-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

-C list entries by columns

control whether color is used to distinguish file types. WHEN
may be `never', `always', or `auto'

-d, --directory
list directory entries instead of contents, and do not derefer-
ence 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 `*'

-G, --no-group
in a long listing, don't print group names

-h, --human-readable

--si likewise, but use powers of 1000 not 1024

-H, --dereference-command-line

follow each command line symbolic link that points to a direc-

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 informa-
tion for the file the link references rather than for the link

-m fill width with a comma separated list of entries

-n, --numeric-uid-gid

-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 FORMAT1FORMAT2, 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 otherwise: sort by access time

-U do not sort; list entries in directory order
