How to change line color in CMD?

Question

cmd/bat

I myself don’t understand a damn thing in cmd, so I looked for a solution on the Internet.
As far as I understand, color is not used for this. it changes color throughout the session. But they use some kind of hack with the findstr command , which can explicitly specify the color of the message it displays.
Here's what dug up:

:write
  setlocal
  :write1
  set "tempFolder=%TEMP%\%~n0.%time:~-2%.%random%"
  md "%tempFolder%" 2>nul || goto write1
  pushd %tempFolder%
  set /p .=.<nul>"%~2"
  findstr /a:%~1 /c:"." /s "%~2"
  popd
  rd /s /q "%tempFolder%" 2>nul
endlocal & exit /b

:writeLn
  call :write %1 "%~2"
  echo:
exit /b

This stuff works almost exactly as it should, except it adds a colon and a period at the end. That is, the call call :write 0A "My Charona"will return My Charona:., where My Charona and the colon will be green, and the period will be the default.
Some lines of code are almost clear to me ( findstr /a:%~1 /c:"." /s "%~2"), some are black magic ( set /p .=.<nul>"%~2").
Is there any way to get rid of the last two characters in the string output by findstr ?
By the way, yes: if you remove all operations with directories from the code, the functionality does not change at all, everything works the same.

Is that not an option?

Answer 3

set /p .=.<nul>"%~2"- writes a dot to the file "%~2" without a newline.
The standard option echo .>"%~2"is to add line feed/carriage return characters at the end of the file.
findstr /a:%~1 /c:"." /s "%~2"- searches for a point in the file "%~2" and displays it in the color specified in "%~1". Due to the presence of the /s key, the name of the file in which the point was found is displayed, and the previous command creates a file with a name equal to the search phrase, i.e. the effect of the output of the phrase is created.
You can get rid of the dot by replacing it with a space, but I don’t think you can get rid of the colon.
In general, this does not look like a normal way of output. If you really want colored letters in a batch file, then look towards nircmd or similar multifunctional command line utilities, perhaps there is such a feature there.
