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.

FILES

       $HOME/.config/terminal-colors.d
       /etc/terminal-colors.d

ENVIRONMENT

              enables debug output.

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.
