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




       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 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.


       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 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

       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.




              enables debug output.


       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.


       terminal-colors.d  is  part  of  the util-linux package and is available from Linux Kernel
