linux - 如何重定向到代码中更靠后的函数？

Question

if [[ $adapter == "1" ]]; then

LINE 66 > usepreferredadapter

elif [[ $adapter == "2" ]]; then

echo -e "\e[0mI'm sorry you do not own the requirements to proceed!"
echo "Try using the adapter that's build in , into your computer (not working on Virtualbox or VMware)"
echo -e "\e[31mNote that build in adapters are over all bad for hacking!\e[0m"
echo "Script will exit!"
exit



else

echo "Invalid input!"
echo "Script will exit!"
exit


fi

LINE 89 > function usepreferredadapter(){

在第 66 行中，我希望将用户重定向到第 89 行中的函数，我该怎么做(如果可能的话)？

Answer 1

为了避免这种行为，我建议您将所有代码放在一个主函数中，以便在您需要时加载所有内容

例如

#!/bin/bash
main() {
  if [[ $adapter == "1" ]]; then
    usepreferredadapter
  elif [[ $adapter == "2" ]]; then
    ...
  fi
}

function usepreferredadapter(){
  ...
}

main "$@"

这样，只要在脚本底部调用 main 方法，在哪里定义方法都没有关系
