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: + +____ +[cols=",",] +|=== +|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: + +____ +[cols=",",] +|=== +|*\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.
