Question

以下是剧本。

string FindGrade(double score,string rule)
{

 List<Scoremaster> scores=(from p in dbcontext.Scoremasters
                             where p.GradeRule==rule
                             select p).ToList();

//how can i check the score input of the function belongs to which category from this list using Linq

//example   FindGrade(3,5) = B2  FindGrade(4,5) = A2
//example   FindGrade(7,10) = A2  FindGrade(4,10) = C
//example   FindGrade(17,20) = A1  FindGrade(10,20) = B1                             
}

它只是关闭而启动无效。

我正在运行以下代码

#!/bin/bash
if [ ! -s $CATALINA_HOME ]; then
echo "Error: CATALINA_HOME not set!!!"
exit -1
fi

SHUTDOWN_SCRIPT="$CATALINA_HOME/bin/shutdown.sh"
STARTUP_SCRIPT="$CATALINA_HOME/bin/startup.sh"

#execute shutdown.sh
echo "Doing Shutdown"
$SHUTDOWN_SCRIPT
sleep 5
#execute startup.sh
echo "Doing Startup"
$STARTUP_SCRIPT

exit 0

我在.bat文件中遇到了类似的问题，我用

修复了它

Runtime rn = Runtime.getRuntime();
Process proc; 
proc = rn.exec("/script/restart.sh");
proc.waitFor();

使用“cmd / c start”调用解决了我的问题。对.sh文件的任何类似建议？

Answer 1

检查文件权限是否具有执行权限，如果没有设置执行权限。

执行which bash它会在bash或/bin/bash yourShell.sh中使用示例/bin/sh yourShell.sh或Runtime#exec返回ProcessBuilder尝试的路径（推荐）

saravana@ubuntu:~$which bash /bin/bash

    String[] commmands = { "/bin/bash", "/script/restart.sh" }; // or { "/bin/sh", "/script/restart.sh" }
    Runtime.getRuntime().exec(commmands); //or
    new ProcessBuilder(commmands).start(); //Recommended

shell脚本与java Runtime不一致
