我需要一些关于我的菜单驱动的 shell 脚本的建议。我希望此脚本的最终用户能够在提示输入选项时提供多个选项。用户也可以输入一个选项,或者他/她可以输入多个选项。
例如。该脚本应该能够处理这两个选项:
Please enter any option or options between [1 - 4]: 1 2 3
Please enter any option or options between [1 - 4]: 1
请让我知道如何更改我的脚本以反映这一点。
以下是我的脚本代码供您参考:
#!/bin/sh
while :
do
clear
echo " ******** Task performing script ******** "
echo "1. task1 "
echo
echo "2. task2 "
echo
echo "3. task3"
echo
echo "4. Exit"
echo
echo -n "Please enter any option or options between [1 - 4]"
read opt;
case $opt in
1)
echo "Performing task1 . . . .";
for i in `cat test`
do
...............
...............
done;;
2)
echo "Performing task2 . . . .";
for i in `cat test`
do
...............
...............
done;;
3)
echo "Performing task3 . . . .";
for i in `cat test`
do
...............
...............
done;;
4)
echo "Bye $USER";
exit 1;;
*)
echo "$opt is an invaild option";
echo "Press [enter] key to continue. . .";
read enterKey;;
esac
done
