ProcessBuilder的简单使用

使用ProcessBuilder执行简单的linux命令

---

demo代码:

public static void testProcessBuilder(String command){        boolean err =false;        try {            //初始化ProcessBuilder对象            Process p=new ProcessBuilder(command.split(" ")).start();            //用于存储执行命令的结果            BufferedReader results=new BufferedReader(new InputStreamReader(p.getInputStream()));            String s;            while((s=results.readLine())!=null){                System.out.println(s);            }            //用于存储执行命令的错误信息            BufferedReader errors=new BufferedReader(new InputStreamReader(p.getErrorStream()));            while((s=errors.readLine())!=null){                System.err.println(s);                err=true;            }        } catch (Exception e) {            e.printStackTrace();        }        if(err){            throw new RuntimeException("Error executing "+command);        }    }

command参数的值为要执行的命令,如查看java版本号

public static void main(String[] args) {        String command="java -version";        testProcessBuilder(command);    }
