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 terminal 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.
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/terminal-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 sequences.
Color names
black, blink, blue, bold, brown, cyan, darkgray, gray, green, halfbright, lightblue,
lightcyan, lightgray, lightgreen, lightmagenta, lightred, magenta, red, reset, reverse,
and yellow.
ANSI color sequences
The 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 │
├───┼────────────────────────────────┤

└───┴────────────────────────────────┘
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-colors.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 interpreted as introducing a comment.
ENVIRONMENT
TERMINAL_COLORS_DEBUG=all
enables debug output.
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 terminal:
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 output. For more details always see the
COLORS section in the man page for the utility.
