ls 命令可以说是Linux下最常用的命令之一。它有众多的选项，其中有很多是很有用的，你是否熟悉呢？下面列出了 ls 命令的绝大多数选项。

-a 列出目录下的所有文件，包括以 . 开头的隐含文件。
-b 把文件名中不可输出的字符用反斜杠加字符编号(就象在C语言里一样)的形式列出。
-c 输出文件的 i 节点的修改时间，并以此排序。
-d 将目录象文件一样显示，而不是显示其下的文件。
-e 输出时间的全部信息，而不是输出简略信息。
-f -U 对输出的文件不排序。
-g 无用。
-i 输出文件的 i 节点的索引信息。
-k 以 k 字节的形式表示文件的大小。
-l 列出文件的详细信息。
-m 横向输出文件名，并以“，”作分格符。
-n 用数字的 UID,GID 代替名称。
-o 显示文件的除组信息外的详细信息。
-p -F 在每个文件名后附上一个字符以说明该文件的类型，“*”表示可执行的普通
文件；“/”表示目录；“@”表示符号链接；“|”表示FIFOs；“=”表示套
接字(sockets)。
-q 用?代替不可输出的字符。
-r 对目录反向排序。
-s 在每个文件名后输出该文件的大小。
-t 以时间排序。
-u 以文件上次被访问的时间排序。
-x 按列输出，横向排序。
-A 显示除 “.”和“..”外的所有文件。
-B 不输出以 “~”结尾的备份文件。
-C 按列输出，纵向排序。
-G 输出文件的组的信息。
-L 列出链接文件名而不是链接到的文件。
-N 不限制文件长度。
-Q 把输出的文件名用双引号括起来。
-R 列出所有子目录下的文件。
-S 以文件大小排序。
-X 以文件的扩展名(最后一个 . 后的字符)排序。
-1 一行只输出一个文件。
--color=no 不显示彩色文件名
--help 在标准输出上显示帮助信息。
--version 在标准输出上输出版本信息并退出。

NAME
       ls - list directory contents

SYNOPSIS
       ls [OPTION]... [FILE]...

DESCRIPTION
       List information about the FILEs (the current directory by default). Sort entries alphabeti-
       cally if none of -cftuvSUX nor --sort.

       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, --ignore-backups
              do not list implied entries ending with ~

       -c     with -lt: sort by, and show, ctime (time of last modification of file status informa-
              tion) with -l: show ctime and sort by name otherwise: sort by ctime

       -C     list entries by columns

       --color[=WHEN]
              control whether color is used to distinguish file types. WHEN may be ‘never’, ‘always’,

              list directory entries instead of contents, and do not dereference symbolic links

       -D, --dired

       -f     do not sort, enable -aU, disable -lst

       -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

       -G, --no-group
              like -l, but do not list group

       -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
              with -l, print the index number of each file

       -I, --ignore=PATTERN
              do not list implied entries matching shell PATTERN

       -k     like --block-size=1K

       -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 non graphic characters

       --show-control-chars
              show non graphic characters as-is (default unless program is ‘ls’ and output is a termi-
              nal)

       -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
              with -l, print size of each file, in blocks

       -S     sort by file size

       --sort=WORD
              extension -X, none -U, size -S, time -t, version -v, status -c, time -t, atime -u,
              access -u, use -u

       --time=WORD
              with -l, show time as WORD instead of modification time: atime, access, use, ctime or
              status; 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, +FORMAT. FORMAT
              is interpreted like ‘date’; if FORMAT is FORMAT1<newline>FORMAT2, 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

       -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 oth-
              erwise: sort by access time

       -U     do not sort; list entries in directory order

       -v     sort by version

       -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 dis-
              plays.

       -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 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.

       By default, color is not used to distinguish types of files. That is equivalent to using
       --color=none. Using the --color option without the optional WHEN argument is equivalent to
       using --color=always.   With --color=auto, color codes are output only if standard output is
       connected to a terminal (tty). The environment variable LS_COLORS can influence the colors,
       and can be set easily by the dircolors command.

       Exit status is 0 if OK, 1 if minor problems, 2 if serious trouble.
