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.
EXAMPLES
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
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
|
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
|
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.
