[Batch] Check for character presence in variable

Solved
Ekiam -  
Bonjour,

I am facing a problem because I would like to add an option such that when a certain string is entered, it goes to a label. It's quite complicated to explain, but here is the principle.
In fact, if the person puts in the variable choice: 1 /random, then after executing what is in label 1, it should go to the Random label and perform the actions. However, I can't seem to do that.
So we would have: %choix%=1 /random 

@echo off

chcp 28591 > nul

:menu
cls

set /p choix="Something to say? "

if %choix%==0 goto :0
if %choix%==1 goto :1
if %choix%==end goto :end
if %choix:~1%==/random goto :Random

goto :menu

:0
echo You said 0
pause > nul
goto :end

:1
echo You said 1
pause > nul
goto :end

:Random
cls
echo %RANDOM%
pause

:end
echo It's the end
pause
exit

    Good evening,

    It's very simple, there is not just IF that allows you to create a condition, but also && and ||: 

    @echo off

    chcp 28591 > nul

    :menu
    cls

    set /p choice="Something to say? "

    echo %choice% | find "0" && goto :0
    echo %choice% | find "1" && goto :1
    if %choice%==end goto :end

    goto :menu

    :0
    echo You said 0
    echo %choice% | find "random" && goto :Random
    pause > nul
    goto :end

    :1
    echo You said 1
    echo %choice% | find "random" && goto :Random
    pause > nul
    goto :end

    :Random
    cls
    echo %RANDOM%
    pause

    :end
    echo It's the end
    pause
    exit

      Good evening,

      Thank you, it's exactly what I was looking for but it's strange, I couldn't find it anywhere.

      I would just like to know if it is possible for it not to return what is in the variable.
      (I would simply like it to check that the variable contains random but without writing in the console what the variable %choix% contains)

      I hope I have been clear enough.

      @EkiamIt is possible to redirect the output to null, like this: 

      @echo off

      chcp 28591 > nul

      :menu
      cls

      set /p choix="Anything to say? "

      echo %choix% | find "0" >nul && goto :0
      echo %choix% | find "1" >nul && goto :1
      if %choix%==end goto :end

      goto :menu

      :0
      echo You said 0
      echo %choix% | find "random" >nul && goto :Random
      pause > nul
      goto :end

      :1
      echo You said 1
      echo %choix% | find "random" >nul && goto :Random
      pause > nul
      goto :end

      :Random
      cls
      echo %RANDOM%
      pause

      :end
      echo It's the end
      pause
      exit
