read a
    if [ $a == anand ]
        then
            process_good;;
        else
            process_bad;;
    fi

process_good()
{
    echo "Enter the value"
    read m
    echo "$m"
} 

process_bad()
{
    echo "Bad password" 
}     

Answer 1

要进行调试，请运行脚本并查看哪里失败，然后根据错误进行调整。

您的函数需要在调用之前定义。例如：

function process_good(){
    echo "Enter the value"
    read m
    echo "$m"
    }

function process_bad(){
    echo "Bad password"
    }

echo "Enter the password"
read a

if [ $a == "anand" ]
then
    process_good
else
    process_bad
fi

Answer 2

使用-x调试 shell 脚本的选项。

sh -x test_script.sh
