I have this code in a tool I am currently building: currently building:

while [ $# -gt 0 ]; do
  case "$1" in
    --var1=*)
      var1="${1#*=}"
      ;;
    --var2=*)
      var1="${1#*=}"
      ;;
    --var3=*)
      var1="${1#*=}"
      ;;
    *)
      printf "***************************\n
              * Error: Invalid argument.*\n
              ***************************\n"
  esac
  shift
done

I have many options to add, but five of my options should be saved as arrays. So if I call the tool, let's say from the shell using something like this:
./tool --var1="2" --var1="3" --var1="4" --var1="5" --var2="6" --var3="7"

How can I save the value of var1 as an array? Is that possible? And, if so, what is the best way to deal with these arrays in terms of efficiency if I have too many of them?.

I have this code on my tool, that I currently building:

while [ $# -gt 0 ]; do
  case "$1" in
    --var1=*)
      var1="${1#*=}"
      ;;
    --var2=*)
      var1="${1#*=}"
      ;;
    --var3=*)
      var1="${1#*=}"
      ;;
    *)
      printf "***************************\n
              * Error: Invalid argument.*\n
              ***************************\n"
  esac
  shift
done

So I have many options to add, but five of my options should be put inside array. So if I call the tool, let's say from the shell something like this:
./tool --var1="2" --var1="3" --var1="4" --var1="5" --var2="6" --var3="7" As you can see here, var1 is an array, should be! So my first question is that possible?? And if so what is the best way to deal with these array in term of the efficiency, if I have too many of them??.

So guys I would really appreciate your help, since I am new with bash script.

Thanks!!
