How to make decision structure to change color in a bat?

Question

Hello, I would like to know how to make a decision in the following situation: I have a cmd window with a constant ping, I wanted the script to analyze when the ping is normal the letters of cmd are in the color green, if it was disconnected change to red...

Answer 1

Important to note that to change the color individually per line, you need some helper program.

The rest is basically that:

//salvar como cping.bat ou coisa do tipo
//uso: cping <IP>

@ECHO off
:top
PING -n 1 %1% | find "%1%"
IF NOT ERRORLEVEL 1 GOTO yes
IF ERRORLEVEL 1 GOTO no
:yes
COLOR 2
ECHO Ping OK
GOTO top
:no
COLOR 4
ECHO Ping FAIL
GOTO top

Note that in the case, the color of the whole window changes, to make individual lines of different colors, it is necessary to change the COLOR by some external utility.

Obviously it’s just an outline, but it already has the complete logic for you to adapt as you see fit.

The line IF NOT ERRORLEVEL 1 GOTO yes was more to show the syntax, actually the GOTO no theoretically should suffice.

The syntax of the command is:

COLOR <cor de fundo + cor da letra em hexadecimal>

Colors available in hexadecimal:

0 preto         8 cinza escuro (seria o "preto claro" kkk)
1 azul          9 azul claro
2 verde         a verde claro
3 ciano         b ciano claro
4 vermelho      c vermelho claro
5 magenta       d magenta claro
6 amarelo       e amarelo claro
7 cinza         f branco

In other words, each Nibble (half byte) has 4 bits in this order: [I~] Intensity, [R] Red, [G] Green, [B] Blue:

IRGB -> binário 1011 -> hexadecimal "e" -> Amarelo claro

Effectively generating a value in this format

I R G B  I R G B
^fundo^ ^frente^

Example to change the letters to strong yellow and dark green background:

color 2e

(2e in hexadecimal is 00101110, or G + IRG background )

Coloring the output lines individually

Here’s a utility that does ECHO colorful:

http://www.codeproject.com/Articles/17033/Add-Colors-to-Batch-Files

Follows the code adapted to colored lines separately, using the mentioned utility:

@ECHO off

:top
CECHO {08}
PING -n 1 %1% | find "%1%"

IF NOT ERRORLEVEL 1 GOTO yes
IF ERRORLEVEL 1 GOTO no

:yes
CECHO {0A}Ping OK
GOTO top

:no
CECHO {0C}:Ping FAIL
GOTO top

Answer 2

Something like that?

    @echo off && setlocal enableextensions enabledelayedexpansion

(

if exist "%temp%\bg.b64" del /q /f "%temp%\bg.b64"
if exist "%temp%\bg.exe" del /q /f "%temp%\bg.exe"

) >nul 2>&1 

echo/ & echo/  && call :_base64_to_exe && Certutil.exe -decode "%temp%\bg.b64" "%temp%\bg.exe" >nul 2>&1

if exist "%temp%\bg.exe" ( 

     set _bg="%temp%\bg.exe"

     for %%I in (8.8.8.8 1.1.1.1 2.2.2.2) do (

         for /f "tokens=4 delims=^=" %%i in ('ping -n 1 %%I ^| findstr /i /c:"ms"') do (

             !_bg! print \n && set "_ms=%%~i"&& set /a _ms=!_ms:ms=!

            )

             if  "!_ms!" geq "0" (

                 !_bg! print f " Host" b " online" a " %%I" c ":" e  " !_ms!" a "ms"

                 echo/ & echo/ 

                 set _ms=

                ) else ( 

                 echo/ & echo/ 

                 !_bg! print f " Host" c " offline" b ":" a " %%I"

                 echo/ & echo/ <nul

                ) 

        )

      ) else ( 

       color c && echo/E R R O R: "%temp%\bg.exe" not found...

       2>nul >nul (del /q /f "%temp%\bg64" &  "%temp%\bg.exe" del /q /f "%temp%\bg.exe")

       goto :_end_of_file

      )

:_base64_to_exe
