DIR_COLORS (5) | File formats and conventions | Unix Manual Pages

DESCRIPTION

The program ls(1) uses the environment variable LS_COLORS to determine the colors in which the filenames are to be displayed. This environment variable is usually set by a command like

eval ‘dircolors some_path/dir_colors‘

found in a system default shell initialization file, like /etc/profile or /etc/csh.cshrc. (See also dircolors(1).) Usually, the file used here is /etc/DIR_COLORS and can be overridden by a .dir_colors file in one’s home directory.

This configuration file consists of several statements, one per line. Anything right of a hash mark (#) is treated as a comment, if the hash mark is at the beginning of a line or is preceded by at least one whitespace. Blank lines are ignored.

The global section of the file consists of any statement before the first TERM statement. Any statement in the global section of the file is considered valid for all terminal types. Following the global section is one or more terminal-specific sections, preceded by one or more TERM statements which specify the terminal types (as given by the TERM environment variable) the following declarations apply to. It is always possible to override a global declaration by a subsequent terminal-specific one.

The following statements are recognized; case is insignificant:

TERM terminal-type
	Starts a terminal-specific section and specifies which terminal it applies to. Multiple TERM statements can be used to create a section which applies for several terminal types.
COLOR yes\|all\|no\|none\|tty
	(Slackware only; ignored by GNU dircolors(1).) Specifies that colorization should always be enabled (yes or all), never enabled (no or none), or enabled only if the output is a terminal (tty). The default is no.
EIGHTBIT yes\|no
	(Slackware only; ignored by GNU dircolors(1).) Specifies that eight-bit ISO 8859 characters should be enabled by default. For compatibility reasons, this can also be specified as 1 for yes or 0 for no. The default is no.
OPTIONS options
	(Slackware only; ignored by GNU dircolors(1).) Adds command line options to the default ls command line. The options can be any valid ls command line options, and should include the leading minus sign. Please note that dircolors does not verify the validity of these options.
NORMAL color-sequence
	Specifies the color used for normal (non-filename) text.
FILE color-sequence
	Specifies the color used for a regular file.
DIR color-sequence
	Specifies the color used for directories.
LINK color-sequence
	Specifies the color used for a symbolic link.
ORPHAN color-sequence
	Specifies the color used for an orphaned symbolic link (one which points to a nonexistent file). If this is unspecified, ls will use the LINK color instead.
MISSING color-sequence
	Specifies the color used for a missing file (a nonexistent file which nevertheless has a symbolic link pointing to it). If this is unspecified, ls will use the FILE color instead.
FIFO color-sequence
	Specifies the color used for a FIFO (named pipe).
SOCK color-sequence
	Specifies the color used for a socket.
DOOR color-sequence
	(Supported since file-utils 4.1) Specifies the color used for a door (Solaris 2.5 and later).
BLK color-sequence
	Specifies the color used for a block device special file.
CHR color-sequence
	Specifies the color used for a character device special file.
EXEC color-sequence
	Specifies the color used for a file with the executable attribute set.
LEFTCODE color-sequence
	Specifies the "left code" for non-ISO 6429 terminals (see below).
RIGHTCODE color-sequence
	Specifies the "right code" for non-ISO 6429 terminals (see below).
ENDCODE color-sequence
	Specifies the "end code" for non-ISO 6429 terminals (see below).
*extension color-sequence
	Specifies the color used for any file that ends in extension.
.extension color-sequence
	Same as .extension. Specifies the color used for any file that ends in .extension. Note that the period is included in the extension, which makes it impossible to specify an extension not starting with a period, such as ~ for emacs* backup files. This form should be considered obsolete.

"ISO 6429 (ANSI) COLOR SEQUENCES"

Most color-capable ASCII terminals today use ISO 6429 (ANSI) color sequences, and many common terminals without color capability, including xterm and the widely used and cloned DEC VT100, will recognize ISO 6429 color codes and harmlessly eliminate them from the output or emulate them. ls uses ISO 6429 codes by default, assuming colorization is enabled.

ISO 6429 color sequences are composed of sequences of numbers separated by semicolons. The most common codes are:

0to restore default color
1for brighter colors
4for underlined text
5for flashing text
30for black foreground
31for red foreground
32for green foreground
33for yellow (or brown) foreground
34for blue foreground
35for purple foreground
36for cyan foreground
37for white (or gray) foreground
40for black background
41for red background
42for green background
43for yellow (or brown) background
44for blue background
45for purple background
46for cyan background
47for white (or gray) background

Not all commands will work on all systems or display devices.

ls uses the following defaults:

NORMAL 0 Normal (non-filename) text
FILE0 Regular file
DIR 32 Directory
LINK36 Symbolic link
ORPHAN undefined Orphanned symbolic link
MISSING undefined Missing file
FIFO31 Named pipe (FIFO)
SOCK33 Socket
BLK 44;37 Block device
CHR 44;37 Character device
EXEC35 Executable file

A few terminal programs do not recognize the default properly. If all text gets colorized after you do a directory listing, change the NORMAL and FILE codes to the numerical codes for your normal foreground and background colors.

"OTHER TERMINAL TYPES (ADVANCED CONFIGURATION)"

If you have a color-capable (or otherwise highlighting) terminal (or printer!) which uses a different set of codes, you can still generate a suitable setup. To do so, you will have to use the LEFTCODE, RIGHTCODE, and ENDCODE definitions.

When writing out a filename, ls generates the following output sequence: LEFTCODE typecode RIGHTCODE filename ENDCODE, where the typecode is the color sequence that depends on the type or name of file. If the ENDCODE is undefined, the sequence "LEFTCODE NORMAL RIGHTCODE" will be used instead. The purpose of the left- and rightcodes is merely to reduce the amount of typing necessary (and to hide ugly escape codes away from the user). If they are not appropriate for your terminal, you can eliminate them by specifying the respective keyword on a line by itself.

NOTE: If the ENDCODE is defined in the global section of the setup file, it cannot be undefined in a terminal-specific section of the file. This means any NORMAL definition will have no effect. A different ENDCODE can, however, be specified, which would have the same effect.

"ESCAPE SEQUENCES"

To specify control- or blank characters in the color sequences or filename extensions, either C-style \-escaped notation or stty-style ^-notation can be used. The C-style notation includes the following characters:

\a Bell (ASCII 7)
\b Backspace (ASCII 8)
\e Escape (ASCII 27)
\f Form feed (ASCII 12)
\n Newline (ASCII 10)
\r Carriage Return (ASCII 13)
\t Tab (ASCII 9)
\v Vertical Tab (ASCII 11)
\? Delete (ASCII 127)
\nnn Any character (octal notation)
\xnnn Any character (hexadecimal notation)
\_ Space
\\Backslash (\)
\^ Caret (^)
\# Hash mark (#)

Please note that escapes are necessary to enter a space, backslash, caret, or any control character anywhere in the string, as well as a hash mark as the first character.

NOTES

The default LEFTCODE and RIGHTCODE definitions, which are used by ISO 6429 terminals are:

LEFTCODE \e[
RIGHTCODE m

The default ENDCODE is undefined.
