Bug sh to grep and replace text files
Hello I was wondering what is a way you can put in your code that acts like goto for bash in windows ?

lets say i have a if yes or no question how would i go about doing that?

Also how can i search for text inside a file and insert my text into that part if you dont mind me asking?

If you need a GOTO, you did something wrong, or chose the wrong language. Windows batch programs require the use of GOTO because it lacks constructs like blocks, loops, functions, and case/switch decisions. The simplest case for your example would be:
Code:
read yesno
case ${yesno} in
    [Yy] ) echo "Yes" ;;
    [Nn] ) echo "No" ;;
    * ) echo "Other" ;;
esac

For loops (for/while/until) there's break and continue.

When i use something like

Code:
read yesno
case ${yesno} in
    [Yy] ) echo "Yes" ;;
    [Nn] ) echo "No" ;;
    * ) echo "Other" ;;
esac

case ${yesno} in
  [Yy])
    do echo "hi"
  ;;
  [Nn])
    do echo " test"
  ;;
esac

it just acts as if its executing and does nothing ?
