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测试。但是当我完成编写后,我对其进行了测试,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?
代码如下:
#!/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'
res='\033[0m'
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}"
echo "Verify [Y/N]:"
read verify
if [ "$verify" == "Y" ]; then
random
elif [ "$verify" == "y" ]; then
random
else
echo -e "${yellow}Please install the dependencies.${res}"
fi

那么我的代码到底有什么问题?
要检查你的 shell 脚本,你可以使用壳牌检测。以下是检查代码的输出:
修正后的代码:
#!/bin/bash

ShellCheck - 一个shell脚本静态分析工具
ShellCheck 是一个 GPLv3 工具,可以为 bash/sh shell 脚本提供警告和建议:
终端的屏幕截图,突出显示了有问题的 shell 脚本行。
ShellCheck 的目标是
指出并澄清导致 shell 给出神秘错误消息的典型初学者语法问题。
指出并澄清导致 shell 行为奇怪且违反直觉的典型中级语义问题。
指出细微的警告、极端情况和陷阱,这些可能会导致高级用户的原本可以正常工作的脚本在未来情况下失败。
