I have a file with 22 lines. Each line has only 5 different chars, no white space, and each line is 3,278,824 in length. The 5 chars is "-", "A", "B", "C", "D".
Below is an example of the first 25 chars of the first four lines of the file.
my desire output from the above example is
(1) the number of fully matched alphabet characters of each line on all lines: 9. Which are "ABCD" at column 6~9, "D" at column 14, "BBBB" at 16~19, total 9 chars of fully match. Note, "-" does not count.
(2) the fully matched alphabet characters: ABCDDBBBB
(3) each line outputs a file of not matched alphabet characters:
line1: ACBD
line2: ADCC
line3: AAC
line4: AADCD
The program I could utilize includes bash shell, awk, sed, python, perl, R, mysql, java, c etc. I just couldn't find a way to do it.
Please help, thanks in advance~!

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.
