This utility which Linux-only creature output commands to set the LS_COLORS environment variable.
dircolors [OPTION]... [FILE]
If FILE is specified, read it to determine which colors to use for which file types and extensions. Otherwise, a precompiled database is used. For details on the format of these files, run `dircolors --print-database'.
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
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:
ISO 6429 color sequences are composed of sequences of numbers separated by semicolons. The most common codes are:
0 to restore default color 1 for brighter colors 4 for underlined text 5 for flashing text 30 for black foreground 31 for red foreground 32 for green foreground 33 for yellow (or brown) foreground 34 for blue foreground 35 for purple foreground 36 for cyan foreground 37 for white (or gray) foreground 40 for black background 41 for red background 42 for green background 43 for yellow (or brown) background 44 for blue background 45 for purple background 46 for cyan background 47 for 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 FILE 0 Regular file DIR 32 Directory LINK 36 Symbolic link ORPHAN undefined Orphanned symbolic link MISSING undefined Missing file FIFO 31 Named pipe (FIFO) SOCK 33 Socket BLK 44;37 Block device CHR 44;37 Character device EXEC 35 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.
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.
\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.
