Linux shell脚本读取用户输入的参数

新建一个test.sh文件

#!/bin/sh
echo "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"
fi
done

运行测试日志如下：

[root@master batch]# sh test.sh
