+.Sh NAME
+.Nm colorls
+.Nd list directory contents in color
+.Sh SYNOPSIS
+.Nm colorls
+.Op Fl ACFGLRTWacdfiloqrstu1
+.Op Ar file ...
+.Sh DESCRIPTION
+(Note: This man page describes the color version of the program. To
+minimize the differences from the original, the program is referred to
+as
+.Nm ls
+in this manual. The new option
+.Fl G
+is for color display.)
+.Pp
+For each operand that names a
+.Ar file
+of a type other than
+directory,
+.Nm ls
+displays its name as well as any requested,
+associated information.
+For each operand that names a
+.Ar file
+of type directory,
+.Nm ls
+displays the names of files contained
+within that directory, as well as any requested, associated
+information.
+.Pp
+If no operands are given, the contents of the current
+directory are displayed.
+If more than one operand is given,
+non-directory operands are displayed first; directory
+and non-directory operands are sorted separately and in
+lexicographical order.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl A
+List all entries except for
+.Ql \&.
+and
+.Ql \&.. .
+Always set for the super-user.
+.It Fl C
+Force multi-column output; this is the default when output is to a terminal.
+.It Fl F
+Display a slash (/) immediately after each pathname
+that is a directory, an asterisk (*) after each that is
+executable,
+an at sign (@) after each symbolic link,
+an equals sign (=) after each socket,
+a percent sign (%) after each whiteout,
+and a vertical bar (|) after each that is a
+.Tn FIFO .
+.It Fl G
+Use ANSI color sequences to distinguish file types. (See
+.Ev LSCOLORS
+below.) In addition to those mentioned above in
+.Fl F ,
+some extra attributes (setuid bit set, etc.) are also displayed.
+.It Fl L
+If argument is a symbolic link, list the file or directory the link references
+rather than the link itself.
+.It Fl R
+Recursively list subdirectories encountered.
+.It Fl T
+Display complete time information for the file, including
+month, day, hour, minute, second, and year.
+.It Fl W
+Display whiteouts when scanning directories. (UNIMPLEMENTED)
+.It Fl a
+Include directory entries whose names begin with a
+dot (.).
+.It Fl c
+Use time when file status was last changed for sorting or printing.
+.It Fl d
+Directories are listed as plain files (not searched recursively) and
+symbolic links in the argument list are not indirected through.
+.It Fl f
+Output is not sorted.
+.It Fl i
+For each file, print the file's file serial number (inode number).
+.It Fl k
+If the 's' option is specified, print the file size allocation in kilobytes,
+not blocks.
+.It Fl l
+(The lowercase letter ``ell.'') List in long format. (See below.)
+If the output is to a terminal, a total sum for all the file
+sizes is output on a line before the long listing.
+.It Fl o
+Include the file flags in a long
+.Pq Fl l
+output
+.It Fl q
+Force printing of non-graphic characters in file names as
+the character `?'; this is the default when output is to a terminal.
+.It Fl r
+Reverse the order of the sort to get reverse
+lexicographical order or the oldest entries first.
+.It Fl s
+Display the number of file system blocks actually used by each file, in units
+of 512 bytes, where partial units are rounded up to the next integer value.
+If the output is to a terminal, a total sum for all the file
+sizes is output on a line before the listing.
+.It Fl t
+Sort by time modified (most recently modified
+first) before sorting the operands by lexicographical
+order.
+.It Fl u
+Use time of last access,
+instead of last modification
+of the file for sorting
+.Pq Fl t
+or printing
+.Pq Fl l .
+.It Fl \&1
+(The numeric digit ``one.'') Force output to be
+one entry per line.
+This is the default when
+output is not to a terminal.
+.El
+.Pp
+The
+.Fl 1 ,
+.Fl C ,
+and
+.Fl l
+options all override each other; the last one specified determines
+the format used.
+.Pp
+The
+.Fl c ,
+and
+.Fl u
+options override each other; the last one specified determines
+the file time used.
+.Pp
+By default,
+.Nm ls
+lists one entry per line to standard
+output; the exceptions are to terminals or when the
+.Fl C
+option is specified.
+.Pp
+File information is displayed with one or more
+<blank>s separating the information associated with the
+.Fl i ,
+.Fl s ,
+and
+.Fl l
+options.
+.Ss The Long Format
+If the
+.Fl l
+option is given, the following information
+is displayed for each file:
+file mode,
+number of links, owner name, group name,
+number of bytes in the file, abbreviated
+month, day-of-month file was last modified,
+hour file last modified, minute file last
+modified, and the pathname.
+In addition, for each directory whose contents are displayed, the total
+number of 512-byte blocks used by the files in the directory is displayed
+on a line by itself immediately before the information for the files in the
+directory.
+.Pp
+If the owner or group names are not a known user or group name
+the numeric ID's are displayed.
+.Pp
+If the file is a character special or block special file,
+the major and minor device numbers for the file are displayed
+in the size field. If the file is a symbolic link the pathname of the
+linked-to file is preceded by
+.Dq \-> .
