not ignore entries starting with .
    -A, --almost-all do not list implied . and ..
    --author with -l, print the author of each file
    -b, --escape print C-style escapes for nongraphic characters
    --block-size=SIZE scale sizes by SIZE before printing them; e.g.,
    '--block-size=M' prints sizes in units of
    1,048,576 bytes; see SIZE format below
    -B, --ignore-backups do not list implied entries ending with ~
    -c with -lt: sort by, and show, ctime (time of last
    modification of file status information);
    with -l: show ctime and sort by name;
    otherwise: sort by ctime, newest first
    -C list entries by columns
    --color[=WHEN] colorize the output; WHEN can be 'never', 'auto',
    or 'always' (the default); more info below
    -d, --directory list directories themselves, not their contents
    -D, --dired generate output designed for Emacs' dired mode
    -f do not sort, enable -aU, disable -ls --color
    -F, --classify append indicator (one of */=>@|) to entries
    --file-type likewise, except do not append '*'
    --format=WORD across -x, commas -m, horizontal -x, long -l,
    single-column -1, verbose -l, vertical -C
    --full-time like -l --time-style=full-iso
    -g like -l, but do not list owner
    --group-directories-first
    group directories before files;
    can be augmented with a --sort option, but any
    use of --sort=none (-U) disables grouping
    -G, --no-group in a long listing, don't print group names
    -h, --human-readable with -l, print sizes in human readable format
    (e.g., 1K 234M 2G)
    --si likewise, but use powers of 1000 not 1024
    -H, --dereference-command-line
    follow symbolic links listed on the command line
    --dereference-command-line-symlink-to-dir
    follow each command line symbolic link
    that points to a directory
    --hide=PATTERN do not list implied entries matching shell PATTERN
    (overridden by -a or -A)
    --indicator-style=WORD append indicator with style WORD to entry names:
    none (default), slash (-p),
    file-type (--file-type), classify (-F)
    -i, --inode print the index number of each file
    -I, --ignore=PATTERN do not list implied entries matching shell PATTERN
    -k, --kibibytes default to 1024-byte blocks for disk usage
    -l use a long listing format
    -L, --dereference when showing file information for a symbolic
    link, show information for the file the link
    references rather than for the link itself
    -m fill width with a comma separated list of entries
    -n, --numeric-uid-gid like -l, but list numeric user and group IDs
    -N, --literal print raw entry names (don't treat e.g. control
    characters specially)
    -o like -l, but do not list group information
    -p, --indicator-style=slash
    append / indicator to directories
    -q, --hide-control-chars print ? instead of nongraphic characters
    --show-control-chars show nongraphic characters as-is (the default,
    unless program is 'ls' and output is a terminal)
    -Q, --quote-name enclose entry names in double quotes
    --quoting-style=WORD use quoting style WORD for entry names:
    literal, locale, shell, shell-always, c, escape
    -r, --reverse reverse order while sorting
    -R, --recursive list subdirectories recursively
    -s, --size print the allocated size of each file, in blocks
    -S sort by file size
    --sort=WORD sort by WORD instead of name: none (-U), size (-S),
    time (-t), version (-v), extension (-X)
    --time=WORD with -l, show time as WORD instead of default
    modification time: atime or access or use (-u)
    ctime or status (-c); also use specified time
    as sort key if --sort=time
    --time-style=STYLE with -l, show times using style STYLE:
    full-iso, long-iso, iso, locale, or +FORMAT;
    FORMAT is interpreted like in 'date'; if FORMAT
    is FORMAT1<newline>FORMAT2, then FORMAT1 applies
    to non-recent files and FORMAT2 to recent files;
    if STYLE is prefixed with 'posix-', STYLE
    takes effect only outside the POSIX locale
    -t sort by modification time, newest first
    -T, --tabsize=COLS assume tab stops at each COLS instead of 8
    -u with -lt: sort by, and show, access time;
    with -l: show access time and sort by name;
    otherwise: sort by access time
    -U do not sort; list entries in directory order
    -v natural sort of (version) numbers within text
    -w, --width=COLS assume screen width instead of current value
    -x list entries by lines instead of by columns
    -X sort alphabetically by entry extension
    -1 list one file per line

    SELinux options:

    --lcontext Display security context. Enable -l. Lines
    will probably be too wide for most displays.
    -Z, --context Display security context so it fits on most
    displays. Displays only mode, user, group,
    security context and file name.
    --scontext Display only security context and file name.
    --help display this help and exit
    --version output version information and exit

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

    Using color to distinguish file types is disabled both by default and
    with --color=never. With --color=auto, ls emits color codes only when
    standard output is connected to a terminal. The LS_COLORS environment
    variable can change the settings. Use the dircolors command to set it.

    Exit status:
    0 if OK,
    1 if minor problems (e.g., cannot access subdirectory),
    2 if serious trouble (e.g., cannot access command-line argument).
