今天在linux环境下需要做一个简单的测试，使用java调用bash命令。

源码

public class HelloWorld { 
    private String helloMsg = "Hello World!";
    private static String cmd = "/root/test/1.sh";

    public static void main(String[] args) { 
        HelloWorld hw = new HelloWorld();
        execCommand(cmd);
    }

    public HelloWorld() {
        System.out.println(helloMsg);
    }


    public  static boolean execCommand(String cmd) {

        Process process = null;        
        try {
             process = Runtime.getRuntime().exec(cmd);
            process.waitFor();             
        } catch (Exception e) {        
            return false;
        } finally {
            try {
                process.destroy();             
            } catch (Exception e) {  

            }
        }
        return true;
    } 
    
}

编译

javac  HelloWorld.java 

运行

java  HelloWorld
