dir(1) - list directory contents
dir [OPTION]... [FILE]...
-a, --all
       do not ignore entries starting with .
-A, --almost-all
       do not list implied . and ..
       with -l, print the author of each file
-b, --escape
       print C-style escapes for nongraphic characters
       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
       colorize the output.  WHEN defaults to `always' or can be `never' or `auto'.  More info below
-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 -ls --color
-F, --classify
       append indicator (one of */=>@|) to entries
       likewise, except do not append `*'
       across -x, commas -m, horizontal -x, long -l, single-column -1, verbose -l, vertical -C
       like -l --time-style=full-iso
-g     like -l, but do not list owner
       group directories before files.

              augment 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
       follow each command line symbolic link that points to a directory
       do not list implied entries matching shell PATTERN (overridden by -a or -A)
       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     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 non graphic characters as-is (default unless program is `ls' and output is a terminal)
-Q, --quote-name
       enclose entry names in double quotes
       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 by WORD instead of name: none -U, extension -X, size -S, time -t, version -v
       with -l, show time as WORD instead of modification time: atime -u, access -u, use -u, ctime -c, or
       status -c; use specified time as sort key if --sort=time
       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, 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
-Z, --context
       print any SELinux security context of each file
-1     list one file per line
--help display this help and exit
       output version information and exit
