SYNOPSIS         top


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:

              Turns off output colorization for all compatible utilities.

       enable Turns on output colorization; any matching disable files are

       scheme Specifies colors used for output.  The file format may be
              specific to the utility, the default format is described

       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.


       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

   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

       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.

EXAMPLE         top

       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


       The terminal-colors.d functionality is currently supported by all
       util-linux utilities which provides colorized output.  For more
