关于Bash脚本中的Switch Case

Question

I'm newbie in bash script, I want to create a switch case without "break" like java code below

switch(choice) {
    case 1: 
           System.out.println("1");
    case 2:
           System.out.println("2");
}

choice = 1

output: 1
        2

so ... how can I do that in bash script :(

Answer 1

Prior to bash 4, you couldn't; at most one block of commands in a case statement would be executed. bash 4 introduced the ;& case terminator, which causes fall-through.

case $choice in
    1) echo 1 ;&
    2) echo 2 ;;
