Welcome crepe6,
Please always include the output from uname -a wrapped in CODE tags so we know which OS and version you are using.
Please confirm the context of this issue, i.e. is it homework/course assignment so we know how to answer.
If you are looking for 3 or more of the same character in succession (given that double-letters are valid in many words) would you be okay with some Perl?
An expression something like /(.)\1\1/ might help I think, i.e. match any character followed by the same twice. You might want to refine that to letters only to avoid matching on white-space or numbers if they are in your file too.
Of course, this doesn't match kraark, tattarrattat, wibblewobblesnoozydunno or even Hh_ee_ll_ll_oo_WW_oo_rr_ll_dd if they are in (or added to) the list, so should they be in or out?
Is there a dictionary list you can match against if you want real words only?
You need to be clearer to your criteria, after answering if this is homework or if not giving the context so we can most suitably be able to progress this.
Kind regards,
Robin

set_color
set_color(1) fish set_color(1)
NAME
set_color - set_color - set the terminal color
set_color - set the terminal color
Synopsis
set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR]
Description
Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple,
cyan, white and normal.
o -b, --background Set the background color
o -c, --print-colors Prints a list of all valid color names
o -h, --help Display help message and exit
o -o, --bold Set bold or extra bright mode
o -u, --underline Set underlined mode
o -v, --version Display version and exit
Calling set_color normal will set the terminal color to whatever is the default color of the terminal.
Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey
font color, while set_color --bold white will result in a white font color.
Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator.
set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and
incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of
ncurses and recompile fish against it in order to fix this issue.
