意外标记“}”附近的语法错误

Question

我正在编写一个程序，其中包含我兄弟要求的一些随机基准。但是当我写完它时，我去测试它，结果如下：

./benchmarksuite.sh: line 45: syntax error near unexpected token `}'
./benchmarksuite.sh: line 45: `}'

那么我的代码到底有什么问题呢？

这是代码：

#!/bin/bash

drivetest()
{
        echo "How much data do you want to write (in MiB):"
        read data
        echo "Are you sure you want to perform a $data MiB write onto your disk?[Y/N]"
        read confirm
        if [ "$confirm" == "Y" ]; then
                dd bs=1M count=$data if=/dev/zero of=test conv=fdatasync
        elif [ "$verify" == "y" ]; then
                dd bs=1M count=$data if=/dev/zero of=test conv=fdatasync
        else
                echo "Exiting the test."
        fi


stresstest()
{
        echo "How long is your stress(tips: Use letters along numbers like s,m,h. If you type number with OUT letter, default as second):"
        read time
        echo "How many CPU workers do you want?"
        read cpu_worker
        sudo stress --cpu $cpu_worker --timeout $time
        echo ""
        echo -e "${yellow}Thermal results:${res}"
        sensors
}

random()
{
        echo "           MENU             "
        echo "Type 1 for a drive test.    "
        echo "Type 2 for a stress test.   "
        echo "Type 3 to perform all tests."
        echo "Type other stuffs to exit.  "
        read value
        if [ "$value" == "1" ]; then
                drivetest
        if [ "$value" == "2" ]; then
                stresstest
        if [ "$value" == "3" ]; then
                {
                        drivetest
                        stresstest
                }
}



yellow='\033[1;33m'

echo -e "${yellow}This script is depended on stress-ng and lm-sensors. Please be sure that you have those package installed.${res}"
echo "Verify [Y/N]:"

if [ "$verify" == "Y" ]; then

        random

那么我的代码到底有什么问题呢？

要检查您的 shell 脚本，您可以使用ShellCheck。这是检查代码的输出：

1. 你少了几个fi。

   添加fis 会产生一个新错误：

   

2. drivetest() 似乎缺少结束语 }

   更正此问题会给您带来一些警告（我将留给您修复）：

   

更正的代码：

#!/bin/bash

drivetest()
{
        echo "How much data do you want to write (in MiB):"
        read data
        echo "Are you sure you want to perform a $data MiB write onto your disk?[Y/N]"
        read confirm
        if [ "$confirm" == "Y" ]; then
                dd bs=1M count=$data if=/dev/zero of=test conv=fdatasync
        elif [ "$verify" == "y" ]; then
                dd bs=1M count=$data if=/dev/zero of=test conv=fdatasync
        else
                echo "Exiting the test."
        fi
}


stresstest()
{
        echo "How long is your stress(tips: Use letters along numbers like s,m,h. If you type number with OUT letter, default as second):"
        read time
        echo "How many CPU workers do you want?"
        read cpu_worker
        sudo stress --cpu $cpu_worker --timeout $time
        echo ""
        echo -e "${yellow}Thermal results:${res}"
        sensors
}

random()
{
        echo "           MENU             "
        echo "Type 1 for a drive test.    "
        echo "Type 2 for a stress test.   "
        echo "Type 3 to perform all tests."
        echo "Type other stuffs to exit.  "
        read value
        if [ "$value" == "1" ]; then
                drivetest
        fi
        if [ "$value" == "2" ]; then
                stresstest
        fi
        if [ "$value" == "3" ]; then
                {
                        drivetest
                        stresstest
                }
        fi
}

echo -e "${yellow}Warning:${res}"
echo -e "${yellow}This script is depended on stress-ng and lm-sensors. Please be sure that you have those package installed.${res}"
