NAME         top

       terminal-colors.d - configure output colorization for various
       utilities

SYNOPSIS         top

       /etc/terminal-colors.d/[[name][@term].][type]

DESCRIPTION         top

       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 "[email protected]". 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         top

       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:
          ┌────┬───────────────────────┐

   Escape sequences
       To specify control or blank characters in the color
       sequences, C-style \-escaped notation can be used:

          │ \# │ 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.

COMPATIBILITY         top

       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.