+.Pp
+The file mode printed under the -l option consists of the
+entry type, owner permissions, and group permissions.
+The entry type character describes the type of file, as
+follows:
+.Pp
+.Bl -tag -width 4n -offset indent -compact
+.It Sy b
+Block special file.
+.It Sy c
+Character special file.
+.It Sy d
+Directory.
+.It Sy l
+Symbolic link.
+.It Sy s
+Socket link.
+.It Sy p
+.Tn FIFO .
+.It Sy \-
+Regular file.
+.El
+.Pp
+The next three fields
+are three characters each:
+owner permissions,
+group permissions, and
+other permissions.
+Each field has three character positions:
+.Bl -enum -offset indent
+.It
+If
+.Sy r ,
+the file is readable; if
+.Sy \- ,
+it is not readable.
+.It
+If
+.Sy w ,
+the file is writable; if
+.Sy \- ,
+it is not writable.
+.It
+The first of the following that applies:
+.Bl -tag -width 4n -offset indent
+.It Sy S
+If in the owner permissions, the file is not executable and
+set-user-ID mode is set.
+If in the group permissions, the file is not executable
+and set-group-ID mode is set.
+.It Sy s
+If in the owner permissions, the file is executable
+and set-user-ID mode is set.
+If in the group permissions, the file is executable
+and setgroup-ID mode is set.
+.It Sy x
+The file is executable or the directory is
+searchable.
+.It Sy \-
+The file is neither readable, writeable, executable,
+nor set-user-ID nor set-group-ID mode, nor sticky. (See below.)
+.El
+.Pp
+These next two apply only to the third character in the last group
+(other permissions).
+.Bl -tag -width 4n -offset indent
+.It Sy T
+The sticky bit is set
+(mode
+.Li 1000 ) ,
+but not execute or search permission. (See
+.Xr chmod 1
+or
+.Xr sticky 8 . )
+.It Sy t
+The sticky bit is set (mode
+.Li 1000 ) ,
+and is searchable or executable.
+(See
+.Xr chmod 1
+or
+.Xr sticky 8 . )
+.El
+.El
+.Pp
+The
+.Nm ls
+utility exits 0 on success, and >0 if an error occurs.
+.Sh ENVIRONMENTAL VARIABLES
+The following environment variables affect the execution of
+.Nm ls :
+.Bl -tag -width BLOCKSIZE
+.It Ev BLOCKSIZE
+If the environmental variable
+.Ev BLOCKSIZE
+is set, the block counts
+(see
+.Fl s )
+will be displayed in units of that size block.
+.It COLUMNS
+If this variable contains a string representing a
+decimal integer, it is used as the
+column position width for displaying
+multiple-text-column output.
+The
+.Nm ls
+utility calculates how
+many pathname text columns to display
+based on the width provided.
+(See
+.Fl C . )
+.It Ev TZ
+The timezone to use when displaying dates.
+See
+.Xr environ 7
+for more information.
+.It LSCOLORS
+The value of this variable describes what color to use for which
+attribute when the color output
+.Pq Fl G
+is specified. This string is a concatenation of pairs of the format
+.Sy fb ,
+where
+.Sy f
+is the foreground color and
+.Sy b
+is the background color.
+.Pp
+The color designators are as follows:
+.Pp
+.Bl -tag -width 4n -offset indent -compact
+.It Sy 0
+black
+.It Sy 1
+red
+.It Sy 2
+green
+.It Sy 3
+yellow
+.It Sy 4
+blue
+.It Sy 5
+magenta
+.It Sy 6
+cyan
+.It Sy 7
+white
+.It Sy x
+default foreground or background
+.El
+.Pp
+(Note: the above are standard ANSI colors. The actual display may
+differ depending on the color capabilities of your terminal.)
+.Pp
+The order of the attributes are as follows:
+.Pp
+.Bl -enum -offset indent -compact
+.It
+directory
+.It
+symbolic link
+.It
+socket
+.It
+pipe
+.It
+executable
+.It
+block special
+.It
+character special
+.It
+executable with setuid bit set
+.It
+executable with setgid bit set
+.It
+directory writable to others, with sticky bit
+.It
+directory writable to others, without sticky bit
+.El
+.Pp
+The default is "4x5x2x3x1x464301060203", i.e., blue foreground and
+default background for regular directories, black foreground and red
+background for setuid executables, etc.
+.El
+.Sh COMPATIBILITY
+The group field is now automatically included in the long listing for
+files in order to be compatible with the
+.St -p1003.2
+specification.
+.Sh SEE ALSO
+.Xr chmod 1 ,
+.Xr symlink 7 ,
+.Xr sticky 8
+.Sh HISTORY
+An
+.Nm ls
+command appeared in
+.At v1 .
+.Sh STANDARDS
+The
+.Nm ls
+function is expected to be a superset of the
+.St -p1003.2
+specification.
