Java调用linux系统shell执行命令

在Linux操作系统上可以执行本地命令，并返回字符串。

在CentOS 6.3上已经测试正常运行。

 

package com.cz.shell;  

import java.io.BufferedReader;  

import java.io.IOException;  

import java.io.InputStreamReader;  

import java.io.OutputStreamWriter;  

import java.io.PrintWriter;  

import java.util.logging.Level;  

import java.util.logging.Logger;  

public class Shell {  

public static String ec(String command) throws InterruptedException {  

String returnString = "";  

Process pro = null;  

Runtime runTime = Runtime.getRuntime();  

if (runTime == null) {  

System.err.println("Create runtime false!");  

}  

try {  

pro = runTime.exec(command);  

BufferedReader input = new BufferedReader(new InputStreamReader(pro.getInputStream()));  

PrintWriter output = new PrintWriter(new OutputStreamWriter(pro.getOutputStream()));  

String line;  

while ((line = input.readLine()) != null) {  

// System.out.println(line);  

returnString = returnString + line + "\n";  

}  

input.close();  

output.close();  

pro.destroy();  

} catch (IOException ex) {  

Logger.getLogger(Shell.class.getName()).log(Level.SEVERE, null, ex);  

}  

return returnString;  

}  

}
