linux shell 脚本读取用户输入的参数如何解决？

while read var

do

echo $var

done

这样也是可以的，没错。

想回退的话用 ctrl+backspace

新建一个test.sh文件

#!/bin/shecho "1 : For Test"echo "2 : For nohup &" while true do echo -n "please enter the number:" read line echo "$line" if [[ $line = "1" ]]then echo "For Test" elif [[ $line = "2" ]]then echo "For nohup &" else echo "can not find command" fidone

运行测试日志如下：

[root@master batch]# sh test.sh1 : For Test2 : For nohup &please enter the number:11For Testplease enter the number:22For nohup &please enter the number:33can not find commandplease enter the number:sssscan not find commandplease enter the number:
