dir命令后可以接的完整参数dir 命令后可以接的完整参数# dir --help⽤法：dir [选项]... [⽂件]...List information about the FILEs (the current directory by default).Sort entries alphabetically if none of -cftuvSUX nor --sort.长选项必须⽤的参数在使⽤短选项时也是必须的。-a, --all 不隐藏任何以 . 字符开始的项⽬-A, --almost-all 列出除了 . 及 .. 以外的任何项⽬--author 和 -l 同时使⽤时列出每个⽂件的作者-b, --escape 以⼋进制溢出序列表⽰不可打印的字符--block-size=⼤⼩ 块以指定<⼤⼩>的字节为单位-B, --ignore-backups 不列出任何以 ~ 字符结束的项⽬-c 配合 -lt：根据 ctime 排序及显⽰ ctime (⽂件状态最后更改的时间)配合 -l：显⽰ ctime 但根据名称排序否则：根据 ctime 排序-C list entries by columns--color[=WHEN] control whether color is used to distinguish filetypes. WHEN may be `never', `always', or `auto'-d, --directory list directory entries instead of contents,and do not dereference symbolic links-D, --dired generate output designed for Emacs' dired mode-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 , 1K 234M 2G)--si likewise, but use powers of 1000 not 1024-H, --dereference-command-linefollow symbolic links listed on the command line--dereference-command-line-symlink-to-dirfollow each command line symbolic linkthat 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 使⽤较长格式列出信息-L, --dereference 当显⽰符号链接的⽂件信息时，显⽰符号链接所指⽰的对象⽽并⾮符号链接本⾝的信息-m 所有项⽬以逗号分隔，并填满整⾏⾏宽-n, --numeric-uid-gid like -l, but list numeric user and group IDs-N, --literal print raw entry names (don't controlcharacters specially)-o like -l, but do not list group information-p, --indicator-style=slashappend / indicator to directories-q, --hide-control-chars 以 ? 字符代替⽆法打印的字符--show-control-chars 直接显⽰⽆法打印的字符 (这是默认⽅式，除⾮调⽤的程序名称是“ls”⽽且是在终端机画⾯输出结果)-Q, --quote-name 将项⽬名称括上双引号--quoting-style=⽅式 使⽤指定的 quoting <⽅式>显⽰项⽬的名称：literal、locale、shell、shell-always、c、escape-r, --reverse 逆序排序-R, --recursive 递归列出所有⼦⽬录-s, --size 和 -l 同时使⽤时以块为单位列出每个⽂件的⼤⼩-S 根据⽂件⼤⼩排序--sort=WORD 以下是可选⽤的 WORD 和它们代表的相应选项：extension -X status -cnone -U time -tsize -S atime -utime -t access -uversion -v use -u--time=WORD 和 -l 同时使⽤时显⽰ WORD 所代表的时间⽽⾮修改时间：atime、access、use、ctime 或 status；加上--sort=time 选项时会以指定时间作为排序关键字--time-style=STYLE 和 -l 同时使⽤时根据 STYLE 代表的格式显⽰时间：full-iso、iso、locale、posix-iso、+FORMAT。FORMAT 即是“date”所⽤的时间格式；如果 FORMAT是 FORMAT1<新⾏>FORMAT2，FORMAT1 适⽤于较旧的⽂件⽽ FORMAT2 适⽤于较新的⽂件；如果 STYLE以“posix-”开头，则 STYLE 仅在 POSIX 语系之外⽣效。-t 根据修改时间排序-T, --tabsize=宽度 ⾃⾏指定 tab 的<宽度>，⽽⾮ 8 个字符-u with -lt: sort by, and show, access timewith -l:

show access time and sort by nameotherwise: sort by access time-U do not sort; list entries in directory combination with one_per_line format `-1',it will show files immediately and it has nomemory limitations.-v sort by version-w, --width=COLS ⾃⾏指定萤幕宽度⽽不使⽤⽬前的数值-x 逐⾏列出项⽬⽽不是逐栏列出-X 根据扩展名排序-1 每⾏只列出⼀个⽂件SELinux options:--lcontext Display security context. Enable -l. Lineswill probably be too wide for most displays.-Z, --context Display security context so it fits on mostdisplays. Displays only mode, user, group,security context and file name.--scontext Display only security context and file name.--help 显⽰此帮助信息并退出--version 输出版本信息并退出[⼤⼩]可以是以下的单位(单位前可加上整数)：kB 1000，K 1024，MB 1000000，M 1048576，还有 G、T、P、E、Z、Y。By default, color is not used to distinguish types of files. That isequivalent to using --color=none. Using the --color option without theoptional WHEN argument is equivalent to using --color=always. With--color=auto, color codes are output only if standard output is connectedto a terminal (tty). The environment variable LS_COLORS can influence thecolors, and can be set easily by the dircolors status is 0 if OK, 1 if minor problems, 2 if serious trouble.
