TERMINAL-COLORS.D(5) File formats TERMINAL-COLORS.D(5) NAME terminal-colors.d - configure output colorization for various utilities SYNOPSIS /etc/terminal-colors.d/[[name][@term].][type] DESCRIPTION Files in this directory determine the default behavior for utilities when coloring output. The name is a utility name. The name is optional and when none is specified then the file is used for all unspecified utilities. The term is a terminal identifier (the TERM environment variable). The ter- minal identifier is optional and when none is specified then the file is used for all unspecified terminals. The type is a file type. Supported file types are: disable Turns off output colorization for all compatible utilities. See also the NO_COLOR environment variable below. enable Turns on output colorization; any matching disable files are ignored. scheme Specifies colors used for output. The file format may be specific to the utility, the default format is described below. If there are more files that match for a utility, then the file with the more specific filename wins. For example, the filename "@xterm.scheme" has less priority than "dmesg@xterm.scheme". The lowest priority are those files without a utility name and terminal identifier (e.g., "disable"). The user-specific $XDG_CONFIG_HOME/terminal-colors.d or $HOME/.config/ter- minal-colors.d overrides the global setting. DEFAULT SCHEME FILES FORMAT The following statement is recognized: name color-sequence The name is a logical name of color sequence (for example "error"). The names are specific to the utilities. For more details always see the COLORS section in the man page for the utility. The color-sequence is a color name, ASCII color sequences or escape se- quences. Color names black, blink, blue, bold, brown, cyan, darkgray, gray, green, halfbright, lightblue, lightcyan, lightgray, lightgreen, lightmagenta, lightred, ma- genta, red, reset, reverse, and yellow. ANSI color sequences The color sequences are composed of sequences of numbers separated by semi- colons. 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) fore- | | | ground | +----+---------------------------+ | | | | 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) back- | | | ground | +----+---------------------------+ Escape sequences To specify control or blank characters in the color sequences, C-style \-escaped notation can be used: +----+------------------------+ | | | | \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) | +----+------------------------+ | | | | \_ | 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. For example, to use a red background for alert messages in the output of dmesg(1), use: echo 'alert 37;41' >> /etc/terminal-col- ors.d/dmesg.scheme Comments Lines where the first non-blank character is a # (hash) are ignored. Any other use of the hash character is not inter- preted as introducing a comment. ENVIRONMENT TERMINAL_COLORS_DEBUG=all enables debug output. NO_COLOR if defined, this disables output colorization unless explicitly enabled by a command-line option. See https://no-color.org/ for more details. Supported since util-linux version 2.41. FILES $XDG_CONFIG_HOME/terminal-colors.d $HOME/.config/terminal-colors.d /etc/terminal-colors.d EXAMPLE Disable colors for all compatible utilities: touch /etc/terminal-colors.d/disable Disable colors for all compatible utils on a vt100 termi- nal: touch /etc/terminal-colors.d/@vt100.disable Disable colors for all compatible utils except dmesg(1): touch /etc/terminal-colors.d/disable touch /etc/terminal-colors.d/dmesg.enable COMPATIBILITY The terminal-colors.d functionality is currently supported by all util-linux utilities which provides colorized out- put.
